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…
The BlackGEM telescope array I: Overview
Paul J. Groot, S. Bloemen, P. Vreeswijk +75
The main science aim of the BlackGEM array is to detect optical counterparts to gravitational wave mergers. Additionally, the array will perform a set of synoptic surveys to detect…
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…
V838 Mon: A slow waking up of Sleeping Beauty?
T. Liimets, I. Kolka, M. Kraus +15
Context. V838 Monocerotis is a peculiar binary that underwent an immense stellar explosion in 2002, leaving behind an expanding cool supergiant and a hot B3V companion. Five years…
Discovery of 74 new bright ZZ Ceti stars in the first three years of TESS
A. D. Romero, S. O. Kepler, J. J. Hermes +17
We report the discovery of 74 new pulsating DA white dwarf stars, or ZZ Cetis, from the data obtained by the Transiting Exoplanet Survey Satellite (TESS) mission, from Sectors 1 to…
White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 16
S. O. Kepler, Detlev Koester, Ingrid Pelisoli +2
White dwarfs are the end state of the evolution of more than 97% of all stars, and therefore carry information on the structure and evolution of the Galaxy through their luminosity…
Ground based observation of ZZ Ceti stars and the discovery of four new variables
Alejandra D. Romero, L. Antunes Amaral, T. Klippel +7
We perform ground based photometric observations of 22 DA white dwarf stars, 10 already known ZZ Cetis and 12 candidates with atmospheric parameters inside the classical instabilit…
White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 14
S. O. Kepler, Ingrid Pelisoli, Detlev Koester +6
White dwarfs carry information on the structure and evolution of the Galaxy, especially through their luminosity function and initial-to-final mass relation. Very cool white dwarfs…
A Study of Cool White Dwarfs in the Sloan Digital Sky Survey Data Release 12
G. Ourique, A. D. Romero, S. O. Kepler +2
In this work we study white dwarfs where to compare the differences in the cooling of DAs and non-DAs and their f…
New white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12
S. O. Kepler, Ingrid Pelisoli, Detlev Koester +7
We report the discovery of 6576 new spectroscopically confirmed white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12. We obtain Teff, log g and mass for h…
