Circumstellar matter of SN1987A and soft X-ray emission

Nature, 1988
X-ray emission from supernova 1987A has been observed continually by the Ginga satellite since July 1987. The observed X-ray spectrum1,2 has two components: hard X-rays, above 15 keV in energy, have a nearly flat spectrum, and are thought to be Compton-degraded γ-rays from the decay of 56Co (ref. 3); the soft component (

Circumstellar Matter in Direct Impact Algol Systems

Astrophysics and Space Science, 1995
Full-orbit Hα observations have been analyzed to determine the two-dimensional distribution of the circumstellar gas in the four short-period Algols, U Sge, U CrB, RS Vul, and SW Cyg. In these systems, the gas stream resulting from Roche-lobe overflow directly impacts the mass-gaining star and feeds material into a structure known as a ‘transient ...
