... 1994: . As a result of comparing the spectra of active solar regions from the observations with high spatial resolution in the microwave range at the RATAN-600 (the S-component) with a flare component observed at meter wavelengths on the VLA (USA) we revealed the presence of a strong and prolonged noise storm exactly where a weak decaying active region (with the presence of powerful active regions in the disk) is located. ...

Detection of X-ray Emission from the PSR 1259-63/SS2883 Binary System . ... Abstract Non-pulsed but variable X-ray emission has been detected from the binary system containing the radio pulsar PSR 1259-63 during two pointed ROSAT observations, taken five months apart. This 47.7 ms radio pulsar is in a highly eccentric (e~0.85) binary system with the 10-15 Msun Be-star SS2883. ... The system may be the progenitor of the more slowly rotating Be X-ray binary pulsar systems. simonj@physics.usyd.edu.au ...

... The most important consequence of orbital eccentricity for the evolution of rotators can be understood without detailed calculations, and suggests the existence of two different types of binary systems separated by a critical eccentricity, (Gnusareva and Lipunov, 1985)[ 56 ]). ... Therefore, for a small part of its life the rotator will be in a mixed EP-state, being in the propeller state at periastron and at the ejector state close to apastron. ...

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. ...
