Abstract:
ROSAT All Sky Survey (RASS). The combination results in 836 eclipsing
binaries that display coronal activity and is the largest sample of
active binary stars assembled to date. By using the (V-I) colors of
the ASAS eclipsing binary catalog, we are able to determine the
distances and thus bolometric luminosities for the majority of
eclipsing binaries that display significant stellar activity.
