Region 1 has a density below 5 × 10 11 g cm 3 , region 2 has a density from 5 × 10 11 to 10 15 g cm 3 and region 3 has a density > 10 15 g cm 3 . In region 1, the pressure is generated by an electron gas obeying the laws of atomic physics and the semi-empirical ...
The neutron star of the pulsar HER X-1 does not precess with a 35-day period Calculations performed on Exosat data reveal that the neutron star of Her X-1 does not precess with a 35-day period. It is concluded that a different mechanism must be behind the Her X-1 35-day activity ...

Globular clusters (GCs) are the ideal environment for the formation of neutron stars (NSs) and millisecond pulsars (MSPs). NSs origin and evolution provide a useful information on stellar dynamics and evolution in star clusters. NSs are among the most interesting astrophysical objects, being precurs...
