X-Ray Emission from Mass Accreting Neutron StarsHercules X-1 - which is the best-known among all accreting neutron stars. In particular we shall discuss recent progress which has been made in understanding (1) the geometrical situation of the neutron star and its immediate surroundings and (2) the 35-day-cycle of the source.

Cosmic-Ray Acceleration in UHE and VHE Gamma-Ray Sources including Her X-1, LMC X-4, Cen X-3 and 4U 0115 + 63. These observations, if subsequently found to be statistically significant, imply the acceleration of high energy cosmic rays in these sources. In this paper, we discuss briefly some of the models so far proposed for cosmic ray acceleration in th

Source Mechanisms (Accretion Objects)e 10. eV). Dynamo action by an accretion disc (Brecher) seems confined to large distances from the neutron star in many cases, where little of the gravitational energy is tapped. Accreting matter probably has too low a density to sustain shock acceleration in a 10. gauss field. Some neutron stars sp
