Photometric Variability of Chromospherically Active Stars. I. The Constant Stars
Abstract
Over 3800 differential UBV observations for 15 known or suspected chromospherically active stars are presented. All stars turned out to exhibit no light variations over the period of observation from 1983 through 1987. Three additional nonactive stars already known to be constant have been used to determine the external and internal precision of the data.
