Muchidimbu: Muna 2001, kuongororwa kweX-ray wavelengths neChandra X-ray Observatory kwakaratidza kuvapo kwegasi rinopisa kwazvo mukati meNGC 6543 ine tembiricha ye1.7 × 106 K. Zvinofungidzirwa kuti gasi rinopisa kwazvo rinokonzerwa nekudyidzana kwechisimba kwemhepo inokurumidza nyeredzi nezvinhu zvakamboburitswa. Kudyidzana uku kwakaburitsa bhuru remukati re nebula. Chandra kuongororwa kwakaratidzawo poindi sosi munzvimbo yenyeredzi yepakati. Chinyorwa cheiyi sosi chinotambanuka kuenda kuchikamu chakaoma cheX-ray spectrum, kusvika 0.51.0 <unk> keV. Nyeredzi ine tembiricha yemwenje inenge 100000 K ingangodaro isingatarisirwe kuburitsa zvine simba muX-ray, uye saka kuvapo kwavo chinhu chakavanzika. Zvinogona kuratidza kuvepo kweyakaipisisa tembiricha accretion mukati meiyo solar disk.
kudyidzana kwechisimba kwemhepo ine simba yenyeredzi nezvinhu zvakatobviswa kare
