A Sun-like star orbiting a black hole
Kareem El-Badry, Hans-Walter Rix, Eliot Quataert +18
We report discovery of a bright, nearby () Sun-like star orbiting a dark object. We identified the system as a black hole candidate via its astrometri…
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…
Gaia Data Release 3. Summary of the variability processing and analysis
L. Eyer, M. Audard, B. Holl +55
Context. Gaia has been in operations since 2014. The third Gaia data release expands from the early data release (EDR3) in 2020 by providing 34 months of multi-epoch observations t…
Gaia Data Release 3: Ellipsoidal Variables with Possible Black-Hole or Neutron Star secondaries
R. Gomel, T. Mazeh, S. Faigler +10
As part of Gaia Data Release 3, supervised classification identified a large number of ellipsoidal variables, for which the periodic variability is presumably induced by tidal inte…
Probable Dormant Neutron Star in a Short-Period Binary System
Tsevi Mazeh, Simchon Faigler, Dolev Bashi +24
We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a…
