I-European Southern Observatory (ESO) ibika ukutholakala kwesenzakalo okunzima ukusigcizelela ukubaluleka kwaso ngokwesayensi. Okokuqala ngqa, kutholakale ukwakheka kwento esindayo ekushayisaneni kwezinkanyezi ze-neutron.
Kuyaziwa ukuthi izinqubo ezakhiwa ngazo izakhi zenzeka ikakhulukazi ezingxenyeni zezinkanyezi ezivamile, ekuqhumeni kwe-supernova, noma emagobolondweni angaphandle ezinkanyezi ezindala. Kodwa-ke, kuze kube manje, akucaci ukuthi inqubo ebizwa ngokuthi i-fast neutron capture, eyakha izakhi ezisindayo kakhulu kuthebula le-periodic, yenzeka kanjani. Lesi sikhala sesigcwalisiwe manje.
Ngokusho kwe-ESO, ngo-2017, ngemva kokubona amagagasi adonsela phansi afinyelela eMhlabeni, indawo yokuhlola yaqondisa amateleskopu ayo eChile emthonjeni wawo: indawo lapho kwahlangana khona izinkanyezi ze-neutron, i-GW170817. Manje, ngenxa yethuluzi le-X-shooter eliku-Very Large Telescope (VLT) ye-ESO, kuye kwenzeka ukuthi kutholakale ukuthi izakhi ezisindayo zakhiwa ezenzakalweni ezinjalo.
"Ngemuva kwesehlakalo se-GW170817, inqwaba yama-telescope e-ESO yaqala ukuqapha ukuqhuma kwe-kilonova okuthuthukayo ebangeni elibanzi lama-wavelength. Ngokukhethekile, i-X-shooter spectrograph ithole uchungechunge lwama-kilonova spectra kusukela ku-ultraviolet kuya ku-near-infrared. Ukuhlaziywa kokuqala kwala ma-spectra kusikisele ukuba khona kwemigqa ye-element esindayo, kodwa manje kuphela lapho izazi zezinkanyezi sezikwazile khona ukuhlonza izakhi ngazinye," kusho incwadi ye-ESO.
Kwatholakala ukuthi i-strontium yakhiwa ngenxa yokushayisana kwezinkanyezi ze-neutron, ngaleyo ndlela kwagcwaliswa "isixhumanisi esingekho" emfihlakalweni yokwakheka kwezakhi zamakhemikhali.
