The Nature and Origins of Sub-Neptune Size Planets. [PDF]
J Geophys Res Planets, 2021 Abstract Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet surveys over the last quarter century. Results from NASA's Kepler mission have revealed a bimodality in the radius distribution of these objects, with a relative

Asteroseismology of Compact Stars
UniverseCompact 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.

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 ...

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).

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 and interferometry [PDF]
The Astronomy and Astrophysics Review, 2007 Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community ...

Hipparcos Luminosities and Asteroseismology [PDF]
Highlights of Astronomy, 2000 AbstractAsteroseismology involves using the resonant frequencies of a star to infer details about its internal structure and evolutionary state. Large efforts have been made and continue to be made to measure oscillation frequencies with both ground- and space-based telescopes, with typical precisions of one part in 103–104.
