Issue Date: | 2006 | Rank: | M34 | Publisher: | International Astronomical Union IAU | Related Publication(s): | Supernovae: One Millennium After SN1006, 26th meeting of the IAU, Joint Discussion 9 | Conference: | Meeting of IAU (26 ; 2009 ; Prague) | Abstract: | An analysis of the broadband radio spectrum (from 38 MHz to 3.9 GHz) of the Galactic supernova remnant (SNR) HB3 (G132.7+1.3) is presented. A single synchrotron component appears to be insufficient to adequately fit the radio spectrum of this source, because of the obvious spectrum curvature at the higher radio frequencies. The simulated spectrum using a combination of a synchrotron component and a thermal bremsstrahlung component is presented. We also discuss properties of this latter component and estimate the ambient density implied by the presence of this component to be n ~10-40 cm^-3. |
