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…
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…
