Abstract

We present new population synthesis calculations of close young neutron stars. In comparison with our previous investigation we use a different neutron star mass spectrum and different initial spatial and velocity distributions. The results confirm that most of ROSAT dim radioquiet isolated neutron stars had their origin in the Gould Belt. Several tens of young neutron stars can be identified in future in ROSAT data at low galactic latitudes and some of them also can be EGRET unidentified sources.
