15000 Ellipsoidal Binary Candidates in TESS: Orbital Periods, Binary Fraction, and Tertiary Companions
Matthew J. Green, Dan Maoz, Tsevi Mazeh +5
We present a homogeneously-selected sample of 15779 candidate binary systems with main sequence primary stars and orbital periods shorter than 5 days. The targets were selected fro…
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…
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…
The Detection of Transiting Exoplanets by Gaia
Aviad Panahi, Shay Zucker, Gisella Clementini +14
Context: The space telescope Gaia is dedicated mainly to performing high-precision astrometry, but also spectroscopy and epoch photometry which can be used to study various types o…
fBLS -- a fast-folding BLS algorithm
Sahar Shahaf, Barak Zackay, Tsevi Mazeh +2
We present fBLS -- a novel fast-folding technique to search for transiting planets, based on the fast-folding algorithm (FFA), which is extensively used in pulsar astronomy. For a…
