An H-alpha survey of neglected Vyssotsky Catalog stars

Consideration is given to a significant number of Vyssotsky K- and M-dwarfs that have either no published radial velocity (71 stars), or a velocity based on a single measure (22), or with an uncertaintly greater than 5 km/s (19). An 'in flare' observation of Vys 250A compared to its quiesc...

Zusammenfassung:Consideration is given to a significant number of Vyssotsky K- and M-dwarfs that have either no published radial velocity (71 stars), or a velocity based on a single measure (22), or with an uncertaintly greater than 5 km/s (19). An 'in flare' observation of Vys 250A compared to its quiescent state, and an example of the double-lined phase of Vys 250B are illustrated. Mean values from the observations are given in tabular form. (AIAA)
