Supernovae and Their Remnants [PDF]

, 1987
Supernovae (SNe) and supernova remnants (SNRs) represent an important area of research in astrophysics because they are central to our understanding of such diverse fields as the late stages of stellar evolution, mass loss from late-type stars, nucleosynthesis, and interstellar medium processes and abundances. In addition, they provide a laboratory for

Supernovae and supernova remnants [PDF]

, 2001
A supernova explosion is among the most dramatic events that can be seen. The term ‘supernova’ is somewhat misleading, as such an event represents not a new star (that is, a ‘nova’), but instead the end of a star’s life. Nuclear fusion, the energy source of the stars, creates heavier elements from lighter elements.

Supernovae and Their Remnants [PDF]

, 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.

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).
