Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Features of Gaia DR3 Spectroscopic Binaries I. Tidal circularization of Main-Sequence Stars
Dolev Bashi, Tsevi Mazeh, Simchon Faigler
Previous studies pointed out that many observed samples of short-period binaries display a cutoff period, , such that almost all binaries with periods shorter than $P_…
A red giant orbiting a black hole
Kareem El-Badry, Hans-Walter Rix, Yvette Cendes +18
We report spectroscopic and photometric follow-up of a dormant black hole (BH) candidate from Gaia DR3. The system, which we call Gaia BH2, contains a red giant a…
Triage of the Gaia DR3 astrometric orbits. I. A sample of binaries with probable compact companions
Sahar Shahaf, Dolev Bashi, Tsevi Mazeh +4
In preparation for the release of the astrometric orbits of Gaia, Shahaf et al. (2019) proposed a triage technique to identify astrometric binaries with compact companions based on…
Gaia Spectroscopic Orbits Validated with LAMOST and GALAH Radial Velocities
Dolev Bashi, Sahar Shahaf, Tsevi Mazeh +5
The recently published Gaia DR3 catalog of 181327 spectroscopic binaries (SB) includes the Keplerian elements of each orbit but not the measured radial velocities (RVs) and their e…
Exoplanets in the Galactic context: Planet occurrence rates in the thin disk, thick disk and stellar halo of Kepler stars
Dolev Bashi, Shay Zucker
In order to gain a better understanding of planet formation and evolution, it is important to examine the statistics of exoplanets in the Galactic context. By combining information…
