Yearslong time series of high-precision brightness measurements have been assembled for
thousands of stars with telescopes operating in space. Such data have allowed astronomers …

Understanding massive stars is essential for a variety of branches of astronomy including
galaxy and star cluster evolution, nucleosynthesis and supernovae, pulsars, and black …

We present a novel method to detect variable astrophysical objects and transient
phenomena using anomalous excess scatter in repeated measurements from public …

White dwarf stars are the final evolutionary stage of the vast majority of stars, including our
Sun. Since the coolest white dwarfs are very old objects, the present population of white …

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 …

We present photometry and spectroscopy for 27 pulsating hydrogen-atmosphere white
dwarfs (DAVs; aka ZZ Ceti stars) observed by the Kepler space telescope up to K2 …

▪ Abstract Helioseismology has transformed our knowledge of the Sun's rotation. Earlier
studies revealed the Sun's surface rotation, but now a detailed observational picture has …

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 …

We present a summary of what is currently known about the three distinct families of isolated
pulsating white dwarfs. These are the GW Vir stars (He/C/O-atmosphere stars with T eff≃ …

The magnetic white dwarfs (MWDs) are found either isolated or in interacting binaries. The
isolated MWDs divide into two groups: a high field group (10 5–10 9 G) comprising some …
