A combined radio and X-ray observation of Algol.
Abstract
The detection of Algol (Beta Per) at 1.4 GHz is reported. The eclipsing phase of Algol has been observed in radio and at X-ray energies. The radio emission is explained as synchrotron radiation from electrons with energies of about 1 MeV. The magnetic field strength is of the order of tens of Gauss. The radio and X-ray emission are cospatial but the energy in the radio component is 1,000,000 times smaller than that of the X-ray component. The simultaneous observation indicates that an energetic particle component can be present in a quiescent X-ray emitting corona.
