Scientific paper

The p-mode frequencies recently observed by Kjeldsen and coworkers, along with other observables, are used to determine the mass, age, and helium abundance of η Bootis. We show, by direct application, how the p-model frequencies and stellar seismological tools aid in constraining the physical parameters of η Boo. We confirm the existence of mode bumping and discuss how it may be used to refine the estimate of η Boo's age. We describe the effect of the new OPAL equation-of-state tables (Rogers, Swenson, and Iglesias) on the p-mode frequencies.
