Astroseismology @ CfA

Astroseismology is the study of oscillations and pulsations in a star using a collection of observational techniques. These are closely analogous to techniques used in solar structure investigations, and loosely comparable to measuring earth tremors on the Earth. Using these techniques we can indirectly study the interior of stars, and hence develop much better theories for describing stellar atmospheres.

Astroseismology at the Center for Astrophysics is being developed using extensive photometric studies of Ap-type stars. For the first time, the vertical structure of a pulsation mode within a stellar atmosphere has been resolved. This has led to a number of papers on the atmospheric structure of Ap-type stars.
