Supernova 1987A in the Large Magellanic Cloud presents unprecedented opportunity to observe the evolution of a supernova at all wavelengths. While optical observations with the HST Faint Object Camera have obtained resolutions of 0.1", we are limited in the radio to the resolution obtainable with the Australia Telescope Compact Array (ATCA). ... At this resolution the radio supernova is distinct from a point source, but few physical conclusions can be drawn. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...

... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ... For all possible pairs the probability of trajectory approach at small distances for the epoch, corresponding to the age of the younger pulsar have been evaluated. ...
