Shock Stagnation and Neutrino Losses in Stellar Collapsee. Hydrodynamic calculations of different research groups are now converging on the result that the shock falters before ejecting the mantle and stagnates into a stationary accretion shock (cf. W. Hillebrandt’s review, this volume). A prompt supernova explosion by shock ejection is thereby prevented

Gravitational Radiation from Collapsing Rotating Stellar Cores9) have increased the demand for reliable theoretical calculations of gravitational radiation from all possible energetic astrophysical sources. Among all potential observed sources, supernovae, possessing highly asymmetric cores and being situated in our own galaxy (see the review by Thorne 1980),

Theoretical Models of Type I Supernovaenambiguous as we would desire. Indeed the discussion at the meeting showed that there could be considerable disagreement as to which constraints were the strongest and which could be assigned lower weight. Here the argunents and their various caveats will be presented and readers will be invited to

The Origin of the Crab Nebula and Electron Capture Supernova of 8–10 MƟ Starsbula are only consistent with a presupernova model of the star whose main-sequence mass was M. = 8–9.5 M.. More massive stars contain too much carbon in the helium layer and smaller mass stars do not leave neutron stars. The progenitor star of the Crab Nebula lost an appreciable part of the hydrogen

Carbon-Oxygen White Dwarf Presupernova Modelstion of the star’s core are included, in particular carbon-oxygen separation. Different degrees of chemical differentiation and a wide range of accretion rates are studied. We determine the pre-flash configurations and we show that a variety of results are possible, ranging from total collapse to pa

The Nature of Supernovae as Determined from Their Light Curveseneral to include both types I and II. Many aspects of the models are quantitatively compared with observations. An improved version of the distance and mass independent relation between gamma ray flux and observed apparent magnitude is given. Preliminary results for cosmological distance determinat

Type II Supernovae Photospheres and Distanceseres of Type II supernovae is outlined. The results of a perturbed gray-body calculation are presented to indicate qualitatively some of the important features to be expected. It is found that if the contribution of scattering to the opacity is greater than that of true absorption (as seems likely),

Type I Supernovae — Observational Constraintspectra of the SN I of 1981 in NGC 4536 establishes that elements other than nickel, iron, and cobalt are represented in the maximum-light spectrum, and that permitted Fe II lines are present 17 days later. For models which power the light-curve peak by radioactivity, the lower limits on the mass of
