A New Equation of State for Dense Hydrogen–Helium Mixtures
Authors: Chabrier G. , Mazevet S. , Soubiran F. 
Published: February 2019

Abstract
We present a new equation of state (EOS) for dense hydrogen/helium mixtures that covers a range of densities from 10−8 to

, pressures from 10−9 to 1013 GPa, and temperatures from 102 to 108 K. The calculations combine the EOS of Saumon, Chabrier & van Horn in the low-density, low-temperature molecular/atomic domain, the EOS of Chabrier & Potekhin in the high-density, high-temperature fully ionized domain, the limits of which differ for H and He, and ab initio quantum molecular dynamics calculations in the regime of intermediate density and temperature, characteristic of pressure dissociation and ionization. The EOS for the H/He mixture is based on the so-called additive volume law and thus does not take into account the interactions between the two species. A major improvement of the present calculations over existing ones is that we calculate the entropy over the entire density–temperature domain, a necessary quantity for calculations of stellar or planetary evolution. The EOS results are compared with existing experimental data, namely Hugoniot shock experiments for pure H and He, and with first-principles numerical simulations for both the single elements and the mixture. This new EOS covers a wide range of physical and astrophysical conditions, from Jovian planets to solar-type stars, and recovers the existing relativistic EOS at very high densities, in the domains of white dwarfs and neutron stars. All the tables are made publicly available.

Abstract
The large Integral Field Spectroscopy surveys have allowed the classification of ionizing sources of emission lines on sub-kiloparsec scales. In this work, we define two non-parametric parameters, quiescence (F

q
) and its concentration (C

q
), to quantify the strength and the spatial distribution of the quenched areas, respectively, traced by the LI(N)ER regions with low EW(Hα). With these two measurements, we classify MaNGA galaxies into inside-out and outside-in quenching types according to their locations on the F

q
versus C

q
plane and we measure the fraction of inside-out (outside-in) quenching galaxies as a function of halo mass. We find that the fraction of galaxies showing inside-out quenching increases with halo mass, irrespective of stellar mass or galaxy type (satellites versus centrals). In addition, high-stellar-mass galaxies exhibit a greater fraction of inside-out quenching compared to low-stellar-mass ones in all environments. In contrast, the fraction of outside-in quenching does not depend on halo mass. Our results suggest that morphological quenching may be responsible for the inside-out quenching seen in all environments. On the other hand, the flat dependence of the outside-in quenching on halo mass could be a mixed result of ram pressure stripping and galaxy mergers. Nevertheless, for a given environment and stellar mass, the fraction of inside-out quenching is systematically greater than that of outside-in quenching, suggesting that inside-out quenching is the dominant quenching mode in all environments.

Abstract
Herein, we present 12CO (J = 1–0) and 13CO (J = 1–0) emission-line observations via the FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45 m telescope (FUGIN) toward Spitzer bubble N4. We observed clouds at three discrete velocities: 16, 19, and 25 km s−1. Their masses were 0.1 × 104
M
⊙, 0.3 × 104
M
⊙, and 1.4 × 104
M
⊙, respectively. The distribution of the 25 km s−1 cloud likely traces the ring-like structure observed at mid-infrared wavelength. The 16 and 19 km s−1 clouds have not been recognized in previous observations of molecular lines. We could not find clear expanding motion of the molecular gas in N4. On the contrary, we found a bridge feature and a complementary distribution, which are discussed as observational signatures of a cloud–cloud collision (CCC), between the 16 and 25 km s−1 clouds. We proposed a possible scenario wherein the formation of a massive star in N4 was triggered by a collision between the two clouds. The timescale of collision is estimated to be 0.2–0.3 Myr, which is comparable to the estimated dynamical age of the H ii region of ∼0.4 Myr. In N4W, a star-forming clump located west of N4, we observed molecular outflows from young stellar objects and the observational signature of a CCC. Thus, we also proposed a possible scenario in which massive- or intermediate-mass star formation was triggered via a CCC in N4W.

Published: February 2019

Abstract
The X-ray symbiotic (SyXB) V934 Her = 4U 1700+24 is an M giant–neutron star (NS) binary system. Employing optical and infrared radial velocities spanning 29 yr combined with the extensive velocities in the literature, we compute the spectroscopic orbit of the M giant in that system. We determine an orbital period of 4391 days, or 12.0 yr, the longest for any SyXB and far longer than the 404 day orbit commonly cited for this system in the literature. In addition to the 12.0 yr orbital period, we find a shorter period of 420 days, similar to the one previously found. Instead of orbital motion, we attribute this much shorter period to long secondary pulsation of the M3 III SRb variable. Our new orbit supports earlier work that concluded that the orbit is seen nearly pole-on, which is why X-ray pulsations associated with the NS have not been detected. We estimate an orbital inclination of 11.°3 ± 0.°4. Arguments are made that this low inclination supports a pulsation origin for the 420 day secondary period. We also measure the CNO and Fe peak abundances of the M giant and find it to be slightly metal-poor compared to the Sun, with no trace of the NS-forming supernova event. The basic properties of the M giant and NS are derived. We discuss the possible evolutionary paths that this system has taken to get to its current state.

Abstract
We present the first optical spectroscopy of five confirmed (or strong candidate) redback millisecond pulsar binaries, obtaining complete radial velocity curves for each companion star. The properties of these millisecond pulsar binaries with low-mass, hydrogen-rich companions are discussed in the context of the 14 confirmed and 10 candidate field redbacks. We find that the neutron stars in redbacks have a median mass of 1.78 ± 0.09 M
⊙ with a dispersion of σ = 0.21 ± 0.09. Neutron stars with masses in excess of 2 M
⊙ are consistent with, but not firmly demanded by, current observations. Redback companions have median masses of 0.36 ± 0.04 M
⊙ with a scatter of σ = 0.15 ± 0.04 M
⊙, and a tail possibly extending up to 0.7–0.9 M
⊙. Candidate redbacks tend to have higher companion masses than confirmed redbacks, suggesting a possible selection bias against the detection of radio pulsations in these more massive candidate systems. The distribution of companion masses between redbacks and the less massive black widows continues to be strongly bimodal, which is an important constraint on evolutionary models for these systems. Among redbacks, the median efficiency of converting the pulsar spin-down energy to γ-ray luminosity is ∼10%.
Multiple Stellar Populations of Globular Clusters from Homogeneous Ca-CN Photometry. IV. Toward Precision Populational Tagging*
Authors: Lee Jae-Woo 
Published: February 2019

Abstract
Apparently similar but multifaceted photometric systems are currently being used to investigate the multiple stellar populations in globular clusters (GCs), without the concrete general agreement on the definition of the multiple populations. In recent years, an attractive idea of utilization of the widely used UBI photometry, C

UBI
, for the populational tagging of the giant stars in GCs has emerged. We perform a critical analysis of the

and C

UBI
indices, finding that the populational tagging from the C

UBI
index may not be reliable, due to the inherited trait of the broadband photometry. As a consequence, the populational number ratios and the cumulative radial distributions from the C

UBI
index can be easily in error. The results for M3, which shows a very strong radial gradient in the populational number ratio, highlight the strengths of our

index: both the Hubble Space Telescope imaging and the ground-based spectroscopy failed to grasp the correct picture, which can be easily achieved with our

index with small-aperture ground-based telescopes, due to the small field of view or crowdedness in the central part of the cluster.
Magnetic Turbulence Spectra and Intermittency in the Heliosheath and in the Local Interstellar Medium
Authors: Fraternale Federico , Pogorelov Nikolai V. , Richardson John D. , Tordella Daniela 
Published: February 2019

Abstract
The understanding of inertial-scale dynamics in the heliosheath is not yet thorough. Magnetic field fluctuations across the inner heliosheath (IHS) and the local interstellar medium (LISM) are here considered to provide accurate and highly resolved statistics over different plasma conditions between 88 and 136 au. By using the unique in situ 48 s measurements from the Voyager Interstellar Mission, we investigate different fluctuation regimes at the magnetohydrodynamic (MHD) scales, down to the MHD-to-kinetic transition. We focus on a range of scales exceeding five frequency decades (5 × 10−8 < f < 10−2 Hz), which is unprecedented in literature analysis. A set of magnetic field data for eight intervals in the IHS, in both unipolar and sector regions, and four intervals in the LISM is used for the analysis. Results are set forth in terms of the power spectral density, spectral compressibility, structure functions, and intermittency of magnetic field increments. In the heliosheath, we identify the energy-injection regime displaying a ∼1/f energy decay, and the inertial-cascade regime. Here, the power spectrum is anisotropic and dominated by compressive modes, with intermittency that can reach kurtosis values of up to 10. In the interstellar medium the structure of turbulence is anisotropic as well, with transverse fluctuations clearly prevailing after 2015 May. Here, we show that intermittent features occur only at scales smaller than 10−6 Hz.

More and more herbaria are digitising their collections. Images of specimens are made available online to facilitate access to them and allow extraction of information from them. Transcription of the data written on specimens is critical for general discoverability and enables incorporation into large aggregated research datasets. Different methods, such as crowdsourcing and artificial intelligence, are being developed to optimise transcription, but herbarium specimens pose difficulties in data extraction for many reasons.
To provide developers of transcription methods with a means of optimisation, we have compiled a benchmark dataset of 1,800 herbarium specimen images with corresponding transcribed data. These images originate from nine different collections and include specimens that reflect the multiple potential obstacles that transcription methods may encounter, such as differences in language, text format (printed or handwritten), specimen age and nomenclatural type status. We are making these specimens available with a Creative Commons Zero licence waiver and with permanent online storage of the data. By doing this, we are minimising the obstacles to the use of these images for transcription training. This benchmark dataset of images may also be used where a defined and documented set of herbarium specimens is needed, such as for the extraction of morphological traits, handwriting recognition and colour analysis of specimens.
Type specimens of Neuropterida in the Hope Entomological Collection, Oxford University Museum of Natural History

Published: February 2019

The Hope Entomological Collection in the Oxford University Museum of Natural History holds a large and diverse array of historically valuable type specimens for species in the superorder Neuropterida (Megaloptera, Neuroptera, and Raphidioptera). Most are from the mid-1800s (1823–1874). Here, we report each type found during a rigorous search of the collection, and we confirm the identity and status of each type with bibliographic, specimen, and label data. Images, current nomenclatural information, and references for name changes are provided for each species.We identified primary or secondary types for 76 species in seven families of Neuroptera, primary and secondary types for one species of Raphidoptera (Raphidiidae), and secondary types for three species of Megaloptera (Corydalidae). Among the Neuroptera, we found primary types for 26 species of Mantispidae, 16 species of Myrmeleontidae, 11 species of Ascalaphidae, seven species of Nemopteridae, five species of Chrysopidae, and one species each of Coniopterygidae and Hemerobiidae. Types for only two species that were reported to be in the collection were not found.To help stabilize the nomenclature, we made new lectotype designations for the following six species in the Hope Collection:ColobopterusdissimilisMcLachlan, 1871;MantispabatesellaWestwood, 1867;MantispamyrapetrellaWestwood, 1867;MantispatropicaWestwood, 1852;MyrmeleonanomalusRambur, 1842; andMyrmeleonsingulareWestwood, 1847. We also made new lectotype designations for two species in the Natural History Museum in London:MantispaindicaWestwood, 1852, andMantispaquadrituberculataWestwood, 1852. In several other cases, holotype determinations in the literature were recognized as lectotype designations. Finally, to correct an important error in the literature, we reinstated the synonymization ofAscalaphusanticusWalker, 1853,A.loquaxWalker, 1853, andA.truxWalker, 1853 underA.longusWalker, 1853.
Invasive Species Removal Promotes Habitat Restoration but Does Not Immediately Improve the Condition of a Threatened Plant Subspecies
Authors: Mattingly Kali Z. , Wiley John J. , Leopold Donald J. 
Published: February 2019

Abstract
Impacts of invasive species on rare species are relevant to conservation. We studied the response of Leedy's roseroot Rhodiola integrifolia subsp. leedyi, a subspecies listed as threatened under the Endangered Species Act, to removal of the invasive species Japanese knotweed Fallopia japonica. Japanese knotweed has invaded the largest known population of Leedy's roseroot, affecting about 10% of all Leedy's roseroot in the world. Japanese knotweed shaded Leedy's roseroot, but the two did not share belowground resources because of their position on cliffs. To study this interaction and, ultimately, to restore Leedy's roseroot habitat to an open, high-light condition, we removed Japanese knotweed in a three-treatment block design. We measured Leedy's roseroot abundance, growth, and reproduction in treatment blocks and in uninvaded areas before and after treatment. Compared with uninvaded areas, Japanese knotweed invasion negatively affected Leedy's roseroot abundance, growth, and reproduction. Light interception by Japanese knotweed degraded the habitat for Leedy's roseroot. Herbicide removal of Japanese knotweed resulted in increased light and temperature compared with untreated invaded plots but did not affect Leedy's roseroot abundance, growth, or reproduction over the 2 y of our study. These results show that invasive species removal is conducive to restoring Leedy's roseroot habitat, but recovery in the subspecies may lag behind restoration of the habitat, suggesting that additional action or time may be required to restore preinvasion performance of Leedy's roseroot. Results of this study may inform restoration efforts for other systems and contribute to the literature on interspecific interactions.
Cinéma, mesure des émotions et diffusion : le docteur Toulouse, le biologiste Cépède et le service scientifique des établissements Pathé frères (1918-1919)
Authors: Cépède Frédéric 
Published: February 2019

En 1909 Charles Pathé intéressé au développement du cinéma scientifique confia à Jean Comandon la direction d’un laboratoire de microcinématographie dans un service dit « Le Scientifique » de son usine de Vincennes. On y réalisa nombre de films de vulgarisation. Après la guerre cet intérêt scientifique s’orienta vers l’analyse des réactions du public face à des images projetées afin d’améliorer le rendement des films en ciblant le type d’images et le meilleur rythme permettant de provoquer les émotions recherchées. Ce sont les docteurs Raoul Mourgue, et Édouard Toulouse qui sont chargés de ces recherches. Le biologiste Casimir Cépède (1882-1954), fondateur en 1918 de l’Institut de biologie appliquée auprès de l’Institut Pasteur, assiste ces derniers. Cet article exploitant des fonds d’archives jusqu’ici inexplorés met en lumière la personnalité de Cépède, son projet d’une psychocinématographie qui serait à la base de l’industrie et de l’exploitation cinématographique. Proposé à Charles Pathé, un Comité scientifique est créé brièvement à cette fin. Les perspectives envisagées vont de la propagande à la pédagogie. À partir de 1924 Cépède se dirige vers le nouveau medium de la radio.
