Abstract

HEAO-B (Einstein) satellite measurements with the Imaging Proportional Counter revealed the W UMa binary system TZ Bootis as an X-ray source. It is estimated that the luminosity ratioL x/Lvof this system is about 10−3.8 indicating that TZ Bootis is in the transition region between A- and W-type W UMa systems.
