Kormeerayaasha Koonfurta Yurub (ESO) ayaa ka warbixinaya diiwaangelinta dhacdo taas oo muhiimaddeeda marka laga eego dhinaca sayniska aan la qiyaasi karin. Markii ugu horeysay, sameynta curiye culus inta lagu jiro isku dhaca xiddigaha neutron ayaa la duubay.
Waxaa la og yahay in hababka inta lagu guda jiro ay curiyeyaasha ay ka dhacaan inta badan gudaha gudaha xiddigaha caadiga ah, qaraxyada supernova ama qolofka sare ee xiddigihii hore. Si kastaba ha ahaatee, ilaa hadda ma cadda sida ay u dhacdo waxa loogu yeero qabashada neutron-yada degdega ah, kaas oo soo saara walxaha ugu culus ee miiska xilliyeedka. Hadda farqigaas waa la buuxiyay.
Sida laga soo xigtay ESO, 2017, ka dib markii la ogaaday mowjadaha cufisjiidadka ee soo gaaraya Dhulka, kormeeraha ayaa hagay telescopes-yadeeda oo lagu rakibay Chile ilaha ay ka soo jeedaan: goobta isku dhafka xiddigaha neutron GW170817. Hadda, iyada oo ay mahad naqayso hebelaha X-shooter-ka ee ESO's Very Large Telescope (VLT), waxa suurtagashay in la ogaado in curiyeyaasha culus ay abuurmaan dhacdooyinkan oo kale.
"Kadib dhacdadii GW170817, kooxda ESO ee telescopes waxay bilaabeen inay la socdaan ololka kilonova ee soo koraya iyagoo eegaya mawjadaha dhaadheer ee kala duwan. Gaar ahaan, taxane kilonova spectra oo ka soo jeeda ultraviolet ilaa gobolka u dhow ee infrared ayaa la helay iyadoo la adeegsanayo spectrograph X-shooter. Durba falanqaynta bilawga ah ee muuqaaladan waxay soo jeedisay jiritaanka khadadka walxaha culculus ee ku jira, laakiin hadda oo kaliya cirbixiyayaashu waxay awoodeen inay aqoonsadaan walxaha shakhsi ahaaneed, "daabacaadda ESO ayaa tiri.
Waxaa soo baxday in strontium uu sameeyay natiijada isku dhaca xiddigaha neutron-ka. Sidaa darteed, "xiriirka maqan" ee halxiraalaha samaynta walxaha kiimikaad ayaa la buuxiyay.
