ABSTRACT

Radio emission has been detected from stars in various stages of their stellar evolution. Earlier detections of stellar radio emission were either from more evolved stars with very extended atmospheres, from young stars blowing powerful winds, or from stars with much more intense magnetic activity than the Sun. The Sun has been known to be a source of radio emission since 1942. Its radio emission was first detected as interference with radar being used by England during the Second World War. Radio emission can also be detected from some flare stars even when they are not flaring. Young stars, formed or still forming, frequently present radio emission. One mechanism often mentioned to produce the radio emission is curvature radiation. All supernova remnants can be a significant source of radio emission. The remnant neutron stars are rapidly rotating and produce one of the most remarkable radio emitting stellar objects — pulsars.
