Isolated neutron stars: evolution and LogN/LogS


We model populations of isolated neutron stars in the Galaxy following their orbital and magneto-rotational evolution. It is shown that accretors become more abundant than coolers at fluxes below approximately 10-13 erg cm-2 s-1, and one can predict that about one accreting neutron star per square degree should be observed at the Chandra and Newton flux limits of approx. 10-16 erg cm-2 s-1. The weak ROSAT sources, tentatively associated with isolated neutron stars, can be relatively young, cooling objects, if the neutron star birth rate in the solar vicinity during the last approx. 106 yr was higher than inferred from radiopulsar observations.
