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 …

Asteroseismology across the Hertzsprung–Russell diagram

DW Kurtz - Annual Review of Astronomy and Astrophysics, 2022 - annualreviews.org
Asteroseismology has grown from its beginnings three decades ago to a mature field
teeming with discoveries and applications. This phenomenal growth has been enabled by …

Evolutionary and pulsational properties of white dwarf stars

LG Althaus, AH Córsico, J Isern… - The Astronomy and …, 2010 - Springer
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 …

White dwarf rotation as a function of mass and a dichotomy of mode line widths: Kepler observations of 27 pulsating DA white dwarfs through K2 campaign 8

JJ Hermes, BT Gänsicke, SD Kawaler… - The Astrophysical …, 2017 - iopscience.iop.org
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 …

Pulsating white dwarf stars and precision asteroseismology

DE Winget, SO Kepler - Annu. Rev. Astron. Astrophys., 2008 - annualreviews.org
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 …

The pulsating white dwarf stars

G Fontaine, P Brassard - … of the Astronomical Society of the …, 2008 - iopscience.iop.org
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≃ …

Accretion and diffusion in white dwarfs-New diffusion timescales and applications to GD 362 and G 29-38

D Koester - Astronomy & Astrophysics, 2009 - aanda.org
Context. A number of cool white dwarfs with metal traces, of spectral types DAZ, DBZ, and
DZ have been found to exhibit infrared excess radiation due to circumstellar dust. The origin …

A unifying explanation of complex frequency spectra of γ Dor, SPB and Be stars: combination frequencies and highly non-sinusoidal light curves

DW Kurtz, H Shibahashi, SJ Murphy… - Monthly Notices of …, 2015 - academic.oup.com
Abstract There are many Slowly Pulsating B (SPB) stars and γ Dor stars in the Kepler
mission data set. The light curves of these pulsating stars have been classified …

Toward ensemble asteroseismology of ZZ Ceti stars with fully evolutionary models

AD Romero, AH Córsico, LG Althaus… - Monthly Notices of …, 2012 - academic.oup.com
ZZ Ceti stars form the most numerous group of degenerate variable stars. They are
otherwise normal DA (H-rich atmospheres) white dwarfs that exhibit pulsations. Here, we …

Seismic Cartography of White-Dwarf Interiors From the Toulouse-Montréal Optimal-Design Approach

N Giammichele, S Charpinet… - Frontiers in Astronomy and …, 2022 - frontiersin.org
Probing internal properties of white-dwarf stars has been amongst the earliest objectives of
asteroseismology, following the first discovery in the late 1960s of non-radial pulsations in …
