By suitable tranformations, primarily made to remove homologous expansion, the partial differential equations describing a Type II supernova are reduced to the time-dependent diffusion equation. The behavior of luminosity, effective temperature, B--V color, and fluid velocity is explicitly presented, with dependence on mass, energy of explosion, initial radius, and opacity shown. The solutions allow crude estimates of the mass of ejected matter (Mapprox. =8 M/sub sun/) and of /sup 56/Co… 
A semianalytical light curve model and its application to type IIP supernovae
The aim of this work is to present a semianalytical light curve model code that can be used for estimating physical properties of core collapse supernovae (SNe) in a quick and efficient way. To
Generalized Semi-analytical Models of Supernova Light Curves
We present generalized supernova (SN) light curve (LC) models for a variety of power inputs including the previously proposed ideas of radioactive decay of {sup 56}Ni and {sup 56}Co and magnetar
The Physics of Type Ia Supernova Light Curves. I. Analytic Results and Time Dependence
We develop an analytic solution of the radiation transport problem for Type Ia supernovae (SNe Ia) and show that it reproduces bolometric light curves produced by more detailed calculations under the
Light Curves of Exploding Wolf-Rayet Stars
The removal of the extended hydrogen envelope surrounding the dense core of preexplosive stars by stellar winds or mass transfer onto a companion star, obviously, has consequences on the optical
The Nature of Supernovae as Determined from Their Light Curves
What are supernovae? An analysis of the probable nature of supernovae is carried through systematically using analytic models which are sufficiently general to include both types I and II. Many
The early rise of Type IIP supernovae (SN IIP) provides important information for constraining the properties of their progenitors. This can, in turn, be compared to pre-explosion imaging constraints
An emerging coherent picture of red supergiant supernova explosions
Three lines of evidence indicate that in the most common type of core collapse supernovae, the energy deposited in the ejecta by the exploding core is approximately proportional to the progenitor
Time Dependence and the Opacity of Type Ia SupernovÆ
The practice of computing theoretical light curves and spectra from models for Type Ia supernova (Sne la) explosions has advanced considerably in the past few years (see the papers by Eastman, by
Hydrodynamical models of type II plateau supernovae
We present bolometric light curves of Type II plateau supernovae obtained using a newly developed, one-dimensional Lagrangian hydrodynamic code with flux-limited radiation diffusion. Using our code
Theoretical light curves for deflagration models of Type Ia supernova
Aims. We present synthetic bolometric and broad-band UBVRI light curves of SNe Ia for four selected 3D deflagration models of thermonuclear supernovae. Methods. The light curves are computed with the
