Testing models for fully and partially stripped low-mass stars with Gaia: Implications for hot subdwarfs, binary RR Lyrae, and black hole impostors
Pranav Nagarajan, Kareem El-Badry, Alexey Bobrick +4
When low-mass ( ) red giants lose their envelopes to a companion just before the helium flash, the resulting mass transfer can produce binaries hosting hot s…
Volume-limited sample of low-mass red giant stars, the progenitors of hot subdwarf stars II. Sample validation
Diego Benitez-Palacios, Murat Uzundag, Maja Vučković +6
We investigate the progenitors of long-period hot subdwarf B (sdB) binaries, which form when low-mass red giant branch (RGB) stars lose their envelopes through stable Roche lobe ov…
A 500 pc volume-limited sample of hot subluminous stars I. Space density, scale height, and population properties
H. Dawson, S. Geier, U. Heber +25
We present the first volume-limited sample of spectroscopically confirmed hot subluminous stars out to 500 pc, defined using the accurate parallax measurements from the {\em Gaia}…
New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems
P. Bluhm, M. I. Jones, L. Vanzi +10
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orb…
