The discovery of a hot stellar wind.
Abstract
High-resolution 6 cm observations of two early-type stars have been made with the Very Large Array. Cyg OB2 No. 12 appears to have a normal wind with a temperature of about 5000 K; Cyg OB2 No. 9 has unusual and unexpected radio properties which imply that its radio-emitting circumstellar gas is hotter than 300,000 K.
