Environments and Rates of Supernovaelar progenitors of supernovae, particularly those of Type IIP (SN IIP). The progenitors of SN IIP were red supergiants at the time of explosion; their inferred initial main-sequence masses have ranged from about 8-16 solar masses, with most near the lower end of this range. Supernovae of Types IIP,

Circumstellar Interactionntext of core-collapse supernovae. Hydrodynamic interaction between the supernova ejecta and CSM produced by a wind from the progenitor star leads to a forward shock that accelerates and heats the inner layers of the CSM, a reverse shock that reheats the outer layers of the ejecta, and a thin intera

Supernova Remnantsds of SNRs are known in the Milky Way and nearby galaxies, primarily revealed by their radio and X-ray flux. The discussion outlines the key phases of SNR evolution: early free expansion, the adiabatic or Sedov phase, and the radiative, snowplow phase. The focus then turns to young SNRs in the Galax

Pair-Instability Supernova Modelsn-positron pair production in an offcenter shell. The infalling shell compresses and heats the oxygen core to the point of thermonuclear ignition and explosion of (usually) the entire star. The nominal oxygen core masses and zero-age main-sequence (ZAMS) masses for nonrotating, solar-abundance model

Supernova 1987Aing the blue-supergiant supernova progenitor and the remarkable triple-ring system in the circumstellar environment with which the ejecta interact. The unique detection of neutrinos confirmed the basic model of core collapse. The compact object left behind probably is a neutron star, but there has b
