Theoretical Derivation of Σ-D Relation of Galactic SNRs
نویسندگان
چکیده
We derive the Σ-D relation of Galactic supernova remnants of shell-type separately at adiabatic-phase and at radiative-phase through two sets of different formulas, considering the different physical processes of shell-type remnants at both stages. Also statistics on Galactic shell-type remnants about 57 was made. Then we do some comparison with other results obtained before. It shows that all the best fit lines in the Σ-D relation plots newly are to some extent flatter than those derived by some authors at early time. Our theoretical and statistical outcomes are in somewhat good consistency. Subject headings: methods: — statistical — analysis — (ISM:) supernova remnants

The Radio Surface Brightness to Diameter Relation for Galactic Supernova Remnants: Sample Selection and Robust Analysis with Various Fitting Offsets
In this paper we present new empirical radio surface brightness-to-diameter (Σ−D) relations for supernova remnants (SNRs) in our Galaxy. We also present new theoretical derivations of the Σ − D relation based on equipartition or on constant ratio between cosmic rays and magnetic field energy. A new calibration sample of 60 Galactic SNRs with independently determined distances is created. Instea...

The selection effects applicable to the identification of Galactic supernova remnants (SNRs) at radio wavelengths are discussed. Low surface brightness remnants are missing, as are those with small angular sizes (including young but distant SNRs). Several statistical properties of Galactic SNRs are discussed, including the surface-brightness/diameter (Σ−D) relation. The wide range of intrinsic ...

Technological advances in radio telescopes and X-ray instruments over the last 20 years have greatly increased the number of known supernova remnants (SNRs) and led to a better determination of their properties. In particular, more SNRs now have reasonably determined distances. However, many of these distances were determined kinematically using old rotation curves (based on R⊙ = 10 kpc and V⊙ ...
متن کاملConstraints on the distribution of supernova remnants with Galactocentric radius
Supernova remnants (SNRs) in the Galaxy are an important source of energy injection into the interstellar medium, and also of cosmic rays. Currently there are 294 known SNRs in the Galaxy, and their distribution with Galactocentric radius is of interest for various studies. Here I discuss some of the statistics of Galactic SNRs, including the observational selection effects that apply, and diff...
