Namuhla, ikakhulukazi ngenxa yobuchwepheshe obusha obuqala ukuba amathuluzi wangempela ababhula ngezinkanyezi nezinkanyezi emhlabeni wonke, kutholwa inqwaba yamaplanethi, ngalinye linobuciko balo obenza bahluke futhi bathakazelise futhi badinga inani elikhulu lamahora okutadisha.
Ngokuqondile nangenxa yomsebenzi omkhulu odinga ukuqonda zonke izici ezingalethwa yilawa maplanethi, iningi labo liyatholakala, liyabhabhadiswa futhi, ngaphandle kwalapho likhanga ngenxa yesizathu esithile, imvamisa ziyakhohlakala kuze kube yilapho iqembu elithile selibe nesikhathi esanele sokuqala isifundo ngezici zalo.
I-KELT-9b, igesi enkulu enezinhlayiya zensimbi nezensimbi emoyeni wayo
Kulo msebenzi onzima namuhla kufanele sikhulume ngeposi eyaziwa ngokuthi UKELT-9b, ngokufanayo usanda kungena ohlwini lwama-exoplanets athakazelisa kakhulu atholakele kuze kube manje futhi hhayi impela ngoba kungahlalwa kuzo, kunalokho, kepha ngoba kushisa kakhulu okutholakale kuze kube manje izazi zezinkanyezi, izinga lokushisa okuthi, njengoba isihloko salokhu kungena, liphakeme kakhulu kunalokho ongakucabanga.
Ukungena emininingwaneni ethe xaxa, i-KELT-9b ivelele ngokoqobo ngokuba nokushisa okuphezulu kangangoba kungokokuqala ukuthi izazi zezinkanyezi zibone ama-athomu wamahhala wensimbi ne-titanium emkhathini wawo. Ukukusiza uzibeke ungconywana, sikhuluma ngakho iplanethi okushisa kwayo kuzoba ngaphezu kwama-4.300 degrees Celsius, into ehlaba umxhwele, ikakhulukazi uma sicabanga ukuthi iLanga lethu linezinga lokushisa langaphakathi elingama-6.000 degrees Celsius.
IKELT-9b izungeza inkanyezi KELT-9, etholakala eminyakeni engu-620 yokukhanya ukusuka eMhlabeni
Ngenxa yokushisa okuphezulu ngokweqile, njengoba bekulindelekile, sikhuluma ngeqiniso lokuthi i-KELT-9b ayilutho nje kuphela kolunye lwezinto ezibizwa ngokuthi yi-giants gas nokuthi iqiniso lokushisa kweplanethi selibe yindaba yokufunda kufanele ngokunembile kufayela le- ubuhlobo onabo nenkanyezi yakho.
Ngalo mqondo kufanele siveze ukuthi i-KELT-9b izungeza i- inkanyezi HD 195686, eyaziwa kakhulu njenge-KELT-9. Le nkanyezi isendaweni ecishe ibe yiminyaka eyi-620 yokukhanya ukusuka kwiplanethi yethu futhi iliphinda kabili ubukhulu beLanga lethu. Ngokuqondene neKELT-9b, le planethi, yize izazi zezinkanyezi zingakwazanga ukukala ngokunemba okukhulu ibanga elihlukane nalo inkanyezi yakhe, uma bekwazi lokho gcwalisa ithanga elizungeze lona ngamahora angama-36 kuphela okusho ukuthi kumele usondele kakhulu kuyo.
I-KELT-9b itholakele ngenxa yokusetshenziswa kwe I-HARPS-N, ithuluzi elise-Canary Islands
Ukubaluleka kokuthola iplanethi enjengale kuxhomeke emibonweni ebesinayo kuze kube manje mayelana nokuthi kungenzeka yini ukuthi inkanyezi efana neJupier yethu ishise ngokwanele ukuba ingaqukatha iminonjana yezinsimbi zamahhala emkhathini wayo. Ngemuva kwaso sonke lesi sikhathi sokulinda, ekugcineni sikwazile ukuthola endaweni yokuqala futhi singakubuka futhi sikutadishe ngqo.
Njengoba kulindelekile, asikwazi ukubheka into enjengalesi sikhulu segesi, ikakhulukazi maqondana nokuhlala, yize iqiniso, njengoba izazi zezinkanyezi eziningi sezivele ziphawule, isifundo salo singaba usizo olukhulu ekusizeni ukucubungula kahle amathuluzi wokulinganisa abale inani lezakhi zamakhemikhali emkhathini we-exoplanet Futhi lokhu kuyadingeka ukunquma ukuthi inkanyezi ethile esihlangana nayo ngokuzayo iyakwazi ukuhlala noma cha.
Okokugcina, ngithanda ukukutshela, ikakhulukazi ngesikhathi lapho sibona ukuthi ohulumeni abathile nezikhungo zocwaningo nezentuthuko basebenzisa kanjani imali eningi kakhulu kumaphrojekthi lapho befuna ukuqhubeka nokwenza ngcono amathuluzi asivumela ukuthi senze lolu hlobo lokutholwa, okuyinto i-KELT-9b eyenziwe ngenxa yokusetshenziswa kwe-High Precision Radial Velocity Planet Finder eNyakatho Nenkabazwe o I-HARPS-N, Ithuluzi okungelilutho ngaphezu kwesibaluli esibonisa ngokunemba okuphezulu esise- Iziqhingi zaseCanary.
