Probing the interior physics of stars through asteroseismology
C Aerts - Reviews of Modern Physics, 2021 - APS
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 …

Evolutionary and pulsational properties of white dwarf stars
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 …

Magnetic fields in isolated and interacting white dwarfs
L Ferrario, D Wickramasinghe, A Kawka - Advances in Space Research, 2020 - Elsevier
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 …
