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 VuÄkoviÄ +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…
