HATSouth is the world's first network of automated and homogeneous telescopes that is
capable of year-round 24 hr monitoring of positions over an entire hemisphere of the sky …

We report on the spectroscopic confirmation of 68 new bright (G= 13.5–17.2 mag) and blue
(pre-) white dwarfs (WDs). This finding has allowed us to almost double the number of the …

The discovery in 1998 of a pulsating white dwarf in the cataclysmic variable GW Lib opened
up a new avenue of exploration in the asteroseismology of white dwarfs. Since dwarf novae …

Context. Pulsation frequencies reveal the interior structures of white dwarf stars, shedding
light on the properties of these compact objects that represent the final evolutionary stage of …

White dwarf WD 1145+ 017 is orbited by several clouds of dust, possibly emanating from
actively disintegrating bodies. These dust clouds reveal themselves through deep, broad …

With space missions such as Kepler, TESS, and Gaia, we have a wealth of data on pulsating
white dwarfs that can be leveraged in white dwarf asteroseismology. We address the …

The standard theory of pulsations deals with the frequencies and growth rates of
infinitesimal perturbations in a stellar model. Modes that are calculated to be linearly driven …

We report the discovery of the second pulsating hydrogen-rich (DA) white dwarf in the
Kepler field, KIC 11911480. It was selected from the Kepler-INT Survey (KIS) on the basis of …

We report on the analysis of 34 years of photometric observations of the pulsating helium
atmosphere white dwarf GD358. The complete data set includes archival data from 1982 to …

We aimed at collecting all known white dwarf pulsators with hydrogen-dominated
atmospheres and list their main photometric and atmospheric parameters together with their …
