Gaia's promise to detect compact-object binaries: where we stand with the third data release
Chirag Chawla, Sourav Chatterjee, Katelyn Breivik
With its third data release (DR3), Gaia begins unveiling dormant candidate compact object (CO) binaries with luminous companions (LC) as predicted by several past theoretical studi…
Realistic predictions for Gaia black hole discoveries: comparison of isolated binary and dynamical formation models
Pranav Nagarajan, Kareem El-Badry, Chirag Chawla +6
Astrometry from Gaia has enabled discovery of three dormant black holes (BHs) in au-scale binaries. Numerous models have been proposed to explain their formation, including several…
Detecting Detached Black Hole binaries through Photometric Variability
Chirag Chawla, Sourav Chatterjee, Neev Shah +1
Understanding the connection between the properties of black holes (BHs) and their progenitors is interesting in many branches of astrophysics. Discovering BHs in detached orbits w…
Dynamically Forming Extremely Low-Mass White Dwarf Binaries in Wide Orbits
Ambreesh Khurana, Chirag Chawla, Sourav Chatterjee
The detection of a 0.2 Msun extremely low-mass white dwarf (EW) in a wide orbit (Porb about 450 days) with a 1.1 Msun main-sequence (MS) companion, KIC 8145411, challenges our curr…
Weighing the Darkness II: Astrometric Measurement of Partial Orbits with Gaia
Jeff J. Andrews, Katelyn Breivik, Chirag Chawla +2
Over the course of several years, stars trace helical trajectories as they traverse across the sky due to the combined effects of proper motion and parallax. It is well known that…
Gaia May Detect Hundreds of Well-characterised Stellar Black Holes
Chirag Chawla, Sourav Chatterjee, Katelyn Breivik +3
Detection of black holes (BHs) with detached luminous companions (LCs) can be instrumental in connecting the BH properties with their progenitors' since the latter can be inferred…
