I-11-Jupiter-mass exoplanet ebizwa ngokuba yi-HD 106906 b, eboniswe kulo mzekeliso wegcisa, ihlala kwindawo engenakulindeleka ejikeleze inkwenkwezi ephindwe kabini engama-336 yeminyaka yokukhanya.I-NASA, i-ESA, kunye noM. Kornmesser (i-ESA / iHubble) Abanye oososayensi kudala bekholelwa ukuba kungakho iplanethi yesithoba, okanye iPlanethi yesithoba, ejikeleza ilanga emaphethelweni e inkqubo yelanga (kwaye hayi, ayingoPluto). Ukuqwalaselwa ngokutsha kwe-exoplanet kwinkqubo yeenkwenkwezi ekude kunika imikhondo enokusinceda ukuba siqinisekise loo nto.
Ngokophando olupapashwe kwi Ijenali yeenkwenkwezi NgoLwesine IHubble Space Telescope Ufumene i-exoplanet enkulu, okanye iplanethi engaphandle kwenkqubo yelanga, ejikeleza inkqubo yeenkwenkwezi ezimbini ezingama-336 zeminyaka yokukhanya ukusuka kuthi enokufana kakhulu nePlanethi yesithoba-ukuba ikhona.
Iplanethi engaqondakaliyo, ebizwa ngokuba yi-HD106906b, iphindaphindwe kalishumi elinanye ubunzima beJupiter kwaye ijikeleza iinkwenkwezi zayo ezimbini ezivela kumgama oziikhilomitha ezingama-67 ezigidi, okanye amaxesha angama-730 umgama ukusuka eMhlabeni uye elangeni. Ukusuka kude kude, kuthatha i-exoplanet eyi-15,000 yeminyaka yoMhlaba ukugqiba umjikelo omnye ujikeleze iinkwenkwezi.
Oososayensi bayabazi ubukho be-HD106906b ukusukela ngo-2013 xa yafunyanwa yiMagellan Telescopes eLas Campanas Observatory eChile. Kodwa kungenxa yophando lwamva nje apho abaphandi babenakho ukufumanisa ukujikeleza kwayo, kuba iteleskopu yeHubble yanikezela ngemilinganiselo echanekileyo yokuhamba kweplanethi kwisithuba seminyaka eli-14.
Inkqubo yeenkwenkwezi ezimbini ineminyaka nje eyi-15 yezigidi ubudala, izazinzulu zithi, kwaye ijikelezwe yidiski enothuli lwentsalela eshiywe kukwenziwa kweenkwenkwezi eziphambili kunye neeplanethi ezijikelezayo. Izazi ngeenkwenkwezi ziye zafunda le nkqubo kangangeminyaka eli-15 ngenxa yokuba zicinga ukuba iiplanethi zinokudaleka kule diski.
Inkqubo yelanga inediski enothuli efanayo eyaziwa ngokuba yiKuiper Belt ngaphaya kwePluto. Izazi ngeenkwenkwezi ziye zabona imijikelo ethile engaqhelekanga yezinye izijikelezi-langa kunye neeplanethi ezinqabileyo ezivela kulo mmandla. Kwaye abanye bakholelwa ukuba isihloko kunye nokuhamba kwaso okungaqhelekanga kubangelwa yiplanethi efihliweyo ekufuphi ephantse ibe li-10 ubukhulu bomhlaba kwaye ihamba ecaleni kwe-eccentric orbit.
Ngaphandle kokungafumaneki kwePlanethi yethoba ukuza kuthi ga ngoku, ukujikeleza kweplanethi kungathathelwa ingqalelo ngokusekwe kwimpembelelo yayo kwizinto ezahlukeneyo zenkqubo yelanga engaphandle, uRobert De Rosa, umbhali-mbhali wesifundo kunye nesazi ngeenkwenkwezi kwi-European Southern Observatory eChile, kuchaziwe kwingxelo. Uqikelelo lwe-orbit yeplanethi yethoba iyafana nale nto siyibonayo nge-HD 106906b.
Abaphandi bathi i-HD106906b inokuba yazalwa ikufutshane neenkwenkwezi zayo kwaye yakhatywa yimikhosi yomxhuzulane weenkwenkwezi eziphindwe kabini. Kodwa ukuba enye inkwenkwezi idlulile, ngeyayigcina exoplanet kwinkqubo ngaphandle kokubhadula.
Inkqubo efanayo inokwenzeka ukuba yenzeke kwiPlanethi yesithoba, apho yenziwa kufutshane nezinye iiplanethi kwiminyaka yokuqala yenkqubo yelanga yaza yakhutshwa ngumxhuzulane omkhulu kaJupiter. Kwaye ke amandla omxhuzulane wenkwenkwezi edlulayo ayibuyisela umva kumjikelezo kwinkqubo yelanga. Sithe chu siqokelela ubungqina obufunekayo ukuze siqonde ukwahluka kweeplanethi ezongezelelweyo kunye nendlela ezinxulumana ngayo nezinto ezixakayo zenkqubo yethu yelanga, omnye umbhali-mbhali wokufunda uPaul Kalas, unjingalwazi odibeneyo wesayensi yeenkwenkwezi kwiYunivesithi yaseCalifornia, eBerkeley, utshilo. kwingxelo.
