Namhlanje, ngakumbi ngenxa yetekhnoloji entsha eqala ukubakho izixhobo zokwenene zabavumisi ngeenkwenkwezi kunye neenkwenkwezi kwihlabathi liphela, inani elikhulu leeplanethi ziyafunyanwa, nganye inezinto zayo ezizodwa ezenza ukuba zahluke kwaye zinomdla kwaye zifuna inani elikhulu leeyure zokufunda.
Ngokuchanekileyo nangenxa yomsebenzi omkhulu ofuna ukuqonda zonke izinto ezizezinye ezinokuthi ziboniswe zezi zijikelezi-langa, uninzi lwazo luyafunyanwa, lubhaptiziwe kwaye, ngaphandle kokuba lutsala umdla ngesizathu esithile, zihlala zilityelwe de iqela libe nexesha elaneleyo lokuqalisa isifundo kwiimpawu zazo.
I-KELT-9b, isigebenga segesi esineentsimbi kunye neentsimbi zentsimbi kumoya waso
Kulo msebenzi onzima, namhlanje kufuneka sithethe malunga neposi eyaziwa njenge I-KELT-9b, enye ne ndingene nje kuluhlu lwezona zinto zithandwayo exoplanets ezifunyenwe ukuza kuthi ga ngoku hayi ngokuchanekileyo kuba ingahlalwa, ngokuchaseneyo, kodwa kuba sesona shushu sithe safunyanwa ukuza kuthi ga ngoku zizazi ngeenkwenkwezi, iqondo lobushushu, njengoko isihloko salo ngeniso lisithi, liphezulu kakhulu kunokuba unokucinga.
Ukuya kwinkcukacha ezithe kratya, i-KELT-9b ngokoqobo imele ukuba nobushushu obuphezulu kangangokuba lixesha lokuqala ukuba izazi ngeenkwenkwezi ziqwalasele iiathom zasimahla zentsimbi kunye neetitanium kumoya wayo. Ukukunceda ukuba uzibeke ngcono, sithetha ngazo Iplanethi enamaqondo obushushu angaphezulu kwe-4.300 degrees Celsius, into ebabazekayo, ngakumbi xa sicinga ukuba iLanga lethu linobushushu bangaphakathi bama-6.000 degrees Celsius.
I-KELT-9b ijikeleza inkwenkwezi KELT-9, ebekwe kwiminyaka engama-620 yokukhanya ukusuka eMhlabeni
Ngenxa yobushushu obuphezulu kakhulu, njengoko bekulindelwe, sithetha ngento yokuba i-KELT-9b ayisiyonto ingaphezulu kwesinye sezinto ezibizwa ngokuba ziigesi ezinkulu kunye nenyani yokuba ubushushu bomhlaba buye baba yinto yokufunda ngokuchanekileyo ukuya ubudlelwane onabo nenkwenkwezi yakho.
Ngale ndlela kufuneka sityhile ukuba i-KELT-9b ijikeleza i inkwenkwezi HD 195686, eyaziwa njengeKELT-9. Le nkwenkwezi ibekwe malunga neminyaka engama-620 yokukhanya ukusuka kwiplanethi yethu kwaye ibuphinda kabini ubunzima beLanga lethu. Ngokubhekisele kwi-KELT-9b, le planethi, nangona izazi ngeenkwenkwezi zingakhange zikwazi ukulinganisa ngokuchanekileyo umgama owahlula kuwo inkwenkwezi yakhe, ukuba bayayazi loo nto Gcwalisa ithanga ukujikeleza ngeenxa zonke kwiiyure ezingama-36 Oko kuthetha ukuba kufuneka usondele kakhulu kuyo.
I-KELT-9b ifunyenwe inombulelo kusetyenziso lwe IHARPS-N, isixhobo esikwiiCanary Islands
Ukubaluleka kokufumanisa iplanethi enje kulele kwiingcinga zokuba kude kube ngoku sinethuba lokuba inkwenkwezi efana neJupier yethu yayishushu ngokwaneleyo ukuba ingaqulatha umkhondo wesinyithi simahla kwimozulu yayo. Emva kwalo lonke eli xesha lokulinda, ekugqibeleni sikwazile ukufumanisa kwisithuba sokuqala kwaye sinokubona kwaye sifunde ngokuthe ngqo.
Njengoko kulindelwe, asinakho ukujonga into eluncedo kule gesi inkulu, ngakumbi ngokubhekisele ekuhlaleni, nangona inyani, njengoko izazi ngeenkwenkwezi ezininzi sele zichazile, isifundo sayo sinokuba Uncedo olukhulu ekuncedeni ukucoca izixhobo zomlinganiso ezibalela umyinge wezinto zeekhemikhali kwiatmosfera yeatmosfera kwaye oku kuyimfuneko ukumisela ukuba inkwenkwezi ethile esihlangana nayo kwixesha elizayo iyakwazi ukuhlala okanye hayi.
Okokugqibela, ndingathanda ukukuxelela, ngakumbi ngexesha apho sibona ukuba oorhulumente abathile kunye nophando kunye namaziko ophuhliso achitha njani ukonyuka okukhulu kwemali kwiiprojekthi ezifuna ukuqhubeka nokuphucula izixhobo ezisivumela ukuba senze olu hlobo lokufumanisa, I-KELT-9b yenziwe ngombulelo kusetyenziso lwePlanethi ePhakamileyo ye-Precision Radel Velocity Finder kwiNtla yeNtlabathi o IHARPS-N, Isixhobo esingeyonto ingaphezulu kwesicatshulwa somgangatho ophezulu esikwi- IItary Islands.
