An upper limit on the frequency of short-period black hole companions to Sun-like stars
Matthew J. Green, Yoav Ziv, Hans-Walter Rix +9
Stellar-mass black holes descend from high-mass stars, most of which had stellar binary companions. However, the number of those binary systems that survive the binary evolution an…
A generative model for Gaia astrometric orbit catalogs: selection functions for binary stars, giant planets, and compact object companions
Kareem El-Badry, Casey Lam, Berry Holl +4
Astrometry from Gaia DR3 has produced a sample of 170,000 Keplerian orbital solutions, with many more anticipated in the next few years. These data have enormous potential to…
Gaia BH1 and BH2 -- evolutionary models with overshooting of the black hole progenitors within the present-day binary separation
Avishai Gilkis, Tsevi Mazeh
Three black holes (BHs) in wide binaries - Gaia BH1, BH2 and BH3 - were recently discovered. The likely progenitors of the BHs were massive stars that experienced a supergiant phas…
HighSpec: A High-Resolution Spectrograph for the MAST Telescope Array
Yahel Sofer Rimalt, Sagi Ben-Ami, Eran Ofek +13
We present the updated design of HighSpec, a high-resolution spectrograph designed for the Multi Aperture Spectroscopic Telescope (MAST). HighSpec offers…
Different Planetary Eccentricity-Period (PEP) Distributions of Small- and Giant-Planets
Dolev Bashi, Tsevi Mazeh, Simchon Faigler
We used the database of short-period ( days) exoplanets radial-velocity (RV) orbits to study the planetary eccentricity-period (PEP) distribution. We first d…
Wide Binary Orbits are Preferentially Aligned with the Orbits of Small Planets, but Probably Not Hot Jupiters
Sam Christian, Andrew Vanderburg, Juliette Becker +28
Studying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 AU) can shed light on how planets form and evolv…
