The HR Diagram for Normal Radio Stars

  • Conference paper

Part of the book series: Astrophysics and Space Science Library ((ASSL,volume 116))

Abstract

It is found that nonthermal radio emission is associated with stars in very specific locations on the HR diagram. The four classes of objects are typified by early-type mass-loss stars (05/WR), late-type giants and supergiants (M2II), subgiant K-stars (KO IV–III), and flare stars (dMe). The members of each class exhibit about the same maximum radio luminosities, log (LR/Lbol), and flaring timescales, spectra, and polarizations. Membership in a binary system is not found to be a necessary condition for detectable nonthermal emission.

Visiting Fellwo (1983–1984) at the Joint Institute for Laboratory Astrophysics, Boulder, CO. JILA is orerated by the U. of Colorado and the National Bureau of Standards.
