Ua hōʻike ka European Southern Observatory (ESO) i ka ʻike ʻana i kahi hanana nona ke koʻikoʻi ʻepekema he paʻakikī ke hoʻonui i kona koʻikoʻi. No ka manawa mua, ua ʻike ʻia ke kūkulu ʻia ʻana o kahi mea kaumaha i loko o kahi ulia hōkū neutron.
Ua ʻike ʻia ʻo nā kaʻina hana e hoʻokumu ʻia ai nā mea e hana nui ʻia ma nā ʻōpū o nā hōkū maʻamau, i nā pahū supernova, a i ʻole ma nā pūpū o waho o nā hōkū kahiko. Eia nō naʻe, a hiki i kēia manawa, ʻaʻole maopopo pehea e hana ʻia ai ke kaʻina hana hopu neutron wikiwiki, ka mea e hana ana i nā mea kaumaha loa ma ka papa periodic. Ua hoʻopiha ʻia kēia hakahaka i kēia manawa.
Wahi a ESO, i ka makahiki 2017, ma hope o ka ʻike ʻana i nā nalu umekaumaha e hōʻea ana i ka Honua, ua kuhikuhi ka hale kiaʻi i kāna mau telescope ma Chile i ko lākou kumu: kahi o ka hui ʻana o kahi hōkū neutron, ʻo GW170817. I kēia manawa, mahalo i ka mea kani X-shooter ma ka Very Large Telescope (VLT) a ESO, ua hiki ke hoʻokumu ʻia ua hoʻokumu ʻia nā mea kaumaha i ia mau hanana.
"Ma hope o ka hanana GW170817, ua hoʻomaka ka ʻauwaʻa telescope o ESO e nānā i ka pahū ʻana o ka kilonova ma nā ʻano nalu like ʻole. ʻO ke kikoʻī, ua loaʻa i ka spectrograph X-shooter kahi moʻo o nā spectra kilonova mai ka ultraviolet a kokoke i ka infrared. Ua hōʻike ka loiloi mua o kēia mau spectra i ke alo o nā laina element kaumaha, akā i kēia manawa wale nō i hiki i nā astronomers ke ʻike i nā element pākahi," wahi a ka puke pai ESO.
Ua ʻike ʻia ua hoʻokumu ʻia ka strontium ma muli o ke kuʻi ʻana o nā hōkū neutron, a pēlā e hoʻopiha ai i ka "loulou nalowale" i loko o ka mea pohihihi o ka hoʻokumu ʻia ʻana o nā mea kemika.
