Asteroseismology and the Solar-Stellar Connection

Travis Metcalfe (NCAR)

By monitoring the 5-minute oscillations through an entire solar cycle,
the SOHO mission has provided an unprecedented view of the interaction
between helioseismology and magnetic activity. The Kepler satellite
will soon establish a broader context for our understanding of this
interaction by documenting solar-like oscillations in hundreds of
Sun-like stars, in some cases during a significant fraction of the
stellar activity cycle. I will give an overview of the information
about stellar structure and dynamics that is already emerging from
asteroseismology, and how it might lead to a deeper understanding of
global magnetic changes in the Sun. As a proof of concept I will
describe some recent work using a solar-like model for the
pulsation-activity interaction, applied to the "future Sun" beta
Hydri.
