Statistics of Galactic Supernova Remnants (continued) | Jian-Wen Xu

2 Sep 2009 | Abstract: | Our 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. | Source: | arXiv, 0909.0432 | Services: | Forum | Review | PDF | Favorites |
