Searching for variability in the globular cluster Messier 4
Creators: name: Ferdman, Robert Daniel
Publisher: name: University of British Columbia
Year: 2009

description: Time-series data taken with the Hubble Space Telescope (HST) of a field six core radii (~ 5') from the centre of the globular cluster Messier 4 (M4) have been analysed in search of variable objects. These observations consisted of 98 x 1300 s exposures in the F606W (V) filter, and 148 x 1300 s exposures in the F814W (I) filter, covering a period of about 10 weeks in early 2001. Various selection criteria were employed to select candidate variable stars. These included: selection of outliers in the RMS and variability index vs. magnitude distributions, as well as selection of stars in the colourmagnitude diagram of the cluster that lie above the main sequence (MS) and between the MS and white dwarf sequence. White dwarf stars that lie within the empirical ZZ Ceti instability region were also selected as candidates. Period searches were then performed on the selected candidates using the phase dispersion minimization (PDM) technique. The reliability of the P DM search results for this dataset was tested using synthetic light curves of eclipsing binary star and sinusoidal light curves at a few different periods. Results from this analysis showed that there are probably no eclipsing binary stars or periodic variables with periods on the order of a half a day, down to limiting magnitudes of V ~ 25 and I ~ 24. This is consistent with the absence of contact binaries such as the W Ursae Majoris systems. However, one candidate variable star does show a increase in brightness of ~ 0.1 magnitudes in both bandpasses; this rise in amplitude seems to last for a few days. If this object is periodic, its period is too long to detect given the time sampling of the data. Possible explanations concerning the nature of this object include a binary system with a white dwarf primary and a low-mass main sequence secondary, or a B Y Draconis variable star. Both of these objects can exhibit nonperiodic flaring or low amplitude, periodic variability in the light curve due to starspots.

description: The objective of this paper was to provide the U.S. dairy industry with empirical estimates of Hong Kong's derived demand for imported cheese differentiated by source country of production. These estimates were used to simulate the effects of European Union (EU) subsidy reductions on the U.S. share of Hong Kong cheese imports. Simulation results suggested that Oceania was the primary beneficiary from EU subsidy reductions. Hong Kong cheese imports from the U.S. were expected to increase by 12% if subsidy reductions continue at the same pace as the 1994 GATT agreement and 21% if reductions were twice the pace.

description: An exact fully-localized extremal supergravity solution for N_2 D2 branes and N_6 D6 branes, which is dual to 3-dimensional supersymmetric SU(N_2) gauge theory with N_6 fundamentals, was found by Cherkis and Hashimoto. In order to consider the thermal properties of the gauge theory we present the non-extremal extension of this solution to first order in an expansion near the core of the D6 branes. We compute the Hawking temperature and the black brane horizon area/entropy. The leading order entropy, which is proportional to N_2^{3/2} N_6^{1/2} T_H^2, is not corrected to first order in the expansion. This result is consistent with the analogous weak-coupling result at the correspondence point N_2 ~ N_6.

description: Kibble-Zurek mechanism (KZM) is a universal framework which could in principle describe phase transition phenomenon in any system with required symmetry properties. However, a conflicting observation termed anti-KZ behavior has been reported in the study of ferroelectric phase transition, in which slower driving results in more topological defects [S. M. Griffin, et al. Phys. Rev. X. 2, 041022 (2012)]. Although this research is significant, its experimental simulations have been scarce until now. In this work, we experimentally demonstrate anti-KZ behavior under noisy control field in three kinds of quantum phase transition protocols using a single trapped Yb ion. The density of defects is studied as a function of the quench time and the noise intensity. We experimentally verify that the optimal quench time to minimize excitation scales as a universal power law of the noise intensity. Our research sets a stage for quantum simulation of such anti-KZ behavior in two-level systems and reveals the limitations of the adiabatic protocols such as quantum annealing.

description: The analogues of Arimoto's definition of conditional Rényi entropy and Rényi mutual information are explored for abstract alphabets. These quantities, although dependent on the reference measure, have some useful properties similar to those known in the discrete setting. In addition to laying out some such basic properties and the relations to Rényi divergences, the relationships between the families of mutual informations defined by Sibson, Augustin-Csiszár, and Lapidoth-Pfister, as well as the corresponding capacities, are explored.

description: We present an overview of the sample of northern hemisphere white dwarfs within 40 pc of the Sun detected from $Gaia$ Data Release 2 (DR2). We find that 521 sources are spectroscopically confirmed degenerate stars, 111 of which were first identified as white dwarf candidates from $Gaia$ DR2 and followed-up recently with the William Herschel Telescope and Gran Telescopio Canarias. Three additional white dwarf candidates remain spectroscopically unobserved and six unresolved binaries are known to include a white dwarf but were not in our initial selection of white dwarfs in the $Gaia$ DR2 Hertzsprung-Russell diagram (HRD). Atmospheric parameters are calculated from $Gaia$ and Pan-STARRS photometry for all objects in the sample, confirming most of the trends previously observed in the much smaller 20 pc sample. Local white dwarfs are overwhelmingly consistent with Galactic disc kinematics, with only four halo candidates. We find that DAZ white dwarfs are significantly less massive than the overall DA population ($\overline{M}_\mathrm{DAZ} = 0.59\,\mathrm{M}_\odot$, $\overline{M}_\mathrm{DA} = 0.66\,\mathrm{M}_\odot$). It may suggest that planet formation is less efficient at higher mass stars, producing more massive white dwarfs. We detect a sequence of crystallised white dwarfs in the mass range from $0.6\ \lesssim M/\mathrm{M}_\odot \lesssim\ 1.0\,$ and find that the vast majority of objects on the sequence have standard kinematic properties that correspond to the average of the sample, suggesting that their nature can be explained by crystallisation alone. We also detect 56 wide binaries including a white dwarf and 26 double degenerates.

description: The oil produced from high oleic acid soybeans (HOS) offers benefits to both consumers and food manufacturers. It is lower in saturated fat and more heat-stable than commodity-grade soybean oil. Optimum Quality Grains L.L.C. is working with seed distributors, elevators, and crushers across the Midwestern U.S. to develop a new supply chain which keeps the HOS and the resulting oil separate (identity preserved (IP)) from commodity-grade soybean oil. This case illustrates the challenges and key issues facing three players - an agricultural inputs dealer, a grain elevator, and a soybean crusher - that must decide whether to join the new supply chain as the HOS research commercialization. The case can be used to create a discussion about how each player can create and capture value from this specialty crop. The case works well either as part of an undergraduate capstone course or a graduate course in agribusiness, or in an executive education course, especially such a course aimed at managers from seed and life sciences companies.

description: We study the fundamental problem of two gas species in two dimensional velocity space whose molecules collide as hard circles in the presence of a flat boundary and with dependence on only one space dimension. The case of three-dimensional velocity space is a generalization. More speciffically the linear problem arising when the second gas dominates as a flow with constant velocity (and hence zero temperature) is considered. The boundary condition adopted consists of prescribing the outgoing velocity distribution at the wall. It is discovered that the presence of the boundary under general assumptions on the outgoing distribution ensures the convergence of a series of path integrals and thus a convenient representation for the solution is obtained.

description: The internet and digital device usage has become an integral part of everyone’s life and among them majority are young adults. Ease of access to digital devices, availability of the internet facilities and prominence given to Information Communication Technology in education system are the contributing factors towards this trend in Sri Lanka. Thus, this article explores the general profile of the young adults reflecting their practices towards the internet and digital device usage. In accordance with this aim, digital behaviour of young adults related to the internet consumption and digital media platforms usage such as frequency, time spent, type of content followed, viewed and subscribed etc. are illustrated. Subsequently, research findings reveal that the majority of the young adults who pursue either secondary or tertiary education, log on to digital media platforms in a daily basis by their smart phones (91%) through consuming personal mobile data (90%) and they log in to online platforms while travelling. Furthermore, the frequently accessed digital media platforms are Facebook (98%) and YouTube (93%) and mostly accessed in between 6-8 am and 6-10 pm. At the same time, this study discloses that youth’s perception and conduct towards pre roll and pop-up advertisements are not satisfactory since they often skip pre roll advertisements and do not access information provided by the pop-up advertisements.

description: Spin polarized scanning tunneling microscopy is used to directly image topological magnetic textures in thin films of MnGe, and to correlate the magnetism with structure probed at the atomic-scale. Our images indicate helical stripe domains, each characterized by a single wavevector Q, and their associated helimagnetic domain walls, in contrast to the 3Q magnetic state seen in the bulk. Combining our surface measurements with micromagnetic modeling, we deduce the three-dimensional orientation of the helical wavevectors and gain detailed understanding of the structure of individual domain walls and their intersections. We find that three helical domains meet in two distinct ways to produce either a "target-like" or a "pi-like" topological spin texture, and correlate these with local strain on the surface. We further show that the target-like texture can be reversibly manipulated through either current/voltage pulsing or applied magnetic field, a promising step toward future applications.

description: We have studied the nature and dynamics of spin-dependent charge carrier recombination in Tris(8-hydroxyquinolinato) aluminum (Alq$_3$) films in light emitting diodes at room temperature using continuous wave and pulsed electrically detected magnetic resonance (EDMR) spectroscopy. We found that the EDMR signal is dominated by an electron-hole recombination process, and another, weaker EDMR signal whose fundamental nature was investigated. From the pulsed EDMR measurements we obtained a carrier spin relaxation time, $T_2 = 45\pm 25$ ns which is much shorter than $T_2$ in conjugated polymers, but relatively long for a molecule containing elements with high atomic number. Using multi-frequency continuous wave EDMR spectroscopy, we obtained the local hyperfine field distributions for electrons and holes, as well as their respective spin-orbit coupling induced g-factor and g-strain values.

description: Barriers to the adoption of grid pricing by fed cattle producers are investigated over a 206-week period (January 1997 to December 2000). The empirical findings document the following potential barriers to adoption: (1) when fed cattle are evaluated on a grid pricing system versus a dressed weight pricing system, a price differential per cwt. and a per-head revenue differential exists over time, (2) the price differential per cwt. is subject to seasonal variation, resulting in variability in the monetary incentive to market-fed cattle on a grid relative to selling cattle at an average price, and (3) the variability in per-head grid revenue is consistently higher than per-head dressed weight revenue variability over time. The marketing implications for fed cattle producers are (1) the incentive to market on a grid versus selling fed cattle dressed weight is lower in the spring relative to the fall; (2) marketing on a grid does reward producers selling high quality steers and the incentive to market higher quality cattle on a grid has been increasing over the 206-week period of the study; (3) grid discounts levied on lower quality cattle have also been increasing over time; (4) selling on a grid results in higher per-head revenue variability relative to selling fed cattle dressed-weight, indicating that while producers are rewarded when selling high quality cattle on a grid relative to selling at an average price, it is also a riskier marketing option relative to average pricing; and (5) the 4-year trend in the price differential per cwt. for above-average cattle has been positive but negative for the below-average quality cattle. This trend indicates that packers are providing monetary incentives and disincentives based on overall cattle quality when fed cattle are sold on a grid relative to purchasing fed cattle at an average price. Corresponding with this shift in the incentive structure of grid pricing, overall carcass quality has improved in the region from which data was collected. However, the empirical evidence supports the conclusion that the barriers to the adoption of grid pricing continue to exist.

description: Makroskopskom analizom kremiranih ljudskih ostataka moguće je dobiti osnovne antropološke informacije, kao i podatke o procesu kremiranja i o obredu koji ga je pratio. Međutim, najčešće su podaci veoma oskudni usled delovanja vatre koja transformiše kosti i dovodi do velike fragmentovanosti i loše očuvanosti skeleta. Budući da je broj informacija dobijenih makroskopskom analizom ograničen, neophodan je interdisciplinarni pristup koji omogućava bolju interpretaciju i razumevanje kremiranih ljudskih ostataka. Ovakav pristup analizi ljudskih i životinjskih ostataka iz pet urni i jedne sahrane van urne, sa lokaliteta Konopište, omogućio nam je da rekonstruišemo temperaturu koja je postignuta na lomači, broj individua koje su sahranjene u jednoj urni, kao i to koje životinje su predstavljale deo obreda. Pored toga, primenom SEM-EDX analiza detektovana je vrsta metala prisutnog u tragovima na kostima, kao i hemijski sastav fragmentovanih artefakata koji su usled vatre doživeli visok stepen destrukcije i gde je makroskopski bilo nemoguće utvrditi kojoj vrsti materijala su pripadali. Osteološki materijal sa lokaliteta Konopište pripada periodu kasnog bronzanog doba i periodu prelaska iz bronzanog u gvozdeno doba.

description: We consider the entanglement of orthogonal generalized Bernoulli states in two separate single-mode high-$Q$ cavities. The expectation values and the correlations of the electric field in the cavities are obtained. We then define, in each cavity, a dichotomic operator expressible in terms of the field states which can be, in principle, experimentally measured by a probe atom that ``reads'' the field. Using the quantum correlations of couples of these operators, we construct a Bell's inequality which is shown to be violated for a wide range of the degree of entanglement and which can be tested in a simple way. Thus the cavity fields directly show quantum non-local properties. A scheme is also sketched to generate entangled orthogonal generalized Bernoulli states in the two separate cavities.

description: The competition in the fashion retail industry of Sri Lanka is reaching new heights due to various demands of the fashion consumers in Sri Lanka. As per the significant growth in the fashion retailing sector in Sri Lanka the marketers need to define the strategies to address their customer intentions. Especially with the rapid growth of the social networking sites especially Facebook in Sri Lanka, fashion retailers have to align their social media strategies with the online behavior of the consumers. This is study; mainly focused to understand the influence of Facebook fashion retailers’ brand page and purchase intention among the Sri Lankan Face book users. Objectives of this research were to understand the influence of engaging on Facebook brand page on purchase intention for fashion retail in Sri Lanka, therefore the researcher has investigated main construct of Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) of the Facebook brand page and their relationship with both Attitude towards Brand (ATB) and Purchase Intention respectively. Finally, to see whether there is a mediating effect of Attitude towards Brand on the relationship between PU and Purchase Intention and PEOU and Purchase Intension respectively. The review is based on the theoretical rationale and supportive empirical findings. A descriptive statistical review is presented to reasoning why fashion industry is considered as a context to be examined whilst empirical evidences are presented to support the arguments. The paper concludes with research propositions to examine how Facebook Brand Page make an influence on Consumer Purchase Intention.

Unexpected dynamics is detected deep in the Tomonaga-Luttinger spin liquid regime. Close to the point where the system is half-magnetized (and believed to be equivalent to a gapless easy plane chain in zero field) we observed orientation-dependent spin gap and anomalous $g$-factor values. Field theoretical analysis demonstrates that the observed low-energy excitation modes in magnetized (C$_{5}$H$_{12}$N)$_{2}$CuBr$_{4}$ are solitonic excitations caused by Dzyaloshinskii-Moriya interaction presence.

description: Japan imports 6.3 MMT of wheat annually and consumes almost 35 percent of this in the form of noodles. The purpose of this paper is to report on a study that evaluates the preferences of Japanese millers for the various characteristics of wheat and flour that are used in noodle making in Japan. The study used stated preference methodologies (SPM), that were developed and pre-tested through initial interviews with Japanese flour millers. In total, 57 purchase and quality managers for 22 Japanese milling companies were surveyed by means of direct interviews and 41 respondents completed the full SPM survey. Multinomial logit models of millers' preferences were developed and tested and the parameter estimates of these are reported in the paper. This elicited their choices of wheat and flour with alternative combinations of characteristics, at specified levels, for various wheat classes and noodle flours. Data were also collected on stated choices for wheat sourced from different origins. Millers prefer wheat with test weights of minimum 80, dockage below 0.4 percent and falling numbers above 250. Preferences for protein, ash and color were specific for different wheat classes and for use in different noodle flours. Millers also display a preference for amylograph at minimum of 400 BU for noodle flour. For hard wheat millers preferred wheat of U.S. and Canadian origin, but for semi-hard and medium wheat, they preferred Australian origin wheat. These results may assist wheat breeders and traders in exporting nations in marketing their products and positioning these in this important and premium wheat market.

description: This study examines the willingness to pay for a locally-produced, natural beef product in the Intermountain West. In addition to presenting market shares at various prices, this study examines the relevance of several production characteristics, to determine how important they are to consumers, especially the target group willing to pay premium prices. Concern about hormones is consistently higher than other animal- and environmentally-friendly attributes, while concern about local production is the lowest among the respondents. As would be expected, the average concern about each of these characteristics increased among the group most willing to pay a premium for natural beef.

description: We have investigated a number of globular cluster candidates from a recent wide-field study by Harris et al. (2004a) of the giant elliptical galaxy NGC 5128. We used the Magellan I telescope + MagIC camera under excellent seeing (0.3"-0.6") and obtained very high resolution images for a sample of 44 candidates. Our images allow us to study the light profiles of the likely clusters. This is the first ground-based study of structural parameters for globular clusters outside the Local Group. We compare the psf-deconvolved profiles with King models and derive structural parameters, ellipticities and surface brightnesses. In general, our clusters are similar in size, ellipticity, core radius and central surface brightness to their counterparts in other galaxies, in particular those in NGC 5128 observed with HST by Harris et al. (2002). However, they extend to higher ellipticities and larger half-light radii than their Galactic counterparts. Combining our results with those of Harris et al. fills in the gaps previously existing in $r_h - M_V$ parameter space and indicates that any substantial difference between presumed distinct cluster types in this diagram, including for example the Faint Fuzzies of Larsen & Brodie (2000) and the `extended, luminous' M31 clusters of Huxor et al. (2005) is now removed and that clusters form a continuum in this diagram. Indeed, this continuum now extends to the realm of the Ultra Compact Dwarfs. We have carried out additional analysis to quantify the contamination by background galaxies. This shows that, although galaxies cannot be easily told apart from clusters in some of the structural diagrams, the combination of excellent image quality and Washington photometry should limit the contamination to roughly 10% of the population of cluster candidates.

description: This study quantifies the differential in demand between different USDA quality grades of beef and the interaction between quality graded beef and other meats. We provide estimates of meat retailer own and cross price demand elasticities for USDA Choice and Select boxed beef. Results indicate that meat retailers have more elastic demand for lower quality graded beef. Seasonal analysis indicates demand for both beef quality grades becomes highly price inelastic during the summer "cook-out" months. The two beef quality grades are strong substitutes during the fall and winter. However, Select beef is not a substitute for Choice beef in the spring and summer.

description: This descriptive study examines the reproductive health awareness of 100 randomly selected college students in selected private colleges in Olongapo City. The survey covered six basic and common reproductive health issues: maternal and child health, family planning, promotion of breastfeeding, adolescent reproductive health, prevention and management of abortion, prevention and management of reproductive tract infections. The data were subjected using weighted mean, and Pearson –r. The following information was generated: student-respondents were aware of the six basic and common reproductive health issues. On the sources of students' information, which included socio-economic conditions, status of women, social and gender issues, culture and psycho-social issues, the respondents perceived all of these factors as important. The correlational analysis also revealed a moderate to strong relationship values in all six health issues. The sources of students’ information significantly affected the levels of awareness in the different issues about reproductive health. Moreover, the sources of reproductive health information come from the following according as ranked by the respondents: parents, nurse/ doctor, television, friends, and the internet.

description: Techniques developed for handing inverse-power-law potentials in atomic physics are applied to the tensor one-pion exchange potential to determine the regions in which it can be treated perturbatively. In S-, P- and D-waves the critical values of the relative momentum are less than or of the order of 400 MeV. The RG is then used to determine the power counting for short-range interaction in the presence of this potential. In the P-and D-waves, where there are no low-energy bound or virtual states, these interactions have half-integer RG eigenvalues and are substantially promoted relative to naive expectations. These results are independent of whether the tensor force is attractive or repulsive. In the 3S1 channel the leading term is relevant, but it is demoted by half an order compared to the counting for the effective-range expansion with only a short-range potential. The tensor force can be treated perturbatively in those F-waves and above that do not couple to P- or D-waves. The corresponding power counting is the usual one given by naive dimensional analysis.

description: We discuss the extended X-ray emission seen in three archival Chandra observations, and one archival XMM-Newton observation, of the FRII radio galaxy Pictor A. The overall properties of the X-ray lobes are consistent with the conclusions of earlier workers that the extended X-ray emission is largely due to the inverse-Compton process, and the implied departure from equipartition is in the range seen by us in other sources. In detail, we show that the X-ray/radio flux ratio varies quite strongly as a function of position throughout the source, and we discuss possible implications of this observation for the spatial variation of electron energy spectra and magnetic field strength through the lobe. We show that the radio and X-ray properties of the lobe are not consistent with a simple model in which variations in the magnetic field strength alone are responsible for the observed differences between emission at different frequencies. We also discuss the origins of the extended emission seen around the eastern hotspot, arguing that it may be diffuse synchrotron radiation tracing a region of distributed particle acceleration, and the implications of a possible weak X-ray counterjet detection which, taken together with the other properties of the bright X-ray jet, leads us to suggest that the X-ray jet and possible counterjet are also produced by synchrotron emission.

Correlation Effects and Structural Dynamics in the $β$-Pyrochlore Superconductor KOs$_{2}$O$_{6}$

description: Electronic, magnetic, and dynamical properties of the new superconducting $β$-pyrochlore KOs$_2$O$_6$ and related RbOs$_2$O$_6$ and CsOs$_2$O$_6$ compounds are calculated and compared with experiment and contrasted with structurally related spinel pyrochlores. The calculated susceptibility Stoner enhancement (110%) and thermal mass enhancement $λ$ = 2.5-3 reflect moderate but perhaps important Coulomb correlations. The K$^{+}$ ion optic mode is found to be unstable, allowing large excursions of 0.5-0.6 Åfrom its ideal site of the K ion along $<111>$ directions. This dynamical mode is much less anharmonic in the isostructural Rb and Cs compounds (with larger cations), perhaps accounting for their progressively lower values of T$_c$. Electron scattering from this very anharmonic mode may be the cause of the anomalous concave-downward resistivity that is seen only in KOs$_2$O$_6$.

description: We observed a field in the disk of the LMC on two consecutive nights in search of rapid variable stars. We have found two pulsating stars of type RRab and delta Sct, and four binary stars, among the latter one sdB or CV below the LMC blue Main Sequence and three very close binary systems on the MS. At least one of the MS binaries, and possibly all three, are the first solar-type (W UMa-type) contact binaries to be detected in any extragalactic system and observed to obey the same Mv = Mv(log P, B-V) calibration as the Galactic systems. Given the selection effects due to small amplitudes at faint magnitudes, the frequency of such binaries in the disk of the LMC with its large spread in population ages is not inconsistent with that in the disk of our Galaxy, and contrasts with the lack of binaries found in earlier observations of the much younger LMC cluster LW55.

description: A multi--cluster model of traffic flow is studied, in which the motion of cars is described by a stochastic master equation. Assuming that the escape rate from a cluster depends only on the cluster size, the dynamics of the model is directly mapped to the mathematically well-studied zero-range process. Knowledge of the asymptotic behaviour of the transition rates for large clusters allows us to apply an established criterion for phase separation in one-dimensional driven systems. The distribution over cluster sizes in our zero-range model is given by a one--step master equation in one dimension. It provides an approximate mean--field dynamics, which, however, leads to the exact stationary state. Based on this equation, we have calculated the critical density at which phase separation takes place. We have shown that within a certain range of densities above the critical value a metastable homogeneous state exists before coarsening sets in. Within this approach we have estimated the critical cluster size and the mean nucleation time for a condensate in a large system. The metastablity in the zero-range process is reflected in a metastable branch of the fundamental flux--density diagram of traffic flow. Our work thus provides a possible analytical description of traffic jam formation as well as important insight into condensation in the zero-range process.

description: We study the effects of superfluidity on the monopole and quadrupole collective excitations of a dilute ultra-cold Fermi gas with an attractive interatomic interaction. The system is treated fully microscopically within the Bogoliubov-de Gennes and quasiparticle random-phase approximation methods. The dependence on the temperature and on the trap frequency is analyzed and systematic comparisons with the corresponding hydrodynamic predictions are presented in order to study the limits of validity of the semiclassical approach.

Why Some Interfaces Cannot be Sharp

description: A central goal of modern materials physics and nanoscience is control of materials and their interfaces to atomic dimensions. For interfaces between polar and non-polar layers, this goal is thwarted by a polar catastrophe that forces an interfacial reconstruction. In traditional semiconductors this reconstruction is achieved by an atomic disordering and stoichiometry change at the interface, but in multivalent oxides a new option is available: if the electrons can move, the atoms don`t have to. Using atomic-scale electron energy loss spectroscopy we find that there is a fundamental asymmetry between ionically and electronically compensated interfaces, both in interfacial sharpness and carrier density. This suggests a general strategy to design sharp interfaces, remove interfacial screening charges, control the band offset, and hence dramatically improving the performance of oxide devices.

description: Hipparcos Intermediate Astrometric Data (IAD) have been used to derive astrometric orbital elements for spectroscopic binaries from the newly released Ninth Catalogue of Spectroscopic Binary Orbits (SB9). Among the 1374 binaries from SB9 which have an HIP entry, 282 have detectable orbital astrometric motion (at the 5% significance level). Among those, only 70 have astrometric orbital elements that are reliably determined (according to specific statistical tests discussed in the paper), and for the first time for 20 systems, representing a 10% increase relative to the 235 DMSA/O systems already present in the Hipparcos Double and Multiple Systems Annex. The detection of the astrometric orbital motion when the Hipparcos IAD are supplemented by the spectroscopic orbital elements is close to 100% for binaries with only one visible component, provided that the period is in the 50 - 1000 d range and the parallax is larger than 5 mas. This result is an interesting testbed to guide the choice of algorithms and statistical tests to be used in the search for astrometric binaries during the forthcoming ESA Gaia mission. Finally, orbital inclinations provided by the present analysis have been used to derive several astrophysical quantities. For instance, 29 among the 70 systems with reliable astrometric orbital elements involve main sequence stars for which the companion mass could be derived. Some interesting conclusions may be drawn from this new set of stellar masses, like the enigmatic nature of the companion to the Hyades F dwarf HIP 20935. This system has a mass ratio of 0.98 but the companion remains elusive.
