A giant x-ray flare from a spectroscopic binary system in the Hyades has also been reported (Stern, Antiochos and Underwood 1982).

First of all let me thank all of you for accepting our invitation to attend the Opening Ceremony. Such an impressive gathering of so many distinguished astrophysicists from all over the world is in itself a reward for all of us in the S

The interrelations between these quantities are compared to the results of theoretical investigations for low mass stars. The evolutionary state of flare stars is discussed.

Speicherprogrammierbare Steuerungen. We now have observed a sufficient number of the nearby M-dwarfs to determine an X-ray luminosity function and we have explored the activity and variability of these stars to the extent of observing, for the first time, X-ray flares with simultaneous ground-based optical and IUE ultraviolet coverag

Factors of stellar duplicity are shown to be quite prevalent in presenting the observations. The most luminous X-ray dwarfs below the Sun are strongly

The presence of transition regions and coronae have been inferred from the detection of UV emission lines like NV, CIV, SilV etc. with IUE and X-ray observatio
