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…

A targeted search for binary white dwarf pulsars using Gaia and WISE

Ingrid Pelisoli, T. R. Marsh, G. Tovmassian +24

After its discovery in 2016, the white dwarf binary AR Scorpii (AR Sco) remained for several years the only white dwarf system to show pulsed radio emission associated with a fast-…

Searching for new variable white dwarfs: The discovery of the three new pulsating and three new binary systems

Larissa Antunes Amaral, Maja Vučković, 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…

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}…

The double low-mass white dwarf eclipsing binary system J2102-4145 and its possible evolution

Larissa Antunes Amaral, James Munday, Maja Vučković +7

Approximately 150 low-mass white dwarfs, with masses below 0.4Msun, have been discovered. The majority of these low-mass WDs are observed in binary systems as they cannot be formed…

TIC 378898110: A Bright, Short-Period AM CVn Binary in TESS

Matthew J. Green, J. J. Hermes, Brad N. Barlow +22

AM CVn-type systems are ultracompact, helium-accreting binary systems which are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong G…
