Stellar hydrodynamics caught in the act: Asteroseismology with CoRoT and Kepler

TL;DR

This paper reviews how asteroseismology using CoRoT and Kepler data reveals new insights into stellar interiors, including convection, rotation, and dynamic phenomena across different star types.

Contribution

It highlights the novel application of space-based asteroseismology to study stellar interior dynamics and their impact on stellar evolution.

Findings

Convection zones and mixing processes are better characterized.

Stellar rotation effects are observed in oscillation data.

Dynamic behaviors of stellar oscillations are identified across various stars.

Abstract

Asteroseismic investigations, particularly based on data on stellar oscillations from the CoRoT and Kepler space missions, are providing unique possibilities for investigating the properties of stellar interiors. This constitutes entirely new ways to study the effects of dynamic phenomena on stellar structure and evolution. Important examples are the extent of convection zones and the associated mixing and the direct and indirect effects of stellar rotation. In addition, the stellar oscillations themselves show very interesting dynamic behaviour. Here we discuss examples of the results obtained from such investigations, across the Hertzsprung-Russell diagram.
