Iplanethi enkulu yafumanisa ukujikeleza kufutshane neenkwenkwezi
Oku kufumanisa kunokubangela ukuba izazi ngeenkwenkwezi ziphinde ziphonononge ukwenziwa kweeplanethi.
Izazi ngeenkwenkwezi ziye zafumanisa ukuba iplanethi iyafana neJupiter ejikelezayo kufutshane encinci Inkwenkwezi ebomvu. Ezi nkwenkwezi zincinci zibomvu zezona zixhaphakileyo kwindalo iphela, kuba zimele ngaphezulu kwe-70% yeenkwenkwezi kwindalo yethu. Inkqubo ye- iinkwenkwezi ezibomvu zibonakaliswa ngokuba yingqele kwaye incinci; zikwahambelana nesihlanu senkqubo yethu yelanga, zinkulu njengelanga, kodwa ziphindwe ka-50 mnyama. Nangona kukho iinkwenkwezi ezibomvu ngamanani amakhulu, kuqikelelwa ukuba yi-10% kuphela yee-exoplanets eziza kujikeleza ezi nkwenkwezi.
Ngexesha lenkqubo yophando, izazi ngeenkwenkwezi bezihlalutya inkwenkwezi ebomvu ebomvu ekufuphi GJ 3512. Bafumanise ukuba le nkwenkwezi, emalunga neminyaka engama-31 yokukhanya ukusuka kwiplanethi yethu kunye nobukhulu bayo buphinda kasi-XNUMX kunelanga kwaye nangona bunokukhanya okukhulu, ayifani nelanga kangako.
Este iplanethikubizwa GJ 3512b Kuvela isigebenga segesi esabhaqwa ngokungalindelekanga ngexesha lophando olwenziwa ngababukeli beenkwenkwezi beCalar Alto, iMontsec kunye neSierra Nevada eSpain kunye neLas Cumbres Observatory eCalifornia.
I-GJ 3512b ibonakalise ukuba inkulu kakhulu kunokuba ibichaziwe kukufunyanwa kokuqala. Inkwenkwezi GJ 3512 ingama-250 kuphela amaxesha amakhulu kuneplanethi ye-GJ 3512b.
Okungakumbi okufumanekayo kunye neengcinga
Oososayensi bacebise ukuba kunokwenzeka ukuba enye iplanethi enobukhulu obukhulu ibikhe yajikeleza inkwenkwezi GJ 3512b; kuba ukujikeleza okukude kwenkwenkwezi kunye neplanethi enkulu efunyenweyo kubonisa ukuba le planethi ngexesha elithile ikho, ngokungenamandla bangena kumlo wokulwa kunye nenye iplanethi enkulu eyakhutshwa kwinkqubo yeenkwenkwezi.
Okwangoku, abaphandi bayaqhubeka nokubeka iliso kunye nokufunda le planethi ifunyenweyo kwaye baceba ukuqhubeka nokuhlalutya malunga neenkwenkwezi ezibomvu ezingama-300 ukuze baqhubeke nokufumana ii-exoplanets.
