Are the compact X-ray sources differentially rotating degenerate dwarfs?
Abstract
Many compact X-ray sources have been found to be members of close binaries. A class of models in which the X-ray source is taken to be a differentially rotating, degenerate dwarf is discussed. Such an object may be a natural result of stellar evolution in close binaries. Variants of the basic model can account for the different observed types of X-ray sources and provide semi quantitative explanations of the observed X-ray luminosities and of the spinup of the pulsating sources. In addition, the model makes some predictions that render it particularly susceptible to observational test. Subject headings: binaries - black holes - rotation, stellar - X-ray sources
