Abstract
The correlation between the coronal X-ray temperature and the magnetic field strength in late-type stars is investigated, based on data prim arily from the ROSAT PSPC. According to the observation, we divide the stars into three groups: single, binary and RS CVn stars. From the sa mple of single stars, we find a clear correlation of the coronal tempe rature with the magnetic field strength. We interpret that result as t he magnetic heating process.
