Abstract

Results from a VLA survey of nearby flare stars are combined with those of other surveys to compare the incidence of radio detection of late-type dwarf stars with other stellar parameters. About 40 percent of known nearby flare stars were detected in the survey. It is found that there is a deficiency of radio detections for M dwarf stars later than dM5.5, in agreement with the falloff in X-ray luminosity of these stars. Evidence is found for a link between radio activity and rotation, because most of the detected sources are stars which are believed to be young disk stars and are still rapid rotators.
