On the Masses of X-Ray Sources

Abstract

An analysis of X-ray sources based on the Roche model is here presented. On this basis we can conclude that pulsating sources appear to have systematically smaller masses than nonpulsating sources. We suggest identifying the first objects as neutron stars and the second as totally collapsed objects or black holes. Detailed predictions are presented. Discriminating features between neutron stars and black holes are also given. Subject headings:X-ray holes-neutron stars-binaries
