OBSERVATION OF COMPOSITE TYPE SNRS G116.5+11 & G117.4+5
ABSTRACT
We propose the observation of composite type SNR G116.5+1.1 and G117.4+5 . The morphology of these SNR's are shell type in radio and are center filled type in X-ray. This class of SNR's has been revealed to emitting thermal spectrum in X-ray. ASCA's observation shows these spacally resolved spectra are not uniform. We found the gradience of metal abundances in spece. We want to determin the origin of this class of SNR, evaporation or remaining ejecta, through getting the gradience of metal abundance of each heavy element from spacally resolved spectorum.
