Einstein IPC imaging and spectral observations of the supernova remnant HB 9
Description
In radio wavelengths, HB 9 is a large supernova remnant. The central area of HB 9 has been observed with fairly complete coverage by four Einstein IPC fields. A soft X-ray image and results from analysis of X-ray spectra from the IPC observations are presented. HB 9 has spatial variations in X-ray temperature from 0.4 to 1.2 keV, with the temperature decreasing from center to edge. For a distance of 1.1 kpc, the 0.2-4 keV luminosity is 5 x 10 to the 34th ergs/s. A Sedov supernova remnant model does not fit HB 9's properties. Supernova remnant models for expansion into a three-component ISM give a satisfactory fit and yield an age of 14,000 yr. 19 references
