Cosmic Rays and High-Energy Neutrinos from Gamma-Ray Bursts

C. D. Dermer, A. Atoyan

Several lines of evidence point to a relationship between gamma-ray bursts (GRBs) and the high mass stars that explode as supernovae. Arguments that GRB sources accelerate cosmic r…

Analysis of a Very Massive DA White Dwarf via the Trigonometric Parallax and Spectroscopic Methods

C. C. Dahn, P. Bergeron, J. Liebert +2

By two different methods, we show that LHS 4033 is an extremely massive white dwarf near its likely upper mass limit for destruction by unstable electron captures. From the accurat…
