Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 2001, kuongorora kwakaitwa paX-ray wavelengths neChandra X-ray Observatory kwakaratidza kuvapo kwegasi rinopisa zvikuru mukati meNGC 6543 rine tembiricha ye1.7×106 K. Zvinofungidzirwa kuti gasi rinopisa kwazvo rinobva mukubatana kwechisimba kwemhepo inokurumidza yenyeredzi nezvinhu zvakambobviswa. Kutapurirana uku kwakapaza bubble romukati renyeredzi. Kuongorora kwakaitwa neChandra kwakaratidzawo kuti pane nzvimbo inobva nyeredzi iri pakati. Ruzhinji rwenzvimbo iyi rwunotambanukira kuchikamu chakaoma chechiedza cheX-ray, kusvika ku0.5<unk>1.0 keV. Nyeredzi ine tembiricha yephotosphere inenge 100000 K haingatarisirwi kuti inoburitsa zvikuru mumwaranzi yeX-ray yakaoma, naizvozvo kuvapo kwayo chinhu chisingazivikanwi. Inogona kuratidza kuvapo kwedhisiki rinopisa zvikuru riri mukati merimwe gadziriro yenyeredzi mbiri. Iyo yakaoma X-ray data inoramba ichinakidza makore anopfuura gumi gare gare: Ziso reKatsi rakabatanidzwa mu2012 Chandra kuongorora kwe21 nyeredzi dzepakati dzeplanetary nebulae (CSPNe) munharaunda yezuva, iyo yakawana kuti: "Zvese kunze kweimwe yeiyo X-ray poindi masosi akaonekwa paCSPNe inoratidza X-ray spectra yakaoma kupfuura zvinotarisirwa kubva kune inopisa (~ 100000 K) nyeredzi yepakati photospheres, zvichida zvichiratidza huwandu hwepamusoro hwevatambi vaviri kuCSPNe. Dzimwe tsananguro dzinobvira dzinosanganisira mhepo dzinozvirova-rova kana kuti PN mass fallback".  Mubvunzo: Chii chakaziviswa neChandra X Ray Observatory?
kudyidzana kwechisimba kwemhepo ine simba yenyeredzi nezvinhu zvakatobviswa kare
