Asteroseismology [PDF]

, 2012
Asteroseismology is the determination of the interior structures of stars by using their oscillations as seismic waves. Simple explanations of the astrophysical background and some basic theoretical considerations needed in this rapidly evolving field ...

Prospects for asteroseismology [PDF]

Astrophysics and Space Science, 2009
The observational basis for asteroseismology is being dramatically strengthened, through more than two years of data from the CoRoT satellite, the flood of data coming from the Kepler mission and, in the slightly longer term, from dedicated ground-based ...

An overview of helio- and asteroseismology [PDF]

Symposium - International Astronomical Union, 1988
The purpose of the present paper is to give an introduction to the nomenclature, and a few of the results, of helio- and asteroseismology. It is hoped that this may provide a useful background for the more specialized reviews, and the contributed papers, in these proceedings.

Helio-and asteroseismology [PDF]

Proceedings of the International Astronomical Union, 2001
AbstractObservations of solar and stellar oscillations are providing detailed information about stellar interiors. In the case of the Sun the set of observed frequencies is sufficiently detailed and accurate that the properties of the solar interior, such as sound speed, density and internal rotation, can be inferred with substantial precision and ...

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.

A calibration point for stellar evolution from massive star asteroseismology [PDF]

Nature Astronomy, 2023
Transiting Exoplanet Survey Satellite data of the massive star HD 192575 reveal pulsation frequencies that allow the inference of its convective core mass and interior rotation profile, thus providing a calibration point for interior chemical and angular

Asteroseismology of Planetary Nuclei [PDF]

Symposium - International Astronomical Union, 1997
The first two pulsating planetary-nebula nuclei (PNNs), those of K 1-16 and Lo 4, were discovered by Grauer & Bond (1984) and Bond & Meakes (1990). They are nonradial multiperiodic g-mode pulsators, with typical periods near 25–31 min and low amplitudes (up to ∼ 0.05–0.1 mag).

Internal magnetic fields in 13 red giants detected by asteroseismology [PDF]

Astronomy & Astrophysics, 2023
While surface fields have been measured for stars across the HR diagram, internal magnetic fields remain largely unknown. The recent seismic detection of magnetic fields in the cores of several Kepler red giants has opened a new avenue to understand ...

The Potential of Asteroseismology to Resolve the Blue Supergiant Problem [PDF]

Astrophysical Journal Letters, 2023
Despite major progress in our understanding of massive stars, concerning discrepancies still remain between observations and theory. Most notable are the numerous stars observed beyond the theoretical main sequence, an evolutionary phase expected to be ...
