    Notes: Abstract The study of radio emission from cataclysmic variables (CVs) is a new and developing field. Radio emission from novae, recurrent novae, dwart novae and each of the subclasses (AM Her and DQ Her) of magnetic CVs have now been reported and are reviewed here. These observations are shown to provide, in general, a probe of the structure of the CV on length scales typically ≳1011 cm. Radiation mechanisms, both incoherent and coherent, relevant to the observed radio emission are also discussed. These suggest that the red dwarf in AM Her and DQ Her is also magnetized and provides support for theories for the evolution of CVs which require a magnetized secondary star.

    Notes: Abstract Multiband observations of the AM Herculis-type binary CW1103+254 show significant circular polarization (∼13%) in the J band. Recently, a model with high temperature (kT∼20 keV) and small dimensionless plasma parameter (∧∼104) was suggested for the emitting region. However, it gives negligible polarization in the J band. In this paper, a method, in which the J band polarization and the peak frequency ν⋆ of the spectrum are taken into account, is used to determine T and ∧. For the viewing angle θ=80° and the magnetic field B=30MG, we find that kT=5.0 keV and ∧=106. The temperature of the emitting region is close to the value (kT=8.7 keV) derived for the region emitting cyclotron lines in VV Puppis. If these radiations arise from the post-shock regions, then these temperatures are significantly lower than those predicted by standard accretion models or the shock structure is inhomogenous and more complex than previously assumed.

    Notes: Abstract A number of models have been proposed for the observed cosmic gamma-ray bursts. A class of such models involves the use of magnetic energy as the principal source of energy required for the bursts. In this case, arguments are presented to show that degenerate stars are favored. Mechanisms for magnetohydrodynamic instabilities in white dwarfs and neutron stars are discussed. Preliminary work indicates that magnetic white dwarfs can (but neutron stars probably cannot) account for many of the observed features of the bursts.

    Notes: [Auszug] Cyg X-3 is a remarkable X-ray source3, emitting X rays of energy ?1 keV, with a luminosity 3 xl038 erg s-1, which are modulated with a 4.8-h period, thought to be the orbital period of the underlying binary-star system (though there is no direct spectroscopic evidence to support this conclusion). ...

    Notes: [Auszug] A remarkable feature of pulsars is that despite their compact sizes (radii jR106cm) their angular momenta are much less than that of their progenitors on the main sequence. Furthermore, they are slow rotators in the sense that u)2R3/GM" 1, where ? is the angular velocity and M == IM its mass. Note ...

    Notes: [Auszug] SIRá€"Lindley1 states that the report2 3 of a half-millisecond pulsar in the remnant of supernova 1987A "has surprised everybody and could, if confirmed, stand theory on its head". He has apparently overlooked several papers (refs 4 and 5, for example) suggesting that pulsars may ...
