ROSAT OBSERVATIONS OF PSR 0355+54 and PSR 1642--03 1 Patrick Slane Harvard­Smithsonian Center for Astrophysics 60 Garden Street, Cambridge, MA 02138 USA ABSTRACT PSR 0355+54 and PSR 1642--03 are both radio pulsars whose X­ray behavior was left unresolved by Einstein observations. 1;2 In each case, faint emission was detected near the sources, but appeared to be concentrated 1--2 arcmin from the known pulsar positions. ...

Close binary systems of the RS CVn and Algol type are characterized by a highly variable radio emission, from typical flux densities of a few mJy during low-activity (quiescent) periods, up to 1 Jy during strong flares. The origin of this radio emission is attributed to the gyrosynchrotron mechanism. Several observations of these stars have shown an evolution of the radio spectrum during both the rising and decay phases of flares. ...

In the literature, there is an ambiguity pertaining to the existance of a far-IR excess in RS CVn systems. ... We found 72 acceptable detections in the 12mu band, and 40 in the 25mu band (50% more than the IRAS Point Source Catalog). ... Furthermore, at the higher wavelength bands the IRAS angular resolution drops from 0.5 arcmin at 12mu to 2 arcmin at 100mu and the background becomes very complex so one cannot be certain about the origin of the observed flux. ...
