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…

Searching for new variable white dwarfs: The discovery of the three new pulsating and three new binary systems
Larissa Antunes Amaral, Maja VuÄkoviÄ, Ingrid Pelisoli +3
In recent years, approximately 150 low-mass white dwarfs (WDs), typically with masses below 0.4 solar masses, have been discovered. Observational evidence indicates that most of th…
