| Abstract: | High resolution (3 arcsec-4 arcsec) maps of three compact sources in CTB 80, observed with the Very Large Array at 6 and 20
cm wavelengths are presented. The central core consists of a limb-brightened shell (of diameter 30 arcsec) superimposed on
a diffuse emission of size 75 arcsec x 45 arcsec. The compact sources 1949 + 324 and 1952 + 332 located near the tips of the
southwest and northeast ridges are rather remarkable and possibilities for these to be fragments ejected by the SN are examined.
1949 + 324 is fully resolved by the 4 arcsec beam and shows structure with multiple components oriented perpendicular to the
ridge. 1950 + 326 is a background radio source. |
