A 500 pc volume-limited sample of hot subluminous stars III. The short-period binary population
H. Dawson, M. Dorsch, J. Munday +16
Hot subdwarf stars of spectral types O and B (sdO/B) in binaries form as products of substantial mass loss near the tip of the red giant branch and offer powerful constraints on bi…
A 500 pc volume-limited sample of hot subluminous stars II. Atmospheric parameters, mass distribution, and kinematics
H. Dawson, M. Dorsch, S. Geier +30
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax meas…
VVV-WIT-13: an eruptive young star with cool molecular features
Zhen Guo, Philip Lucas, Sergey N. Yurchenko +27
Here we investigate an infrared eruptive source, identified from the decade-long VISTA Variables in the Via Lactea survey (VVV). We named this target after a group of variable sour…
Ancient, eclipsing, tidally-locked: A blue lurker progenitor in the population of extreme-velocity star candidates
A. Bhat, M. Dorsch, S. Geier +5
Many extreme velocity candidate stars have been found based on \textit{Gaia} astrometry, but need spectroscopic confirmation. We select late-type hypervelocity star (HVS) candidate…
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…
