Statistics of Galactic Supernova Remnants (continued)
Jian-Wen Xu ; Fang-Jun Lu ;
Date 2 Sep 2009
AbstractOur statistics on Galactic supernova remnants (SNRs) shows that the electrons temperature ($T$) of hard X-ray and the shock waves traveling velocity ($upsilon$) decreases with ages ($t$) for all-sort remnants. However, the shock waves swept-up mass ($M_{su}$) of ISM increases with the age. Second, the remnant radio fluxes ($S$) at 1 GHz increase slightly with ISM electrons density ($n_0$). At last, the number distributions illustrate that the supernovae (SNe) initial kinetic energy ($E_0$), hydrogen column density ($N_H$), electrons temperature (kT) of hard X-ray, magnetic field ($B$) and the shock waves swept-up mass ($M_{su}$) of ISM mainly peaked at $(1 sim 10) imes 10^{50}$ ergs, $(1 sim 10) imes 10^{21}$ cm$^{-2}$, a few KeV, 100 $mu$G and 10$sim$100 $M_{odot}$, respectively.
