Nucleosynthesis of light elements inside thermally pulsing AGB stars I: the case of intermediate-mass stars

description: The structural and nucleosynthetic evolution of 3, 4, 5, 6 and \mass{7} stars with two metallicities ($Z = 0.005$ and 0.02) has been computed in detail, from the early pre-main sequence phase up to the thermally pulsing (TP) AGB phase or the onset of off-center carbon burning. Typically 10 to 20 thermal pulses have been followed for each TP-AGB object. This homogeneous and quite large set of models allows us to present an overview of the thermal pulse properties as well as of the nucleosynthesis accompanying the TP-AGB phase of intermediate-mass stars. More specifically, after a brief description of the previous evolutionary stages, predictions are given for the isotopic ratios involving C, N, O, Ne, Mg, Al and Si. Also the surface abundances of 7Li, 19F and 23Na are reported. As the asymptotic phase of the thermal pulses has been reached for each star, we also indicate how these abundances will probably evolve until the stars completely loose their envelope, by including the evolution of the nucleosynthesis itself. This article, in its paper form, has been shortened at a level of roughly 60 \% as required by directives coming from the A\&A editors. The complete article (50 pages containing 37 figures) is only available in electronic form at http://gag.observ-gr.fr/liens/starevol/evol.html

High-entropy ejections from magnetized proto-neutron star winds: implications for heavy element nucleosynthesis

description: Although initially thought to be promising for production of the r-process nuclei, standard models of neutrino-heated winds from proto-neutron stars (PNSs) do not reach the requisite neutron-to-seed ratio for production of the lanthanides and actinides. However, the abundance distribution created by the r-, rp-, or $νp$-processes in PNS winds depends sensitively on the entropy and dynamical expansion timescale of the flow, which may be strongly affected by high magnetic fields. Here, we present results from magnetohydrodynamic simulations of non-rotating neutrino-heated PNS winds with strong dipole magnetic fields from $10^{14}-10^{16}$ G, and assess their role in altering the conditions for nucleosynthesis. The strong field forms a closed zone and helmet streamer configuration at the equator, with episodic dynamical mass ejections in toroidal plasmoids. We find dramatically enhanced entropy in these regions and conditions favorable for third-peak r-process nucleosynthesis if the wind is neutron-rich. If instead the wind is proton-rich, the conditions will affect the abundances from the $νp$-process. We quantify the distribution of ejected matter in entropy and dynamical expansion timescale, and the critical magnetic field strength required to affect the entropy. For $B\gtrsim10^{15}$ G, we find that $\gtrsim10^{-6}$ M$_{\odot}$ and up to $\sim10^{-5}$ M$_{\odot}$ of high entropy material is ejected per highly-magnetized neutron star birth in the wind phase, providing a mechanism for prompt heavy element enrichment of the universe. Former binary companions identified within (magnetar-hosting) supernova remnants, the remnants themselves, and runaway stars may exhibit overabundances. We provide a comparison with a semi-analytic model of plasmoid eruption and discuss implications and extensions.

description: We prove that the existence of a Kahler-Einstein metric on a Fano manifold is equivalent to the properness of the energy functionals defined by Bando, Chen, Ding, Mabuchi and Tian on the set of Kahler metrics with positive Ricci curvature. We also prove that these energy functionals are bounded from below on this set if and only if one of them is. This answers two questions raised by X.-X. Chen. As an application, we obtain a new proof of the classical Moser-Trudinger-Onofri inequality on the two-sphere, as well as describe a canonical enlargement of the space of Kahler potentials on which this inequality holds on higher-dimensional Fano Kahler-Einstein manifolds.

description: Low-power, high-speed and bright electrically driven true single-photon sources, which are able to operate at room temperature, are vital for the practical realization of quantum communication networks and optical quantum computations. Color centers in semiconductors are currently the best candidates, however, in spite of their intensive study in the past decade, the behavior of color centers in electrically controlled systems is poorly understood. Here we present a physical model and establish a theoretical approach to address single-photon emission dynamics of electrically pumped color centers, which interprets experimental results. We support our analysis with self-consistent numerical simulations of a single-photon emitting diode based on a single nitrogen-vacancy center in diamond and predict the second-order autocorrelation function and other emission characteristics. Our theoretical findings demonstrate remarkable agreement with the experimental results and pave the way to the understanding of single-electron/single-photon processes in semiconductors.

Towards macroscopic spin and mechanical superposition via Rydberg interaction

description: This paper is a proposal for the generation of many-body entangled state in atomic and mechanical systems. Application of strong Rydberg dressing interaction and fast bifurcation scheme in an ultra-stable Cs lattice clock in this proposal results to a breakthrough in the formation of large cat states. By detailed study of the de-coherence effects using Quantum Jump Monte Carlo approach and considering obstacles in dense ensembles namely level mixing, molecule formation and collective decoherence this proposal predicts the formation of 700 atoms cat state. Dipole coupling between Rydberg atoms and charged cantilevers is proposed for the transfer of the generated superposition to far separated mechanical oscillators.

description: We review the present status of liquid mirror telescopes. Interferometric tests of liquid mirrors (the largest one having a diameter of 2.5 meters ) show excellent optical qualities. The basic technology is now sufficiently reliable that it can be put to work. Indeed, a handful of liquid mirrors have now been built that are used for scientific work. A 3.7-m diameter LMT is presently being built in the new Laval upgraded testing facilities. Construction of the mirror can be followed on the Web site: http://astrosun.phy.ulaval.ca/lmt/lmt- home.html. Finally we address the issue of the field accessible to LMTs equipped with novel optical correctors. Optical design work, and some exploratory laboratory work, indicate that a single LMT should be able to access, with excellent images, small regions anywhere inside fields as large as 45 degrees.

description: Because of the existence of cubic scalar couplings, there are in general nondecoupling effects at tree level in the scalar sector of any theory with two or more very different mass scales. We show this explicitly in the minimal nonsupersymmetric SU(5) model of grand unification. We show also how tree-level decoupling is guaranteed if supersymmetry is imposed. On the other hand, if the gauge symmetry is larger than that of the standard model at the mass scale of supersymmetry breaking, the two-Higgs-doublet structure at the presumably lower electroweak energy scale will be different from that of the minimal supersymmetric standard model, as shown already previuosly in a number od specific examples. We add here one example involving four Higgs doublets.

description: Binary neutron stars mergers that are expected to be the most powerful source of energy in the Universe definitely exist in nature, as is proven by the observed behavior of the Hulse-Taylor binary radio pulsar. Though most of energy in such events is radiated in gravitational waves, there probably exist several mechanisms giving also electromagnetic radiation. We propose a new one, involving a revival of the radio pulsar several orbital cycles before the merger.

description: My mother Beatrice Annie Moles (nee Grundy) was married on her 26th birthday 9 April 1939 which was also Easter Sunday.She and my father John William Moles lived with my maternal grandmother Margaret Grundy (who was a 65 year old widow) at 21 Oswestry Road, New Hinksey, Oxford which my father had just bought with a mortgage. He worked for the Post Office but volunteered for the army and started his service on 1/1/1940.My mother was a skilled book binder and went back to work for Oxford University Press in 1940 having left it when she married. Life was miserable in the war for married women with responsibilities. They had to go to work but also get rationed food and take in evacuees and get food for them too.My grandma did not want child evacuees so the took in a couple who worked for the Civil Service in Oxford. Although the woman wore a wedding ring they suspected that they were not married because the man did not know the date of her birthday. One night when they were out an Air Raid Warden called to complain of a light in the back bedroom. My mother checked and found that it was the glow from an electric wall fire which had been left on. When the couple returned the man said, "Oh I always leave it on in the evenings to warm the bedroom." My mother was furious at this extravagance. Later when food was scarce they complained about getting the same evening meal two days running. After that my mother told them to find accommodation elsewhere!They were replaced by an elderly couple from the Midlands who they got on with far better as they were retired and were sympathetic to the food difficulties. Unfortunately the man, George Perrett died suddenly one evening. His wife was naturally very upset and my mother had to go out in the blackout to find someone to lay out his body.My other was active had an allotment and went to church with my grandmother every Sunday. She even painted the outside of the house. She suspected that a neighbour who cam to advise her was really trying to lookup her skirt!Although she looked back on the war with nostalgia it was a worrying time for married women whose husbands seldom got leave. Also as the war went on seemingly without end their chances of having a family were diminishing even if their marriage did not break up under the strain of separation which in her case it did not.

The Low Column Density Lyman-alpha Forest

Year: 1996
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We develop an analytical method based on the lognormal approximation to compute the column density distribution of the Lyman-alpha forest in the low column density limit. We compute the column density distributions for six different cosmological models and found that the standard, COBE-normalized CDM model cannot fit the observations of the Lyman-alpha forest at z=3. The amplitude of the fluctuations in that model has to be lowered by a factor of almost 3 to match observations. However, the currently viable cosmological models like the lightly tilted COBE-normalized CDM+Lambda model, the CHDM model with 20% neutrinos, and the low-amplitude Standard CDM model are all in agreement with observations, to within the accuracy of our approximation, for the value of the cosmological baryon density at or higher than the old Standard Bing Bang Nucleosynthesis value of 0.0125 for the currently favored value of the ionizing radiation intensity. With the low value for the baryon density inferred by Hogan & Rugers (1996), the models can only marginally match observations.

description: We have investigated the most essential kaonic nucleus "$K^-pp$" as a resonant state of the $\bar{K}NN$-$πΣN$-$πΛN$ coupled channel system using a chiral SU(3)-based $\bar{K}N$ potential. We treat the "$K^-pp$" resonance adequately with a fully coupled-channel complex scaling method (full ccCSM). Self-consistency needs to be considered for the energy dependence of the chiral SU(3)-based potential. In the present study, we propose a simple prescription for the treatment of self-consistency, considering the {\it averaged threshold} and {\it averaged binding energy of mesons}. With this prescription, we have successfully found the self-consistent solutions of the "$K^-pp$" three-body resonance. The results indicate that the "$K^-pp$" system is bound rather shallowly. In particular, when the potential parameters are constrained with the latest $\bar{K}N$ scattering length, the binding energy and half of the mesonic decay width are obtained as $14-50$ MeV and $8-19$ MeV, respectively.

description: At the start of the war in 1939, Jim was 25 years old and Joan was 21. They both came from Prescot near Liverpool, and met at the local tennis club. They were married in Prescot Parish Church in January 1942 just as the last bombs were falling on Liverpool, and moved to St Helens. Joan was trained as a commercial secretary at a Liverpool college. When there was an air raid, which happened with great frequency in those times in Liverpool, Joan and her fellow students would go down into the air raid shelters. Joan subsequently worked as a secretary at the Halifax Building Society in St Helens. As the men who had previously worked at the branch were away fighting, Joan had to help run the branch. Jim was an accountant in St Helens, and told his family in the years after the war, that he did "secret war work in Manchester". As with many of that generation involved in some of the important war work that was classed as secret, and would probably have entailed Jim signing The Official Secrets Act, the exact nature of his work was never divulged and his family would never know what it was he did. Jim was in the Home Guard, stationed in Knowsley Park, Prescot. The main function of the unit was to man the anti-aircraft guns to try to protect Liverpool - a critical job given the Liverpool was the most heavily bombed area of the country, outside London. Around 4,000 people were killed in the Merseyside area during the Blitz. This death toll was second only to London, which suffered over 40,000 by the end of the war.Both Joan's and Jim's fathers were in reserved occupations. James Robinson Sr worked for the BICC in Prescot, mainly making cables. Oswald Dickens worked for the coal board. As both these jobs were of critical value in the war effort and because both were older men, they were not called to serve in any of the armed forces.

description: We introduce and study the problem Ordered Level Planarity which asks for a planar drawing of a graph such that vertices are placed at prescribed positions in the plane and such that every edge is realized as a y-monotone curve. This can be interpreted as a variant of Level Planarity in which the vertices on each level appear in a prescribed total order. We establish a complexity dichotomy with respect to both the maximum degree and the level-width, that is, the maximum number of vertices that share a level. Our study of Ordered Level Planarity is motivated by connections to several other graph drawing problems. Geodesic Planarity asks for a planar drawing of a graph such that vertices are placed at prescribed positions in the plane and such that every edge is realized as a polygonal path composed of line segments with two adjacent directions from a given set $S$ of directions symmetric with respect to the origin. Our results on Ordered Level Planarity imply $NP$-hardness for any $S$ with $|S|\ge 4$ even if the given graph is a matching. Katz, Krug, Rutter and Wolff claimed that for matchings Manhattan Geodesic Planarity, the case where $S$ contains precisely the horizontal and vertical directions, can be solved in polynomial time [GD'09]. Our results imply that this is incorrect unless $P=NP$. Our reduction extends to settle the complexity of the Bi-Monotonicity problem, which was proposed by Fulek, Pelsmajer, Schaefer and Štefankovič. Ordered Level Planarity turns out to be a special case of T-Level Planarity, Clustered Level Planarity and Constrained Level Planarity. Thus, our results strengthen previous hardness results. In particular, our reduction to Clustered Level Planarity generates instances with only two non-trivial clusters. This answers a question posed by Angelini, Da Lozzo, Di Battista, Frati and Roselli.

description: We develop a method to calculate the column density distribution of the Lyman-alpha forest for column densities in the range $10^{12.5} - 10^{14.5} cm^{-2}$. The Zel'dovich approximation, with appropriate smoothing, is used to compute the density and peculiar velocity fields. The effect of the latter on absorption profiles is discussed and it is shown to have little effect on the column density distribution. An approximation is introduced in which the column density distribution is related to a statistic of density peaks (involving its height and first and second derivatives along the line of sight) in real space. We show that the slope of the column density distribution is determined by the temperature-density relation as well as the power spectrum on scales $2 h Mpc^{-1} < k < 20 h Mpc^{-1}$. An expression relating the three is given. We find very good agreement between the column density distribution obtained by applying the Voigt-profile-fitting technique to the output of a full hydrodynamic simulation and that obtained using our approximate method for a test model. This formalism then is applied to study a group of CDM as well as CHDM models. We show that the amplitude of the column density distribution depends on the combination of parameters $(Ω_b h^2)^2 T_0^{-0.7} J_{HI}^{-1}$, which is not well-constrained by independent observations. The slope of the distribution, on the other hand, can be used to distinguish between different models: those with a smaller amplitude and a steeper slope of the power spectrum on small scales give rise to steeper distributions, for the range of column densities we study. Comparison with high resolution Keck data is made.

description: We present the results of a polarimetric study from our new high-sensitivity L-band (0.8--1.7 GHz) observation of Pictor A with the MeerKAT radio telescope. We confirm the presence of the radio jet extending from the nucleus to the western hotspot of this source. Additionally, we show the radio emission expected to be coincident with previously observed X-ray emission in the radio lobes, confirming that the emission mechanism is of inverse Compton origin, as suggested by a previous study. Our spectropolarimetric analysis using the RM-Synthesis technique reveals a relatively uniform mean RM distribution across the lobes of Pictor A, with most lines-of-sight exhibiting single-peaked Faraday spectra. However, a number of the lines-of-sight exhibit single peaked spectra with a wide base or multiple peaks, suggesting the presence of multiple Faraday components or a Faraday thick structure along Pictor A's lines-of-sight. We also confirm the asymmetry in RM variability and depolarization between the two lobes of this source which were reported in a previous study.

We find for the linear collider that the event rate is substantial provided electrons scattered under small angles can be detected, and a measurement of this cross section provides an excellent test of the BFKL Pomeron. For LEP, although the number of events is substantially smaller, an initial study of this process is feasible.

However, many leading methods in machine learning, such as neural networks, require large volumes of training data, may not be interpretable, do not easily include known constraints and symmetries, and often do not generalize beyond the attractor where models are trained. These factors limit the use of these techniques for the online identification of a model in the low-data limit, for example following an abrupt change to the system dynamics. In this work, we extend the recent sparse identification of nonlinear dynamics (SINDY) modeling procedure to include the effects of actuation and demonstrate the ability of these models to enhance the performance of model predictive control (MPC), based on limited, noisy data. SINDY models are parsimonious, identifying the fewest terms in the model needed to explain the data, making them interpretable, generalizable, and reducing the burden of training data. We show that the resulting SINDY-MPC framework has higher performance, requires significantly less data, and is more computationally efficient and robust to noise than neural network models, making it viable for online training and execution in response to rapid changes to the system. SINDY-MPC also shows improved performance over linear data-driven models, although linear models may provide a stopgap until enough data is available for SINDY. SINDY-MPC is demonstrated on a variety of dynamical systems with different challenges, including the chaotic Lorenz system, a simple model for flight control of an F8 aircraft, and an HIV model incorporating drug treatment.

Running Coupling Constant of a Gauge Theory in the Framework of the Schwinger-Dyson Equation: Infrared Behavior of Three-Dimensional Quantum Electrodynamics

description: We discuss how to define and obtain the running coupling of a gauge theory in the approach of the Schwinger-Dyson equation, in order to perform a non-perturbative study of the theory. For this purpose, we introduce the nonlocally generalized gauge fixing into the SD equation, which is used to define the running coupling constant (this method is applicable only to a gauge theory). Some advantages and validity of this approach are exemplified in QED3. This confirms the slowing down of the rate of decrease of the running coupling and the existence of non-trivial infra-red fixed point (in the normal phase) of QED3, claimed recently by Aitchison and Mavromatos, without so many of their approximations. We also argue that the conventional approach is recovered by applying the (inverse) Landau-Khalatnikov transformation to the nonlocal gauge result.

Merger Rate of Equal-Mass Spherical Galaxies

description: We present cross sections and reaction rates for merging to occur during encounters of equal-mass spherical galaxies. As an application, we determine the rate of galaxy merging in clusters of galaxies. We present results for two types of Plummer models (a full and a truncated one), two King models and the Hernquist model. Cross sections are determined on the basis of a large number ($\sim 500$) of simulations of galaxy encounters, using the 10-Gigaflops GRAPE 3A special-purpose computer. We characterize the overall merger rate of galaxies in a galaxy cluster by a single number, derived from our cross sections by an integration over galaxy encounter velocities in the limit of a constant density in velocity space. For small clusters, where the cluster velocity dispersion may not significantly exceed the internal velocity dispersion of the individual galaxies, this constant-density approximation may not be valid. For those cases, we present separate results, based on integrations of our cross sections over Maxwellian velocity distributions. Finally, tidal effects from the cluster potential as well as from neighboring galaxies may prevent a barely bound galaxy pair from spiraling in after their first encounter. We give a quantitative estimate of the resulting reduction in the actual merger rate, due to these tidal interactions.

description: We study the \egg, \egm and \epg decays using an extended three-flavor Nambu-Jona-Lasinio model that includes the 't~Hooft instanton induced interaction. We find that the $η$-meson mass, the \egg, \egm and \epg decay widths are in good agreement with the experimental values when the $U_{A}(1)$ breaking is strong and the flavor $SU(3)$ singlet-octet mixing angle $θ$ is about zero. The calculated $ηγγ^\ast$ transition form factor has somewhat weaker dependence on the squared four-momentum of the virtual photon. The effects of the $U_A(1)$ anomaly on the scalar quark contents in the nucleon, the $Σ_{πN}$ and $Σ_{KN}$ terms and the baryon number one and two systems are also studied.

description: Thomas Burgoyne was born on the 16th of September 1920 in Edinburgh, Scotland. He lived with his parents and three sisters in a flat in a tenement building in the south of the city, leaving school at the age of 14 to become a butcher's apprentice.When war was declared in September 1939, he aspired to become a pilot in the RAF. However, this was not to be as a medical examination revealed him to be colour blind! At the age of 19, he enlisted at RAF Padgate in Cheshire. We know he was stationed in 1941 at RAF Cranage, also in Cheshire, which was set up in August 1939 as a training station and aircraft maintenance unit.As far as we know, he served as a ground wireless operator for most of the war. His service number was 1100970, and he maintained his knowledge of Morse Code throughout the rest of his life.Although he may not have seen active service, he fulfilled an important role in the service of his country. We know that he was popular and made many friends from around the world. He kept the menu card for Christmas Day lunches in 1940 and 1941: it looks like the commanding officer and officers made sure that the men and women were well looked after at Christmas! These cards are covered in signatures and addresses of fellow servicemen and women.Although peace was declared in May 1945, he continued to serve in the RAF for some time after that. He was sent on at least two missions to decommission British aeroplanes which had been abandoned in Europe for one reason or another, more than likely as a result of crashes. We know that he was sent to Burdofass in the north of Norway. There are some photographs of him with other servicemen in the snow. Even coming from Scotland, he would never have experienced such cold weather. It looks like they also found a wreck of at least one German plane with its Swastika still intact.He was also sent to Lyons in France for more decommissioning work and possibly visited Paris at this time also - befriending a French family. He obviously really enjoyed his time in these countries as he kept many photographs and picture postcards of scenes around the cities.Although the war was a difficult time for the world, it certainly offered him opportunities to travel and to meet new people outside of his rather restricted life in Edinburgh. After his discharge, he returned home, where he found it difficult to get a job at first as employers had filled the vacant job positions during the war. However, he did eventually return to his previous employment and went on to live a full and peaceful life until the grand old age of 91!
Post-Collapse evolution of globular clusters

description: A number of globular clusters appear to have undergone core collapse, in the sense that their predicted collapse time is much shorter than their current age. Simulations using gas models and Fokker-Planck approximation have shown that the central density of a globular cluster after the collapse undergoes nonlinear oscillation with large amplitude (gravothermal oscillation). However, whether such an oscillation actually takes place in a real $N$-body system has remained unsolved, because an $N$-body simulation with a sufficiently high resolution would have required the computing resource of the order of several Gflops$\cdot$years. In the present paper, we report the result of such a simulation, performed on a dedicated special-purpose computer GRAPE-4. We simulated the evolution of isolated point-mass systems with up to 32,768 particles. The largest number of particles reported previously is 10,000. We confirmed that gravothermal oscillation takes place in an $N$-body system. The expansion phase shows all signatures that are considered as the evidences of the gravothermal nature of the oscillation. At the maximum expansion, the core radius is $\sim 1$\% of the half-mass radius for the run with 32,768 particles. The maximum core size $r_c$ depends on $N$, as $ \propto N^{-1/3}$.

description: Quantized vortices have been observed in a variety of superfluid systems, from $^4$He to condensates of alkali-metal bosons and ultracold Fermi gases along the BEC-BCS crossover. In this article we study the stability of singly quantized vortex lines in dilute dipolar self-bound droplets. We first discuss the energetic stability region of dipolar vortex excitations within a variational ansatz in the generalized nonlocal Gross-Pitaevskii functional that includes quantum fluctuation corrections. We find a wide region where stationary solutions corresponding to axially-symmetric vortex states exist. However, these singly-charged vortex states are shown to be unstable, either by splitting the droplet in two fragments or by vortex-line instabilities developed from Kelvin-wave excitations. These observations are the results of large-scale fully three-dimensional simulations in real time. We conclude with some experimental considerations for the observation of such states and suggest possible extensions of this work.
