Lecture1. Structure of Neutron Stars

Lecture1. Structure of Neutron Stars. Sergei Popov (SAI MSU). Artistic view. For NSs we can take T=0 and neglect the third equation. Hydrostatic equilibrium for a star. For a NS effects of GR are also important. M/R ~ 0.15 (M/M ? ) (R/10 km ) -1 J/M ~ 0.25 (1 ms/P) (M/M ? )(R/10km) 2.
