摘要
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 eta Bootis. We show, by direct application, how the p-model frequencies and stellar seismological tools aid in constraining the physical parameters of eta Boo. We confirm the existence of mode bumping and discuss how it may be used to refine the estimate of eta Boo's age. We describe the effect of the new OPAL equation-of-state tables (Rogers, Swenson, and Iglesias) on the p-mode frequencies.
