Analysis of White Dwarfs with Strange-Matter Cores
G. J. Mathews, I. -S. Suh, B. O'Gorman +4
We summarize masses and radii for a number of white dwarfs as deduced from a combination of proper motion studies, Hipparcos parallax distances, effective temperatures, and binary…
Early Star Formation, Nucleosynthesis, and Chemical Evolution in Proto-Galactic Clouds
L. Saleh, T. C. Beers, G. J. Mathews
We present numerical simulations to describe the nucleosynthesis and evolution of pre-Galactic clouds in a model which is motivated by cold dark matter simulations of hierarchical…
White Dwarfs Near Black Holes: A New Paradigm for Type I Supernovae
J. R. Wilson, G. J. Mathews
We present calculations indicating the possibility of a new class of Type I supernovae. In this new paradigm relativistic terms enhance the self gravity of a carbon-oxygen white dw…
Prospects for Constraining Cosmology with the Extragalactic Cosmic Microwave Background Temperature
John M. LoSecco, Grant J. Mathews, Yun Wang
Observers have demonstrated that it is now feasible to measure the cosmic microwave background (CMB) temperature at high redshifts. We explore the possible constraints on cosmology…
Gamma-Ray Bursts via Pair Plasma Fireballs from Heated Neutron Stars
Jay D. Salmonson, James R. Wilson, Grant J. Mathews
In this paper we model the emission from a relativistically expanding electron-positron pair plasma fireball originating near the surface of a heated neutron star. This pair fireba…
Mass-Radius Relation for Magnetic White Dwarfs
In-Saeng Suh, G. J. Mathews
Recently, several white dwarfs with very strong surface magnetic fields have been observed. In this paper we explore the possibility that such stars could have sufficiently strong…
