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…
Where are the binaries? -- Searching for blue horizontal-branch stars in binary systems in the inner Galactic Halo
R. Culpan, M. Dorsch, I. Pelisoli +14
Blue horizontal-branch (BHB) stars are evolved low-mass objects that have completed their core hydrogen burning main-sequence (MS) stage and have lost significant mass during the r…
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…
