White-Dwarf Asteroseismology With the Kepler Space Telescope
Frontiers in Astronomy and Space Sciences, 2020 In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

Asteroseismic study of solar-like stars: A method of estimating stellar age [PDF]
, 2008 Asteroseismology, as a tool to use the indirect information contained in stellar oscillations to probe the stellar interiors, is an active field of research presently.

Structure and Evolution of Low-Mass Stars: An Overview and Some Open Problems [PDF]
, 2007 A review is presented of some of the ingredients, assumptions and techniques that are used in the computation of the structure and evolution of low-mass stars. Emphasis is placed on several ingredients which are still subject to considerable uncertainty.

The Power of Asteroseismology for Early Stellar Evolution
Frontiers in Astronomy and Space Sciences, 2019 Stars are the building blocks of planetary systems, clusters, associations, and galaxies. The evolution of stars is driven by physical processes in their interiors making theory of stellar interior structure and evolution an important ingredient of ...

Turbulence in Stellar Interiors [PDF]
International Astronomical Union Colloquium, 1993 AbstractThis review focusses on the most recent work which has been achieved concerning turbulence in stellar interiors. Among all possible causes for such turbulence, the most powerful is certainly the convective instability in unstably stratified regions, but little was known until now beyond the fact that thermal convection is capable of ...

Unveiling the Structure and Dynamics of Red Giants With Asteroseismology
Frontiers in Astronomy and Space Sciences, 2020 The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed

Bayesian analysis of interiors of HD 219134b, Kepler-10b, Kepler-93b, CoRoT-7b, 55 Cnc e, and HD 97658b using stellar abundance proxies [PDF]
, 2016 Using a generalized Bayesian inference method, we aim to explore the possible interior structures of six selected exoplanets for which planetary mass and radius measurements are available in addition to stellar host abundances: HD~219134b, Kepler-10b ...

A generalized bayesian inference method for constraining the interiors of super Earths and sub-Neptunes [PDF]
, 2016 We aim to present a generalized Bayesian inference method for constraining interiors of super Earths and sub-Neptunes. Our methodology succeeds in quantifying the degeneracy and correlation of structural parameters for high dimensional parameter spaces ...

Probing the Interiors of Very Hot Jupiters Using Transit Light Curves [PDF]
, 2009 Accurately understanding the interior structure of extra-solar planets is critical for inferring their formation and evolution. The internal density distribution of a planet has a direct effect on the star-planet orbit through the gravitational ...
