Stellar Stalling: the view from asteroseismology [PDF]

, 2023
Asteroseismology, the study of intrinsic oscillations in stars, can reveal fundamental properties of cool stars critical in our understanding of stellar rotational evolution.

Looking into dark matter with asteroseismology

Frontiers in Astronomy and Space Sciences, 2022
Dark matter remains as an elusive component of modern Cosmology. According to previous research, stellar physics observables can be affected by the presence of hypothetical dark matter particles, which can be produced or accreted into the stars.

Asteroseismology [PDF]

, 2013
Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior

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

Frontiers in Astronomy and Space Sciences, 2022
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 these evolved compact stars.

Ensemble asteroseismology

Astronomy & Astrophysics
Context. Solar-like oscillations have to date been observed in hundreds of main-sequence and sub-giant stars. However, only a select number of detections have been made in K-type dwarfs, using extreme-precision ground-based radial velocity observations ...

Photometric Stellar Parameters for Asteroseismology and Galactic Studies

, 2014
Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars.

Kepler Asteroseismology Program: Introduction and First Results [PDF]

, 2010
Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observations of normal modes of oscillation.

Recent Progress in Asteroseismology [PDF]

Symposium - International Astronomical Union, 2001
Asteroseismology, the study of stellar interiors on the basis of observations of multi-mode stellar oscillations, extends over a large part of the Hertzsprung-Russell diagram. The recently discovered EC14026 stars promise information about the properties of stars on the horizontal branch.

Asteroseismology of Compact Stars

Universe
Compact stars have been perceived as natural laboratories of matter at an extremely high density. The uncertainties of the equation of state (EOS) of matter can be constrained by observing compact stars.
