Stars are extremely important astronomical objects that constitute the pillars on which the
Universe is built, and as such, their study has gained increasing interest over the years …

Galactic history is written in the white dwarf stars. Their surface properties hint at interiors
composed of matter under extreme conditions. In the forty years since their discovery …

Context. The fast classification of new variable stars is an important step in making them
available for further research. Selection of science targets from large databases is much …

We report detailed follow-up observations of the cataclysmic variable HS 2331+ 3905,
identified as an emission-line object in the Hamburg Quasar Survey. An orbital period of …

Context. The recent arrival of continuous photometric observations of unprecedented quality
from space missions has strongly promoted the study of pulsating stars and caused great …

We calculate and explore an extensive adiabatic model grid for pulsating white dwarfs with
hydrogen-dominated atmospheres, the ZZ Ceti stars. We also compared the computed …

PG 1159-035 is the prototype of the PG 1159 hot (pre-) white dwarf pulsators. This important
object was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence …

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 …

The detection of g-mode pulsations in accreting white dwarfs (WDs) in cataclysmic variables
(CVs) with a large range of effective temperatures (T eff) has shown these WDs to be a more …

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 …
