Supernovae and Their Remnants [PDF]

open access: possible, 1988
Supernovas can be divided into two distinct classes on the basis of their spectra. Supernovae of type I (SNI) exhibit no hydrogen lines whereas those of type II (SNII) do show hydrogen lines in their spectra. Historically (Baade 1958) SNI have, with the usual perversity of astronomical nomenclature, been assigned to Population II and SNII to Population

Supernovae and Supernova Remnants

1983
Supernovae are the result of explosions which terminate the life of massive stars. The amount of energy released by the supernovae in our galaxy is so large that these explosions provide the dominant energy for the heating of the hot (T ≳ 106 K) IS component and for the kinetic energy of the large scale motions of the interstellar clouds.

Abundances in supernova remnants

AIP Conference Proceedings, 1984
This paper outlines the abundances one may expect to observe as the result of an explosion of the evolved star that is the progenitor of a supernova. (AIP)

Galactic supernova remnants

Space Science Reviews, 1985
A progress report is given on our current interpretation of the X-ray emission from supernova remnants. Previous results from earlier experiments, the Einstein Observatory in particular, are reviewed and supplemented by the most recent data from the Exosat mission for a selection of remnants (Puppis-A, Cas-A, SN 1006, RCW103, W49B).

Supernovae and Their Remnants

1974
Supernovae of type II must be related to rather massive stars. They appear to occur rather exclusively in the spiral arms of galaxies and this fact alone sets a lower limit of about 5 M⊙ to their main sequence mass. If we believe that all massive stars above some critical value become supernovae (and none below this value) the supernova rate would ...
