X-ray hardness ratios for stars of different spectral types

  • E. J. A. Meurs (a1), P. Casey (a1) and L. Norci (a2)

Abstract

A substantial number of stars was detected in the ROSAT All Sky Survey. Analysis of these data indicates a systematic shift in the distribution of their X-ray hardness ratios, from late type dwarfs to late type giants to early type stars, that can be attributed to systematic differences in line-of-sight absorption.
