To the interpretation of the astron observations of flares of the star EV Lac.
Abstract
Observations of EV Lac obtained with the Astron astrophysical observatory are analyzed. An emission measure of about 3 x 10 to the 50th/cu cm was found for the faint-glow region in the C IV lines, which is close to the value for the flare transition region. It appears that Astron observed the formation of a radiative shock wave accompanying explosive vaporization of the chromosphere.
