Abstract
Observations of seven rapidly rotating BY Dra variables, obtained at 6 cm with the D-to-A hybrid array of the VLA on three consecutive days in February, 1986, are reported. The results are presented in tables and graphs (along with data from simple VLA detection observations in 1985 and published optical and X-ray data) and characterized in detail. No strong correlation is found between the radio and optical emission in the one star (BY Dra) detected at more than one session, and the observable microwave emission of the stars is tentatively attributed to flares alone. A weak correlation between the X-ray luminosity and the maximum 6-cm luminosity of dMe stars is inferred, but the evidence is considered insufficient to establish a relationship between surface signs of magnetic activity and nonthermal radio emission.
