Scientific paper

Kjeldsen et al. recently obtained strong evidence for solar-like oscillations in the G0 IV star eta Boo. Here we present evolution calculations for the star and compare them with the observed oscillation frequencies. Models can be found that are consistent with the star's luminosity and effective temperature and with the large and small frequency separations. The calculations indicate that dipolar (l = 1) oscillations behaving like gravity modes in the interior of the star can be excited to observable amplitudes; the observations may show evidence for such modes.
