Query: Hipparcos parallaxes for eta Boo and kappa_2 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 kappa_2 Boo, a delta Scuti variable, the Hipparcos
parallax agrees well with the distance derived by Frandsen et al. (1995).
