I-European Southern Observatory (ESO) ibika ukubhaliswa komcimbi ukubaluleka kwawo ngokombono wesayensi okungenakulinganiswa ngokweqile. Ngokokuqala ngqa, ukwakheka kwesici esindayo ngesikhathi sokungqubuzana kwezinkanyezi ze-neutron kurekhodiwe.
Kuyaziwa ukuthi izinqubo lapho kwakheka izakhi zenzeka ikakhulukazi ngaphakathi kwezinkanyezi ezijwayelekile, ekuqhumeni kwe-supernova noma kumagobolondo angaphandle ezinkanyezi ezindala. Kodwa-ke, kuze kube manje bekungakacaci ukuthi kwenzeka kanjani lokho okubizwa ngokuthi ukuthunjwa kwama-neutron asheshayo, okukhiqiza izakhi ezisinda kakhulu zethebula le-periodic. Manje lesi sikhala sesivaliwe.
Ngokusho kwe-ESO, ngo-2017, ngemva kokuthola amagagasi adonsela phansi efika eMhlabeni, i-observatory yaqondisa izibonakude zayo ezifakwe eChile emthonjeni wazo: indawo yokuhlanganisa inkanyezi ye-neutron GW170817. Futhi manje, sibonga isamukeli se-X-shooter ku-ESO's Very Large Telescope (VLT), kube nokwenzeka ukuthola ukuthi izinto ezisindayo ziyakhiwa phakathi nemicimbi enjalo.
βKulandela umcimbi i-GW170817, uxhaxha lwezibonakude ze-ESO zaqala ukuqapha ukuvutha kwe-kilonova ekhulayo phezu kobubanzi obuhlukahlukene bamaza. Ikakhulukazi, uchungechunge lwe-kilonova spectra olusuka ku-ultraviolet ukuya endaweni eseduze ne-infrared lutholwe kusetshenziswa i-X-shooter spectrograph. Kakade ukuhlaziywa kokuqala kwalezi zibukeli kuphakamise ukuba khona kwemigqa yezinto ezinzima kuzo, kodwa manje kuphela izazi zezinkanyezi ezikwazile ukuhlonza izakhi ngazinye,β kusho incwadi ye-ESO.
Kwavela ukuthi i-strontium yakhiwa ngenxa yokushayisana kwezinkanyezi ze-neutron. Ngakho, "isixhumanisi esingekho" emfumbeni wokwakheka kwezakhi zamakhemikhali sigcwaliswa.
