StaNdaRT: A repository of standardized test models and outputs for supernova radiative transfer
Stéphane Blondin, Sergei Blinnikov, Fionntan P. Callan +26
We present the first results of a comprehensive supernova (SN) radiative-transfer (RT) code-comparison initiative (StaNdaRT), where the emission from the same set of standardized t…
Binarity and beyond in A stars I. Survey description and first results of VLTI/GRAVITY observations of VAST targets with high Gaia-Hipparcos accelerations
Idel Waisberg, Ygal Klein, Boaz Katz
A-stars are the progenitors of about half of the white dwarfs (WDs) that currently exist. The connection between the multiplicity of A-stars and that of WDs is not known and the ob…
Beyond binarity in A stars II. Disentangling the four stars in the vicinity of the triple HIP 87813 within the quintuple system HJ2814
Idel Waisberg, Ygal Klein, Boaz Katz
A-stars are the progenitors of about half of the white dwarfs (WDs) that currently exist. The connection between the multiplicity of A-stars and that of WDs is not known and both m…
A Simple Random-Walk Model Explains the Disruption Process of Hierarchical, Eccentric 3-Body Systems
Jonathan Mushkin, Boaz Katz
We study the disruption process of hierarchical 3-body systems with bodies of comparable mass. Such systems have long survival times that vary by orders of magnitude depending on t…
Extreme close approaches in hierarchical triple systems with comparable masses
Niv Haim, Boaz Katz
We study close approaches in hierarchical triple systems with comparable masses using full N-body simulations, motivated by a recent model for type Ia supernovae involving direct c…
The Way To a Double Degenerate: per cent of Stars have a Companion
Ygal Klein, Boaz Katz
We find that per cent of A-type stars or red giants are bound with a massive companion () in an intermediate wide orbit ($0.5<P<5000\mb…
Luminosity function suggests up to 100 white dwarfs within 20 pc may be hiding in multiple systems
Boaz Katz, Subo Dong, Doron Kushnir
We examine the luminosity function of white dwarfs (WDs) in the local ``complete'' WD sample ( pc) of Holberg et. al. 2008. We find that the fraction of bright and young WDs…
OGLE-LMC-ECL-11893: The discovery of a long-period eclipsing binary with a circumstellar disk
Subo Dong, Boaz Katz, Jose L. Prieto +10
We report the serendipitous discovery of a disk-eclipse system OGLE-LMC-ECL-11893. The eclipse occurs with a period of 468 days, a duration of about 15 days and a deep (up to ΔI ~1…
The rate of WD-WD head-on collisions may be as high as the SNe Ia rate
Boaz Katz, Subo Dong
We show that a White Dwarf-White Dwarf (WD-WD) binary with semi-major axis a=1-300 AU, which is orbited by a stellar mass outer perturber with a moderate pericenter r_{p, out} \sim…
Exploring a Stream of Highly-Eccentric Binaries with Kepler
Subo Dong, Boaz Katz, Aristotle Socrates
With 16-month Kepler data, 14 long-period (40 d - 265 d) eclipsing binaries on highly eccentric orbits (minimum e between 0.5 and 0.85) are recognized from their closely separated…
