| Abstract: | It has been shown that the mass of neutron stars obtained from equations of state based on nuclear theory depend upon the number of baryons assembled in it but not on the type of interactions considered. On examining the behaviour of different equations of state based on nuclear theories, a simple polytropic equation of state,P = (K/N)(p –p
s)N is proposed. The results obtained forN=1.75 cover the entire range of neutron star masses obtained from the equations of state based on nuclear theories and give a maximum mass of 2.8M
 . Depending upon various mechanisms for energy output the mass of Crab pulsar is estimated to range from 0.32M
to 1.5M
. The relation connecting the coordinate mass,M, and the rest mass,M
0, may be written asM/M
 0.93 (M
0/M)0.9. |
