Asteroseismology of Solar-Type and Red-Giant Stars

Understand

We are entering a golden era for stellar physics driven by satellite and telescope observations of unprecedented quality and scope.

• New insights on stellar evolution and stellar interiors physics are being made possible by asteroseismology, the study of stars by the observation of natural, resonant oscillations.
• Asteroseismology is proving to be particularly significant for the study of solar-type and red-giant stars.
• These stars show rich spectra of solar-like oscillations, which are excited and intrinsically damped by turbulence in the outermost layers of the convective envelopes.
