SPHEREx yana karanta yanayin duniyoyin da ke tsakanin taurari da taurarin yawo

Na'urar SPHEREx ta NASA tana gano bambancin sinadarai tsakanin brown dwarfs, abubuwan da suke samuwa kamar taurari amma ba su iya ci gaba da hada hydrogen kamar taurari na al'ada. Rahoton ranar 8 ga Oktoba ya bayyana binciken misalai 37 na kusa masu zafin jiki daban-daban.

Na'urar tana auna karfin haske a bangarorin tsawon igiya da yawa, ta samar da spectrum na kowane abu. Kwayoyin sinadarai suna shan wasu bangarorin hasken. Masana suna amfani da tsarin domin gano abubuwan yanayin iskar, ba daukar launin hoto a matsayin cikakken binciken sinadarai ba.

Binciken ya gano alamomin ruwa, carbon dioxide, carbon monoxide da methane. Samun wadannan kwayoyi ba ya tabbatar da tekuna, rayuwa ko kasa mai tauri. Ma'aunan suna bayyana kimiyyar abubuwa masu gas da dumi, da yadda yanayinsu yake bambanta daga wannan zuwa wancan.

Zafin jiki yana taimakawa wajen kwatantawa, amma ba ya bayyana komai. Wasu brown dwarfs masu zafi iri daya suna da spectra daban. NASA ta ce tsarin lissafi yana nuna manyan sauye-sauyen sinadarai, amma yana wahala wajen bayyana rikitarwar canjin girgije a wadannan abubuwa.

SPHEREx yana ganin tsawon igiyar haske da yanayin iskar Duniya yake hana nazarinsu sosai daga kasa. Bincikensa mai fadi zai ba da karin misalai. Duk da haka, binciken da aka wallafa ya shafi 37 ne. Dubban da ake nazari ba duk sakamakonsu aka kammala ba.

Aikin gaba shi ne gwada tsarin yanayi da karin ma'aunai da bayyana bambancin abubuwan. Brown dwarfs suna ba da hanyar binciken girgije da sinadarai a wajen tsarin Rana. Suna kuma nuna cewa lamba daya ta zafin jiki ba za ta iya bayyana dukkan abin da yake faruwa a wata duniya ba.
