Hipparcos parallaxes for eta Boo and kappa₂ Boo: two successes for asteroseismology

The release of the Hipparcos catalogue provides an opportunity to check results from asteroseismology. Here we show that Hipparcos parallaxes for two stars are in good agreement with oscillation results. For eta Boo, a probable detection of solar-like oscillations by Kjeldsen at al. (1994; astro-ph/9411016) gave a frequency splitting in good agreement with the Hipparcos luminosity. For kappa₂ Boo, a delta Scuti variable, the Hipparcos parallax agrees well with the distance derived by Frandsen et al. (1995).
