MOST,Modes and Models
Abstract
Stellar model analysis of the first successful seismic observations of a star from space are presented. The low frequency radial p-modes of eta Boo observed by MOST (Microvariability and Oscillations of STars) are used to constrain eta Boo's composition, mass, and age. MOST is a micro-satellite specifically designed to observe parts-permillion luminosity variations in bright stars. The MOST data when combined with ground-based observations imply that the outer layers of our standard models of eta Boo are inaccurate.
