Type I supernovae. I. Analytic solutions for the early part of the light curve
- W. Arnett
- Physics
- 1 February 1982
Analytic solutions for light curves, effective temperatures, and broad-band colors of Type I supernovae are presented. The method is generalized to include effects of finite (large) initial radius…
Foundations of Radiation Hydrodynamics
- D. Mihalas, B. Mihalas, A. Fu, W. Arnett
- Physics
- 31 January 1985
Exposes the great foundation-stones of research on radiating flows in astrophysics. Upon them are built the walls of methodology (some understandably incomplete). Concentration is on fundamentals but…
Analytic solutions for light curves of supernovae of Type II
- W. Arnett
- Physics
- 15 April 1980
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…
The late behavior of supernova 1987A. I - The light curve. II - Gamma-ray transparency of the ejecta
Observations of the late (t = 20-1500 days) bolometric light curve and the gamma-lines and X-rays from supernova 1987A are compared to theoretical models. It is found that 0.073 + or - 0.015 solar…
The Evolution and fate of Very Massive Objects
The structure and evolution of Very Massive Objects (stars of mass approx.10/sup 2/-10/sup 5/ M/sub sun/) are discussed in terms of simple semianalytic models. We estimate the helium enrichment due…
A Microscopic Interpretation of Neutron Star Structure
Neutron star models have been constructed using representative (15) equations of state. The behavior of some of those macroscopic properties which are of observational or evolutionary significance is…
On the theory of type I supernovae.
- W. Arnett
- Physics
- 15 May 1979
A theoretical analysis of the light curves of Type I supernovae is presented. A low-mass helium star (1.5< or approx. =M/sub b//M/sub sun/< or approx. =4), formed by mass transfer in a binary or by…
A possible model of supernovae: Detonation of12C
- W. Arnett
- Physics
- 1 October 1969
Stars of intermediate mass (4M⊙≲M≲9M⊙) may ignite the12C+12C reaction explosively because of the high degree of electron degeneracy in their central regions. After the exhaustion of helium burning in…
