Iplanethi enkulu yathola ukuzungeza eduze kwenkanyezi encane
Lokhu kutholakala kungadala ukuthi izazi zezinkanyezi ziphinde zihlolisise ukwakheka kwamaplanethi.
Izazi zezinkanyezi zithole i- iplanethi kufana neJupiter ezungeza eduze kokuncane Inkanyezi Ebomvu. Lezi zinkanyezi ezincane ezibomvu ziphakathi kwezinto ezivame kakhulu endaweni yonke, ngoba zimele ngaphezulu kwezingu-70% zezinkanyezi endaweni yethu yonke. I- izinkanyezi ezibomvu zikhonjiswa ngokubanda nokuncane; nazo zihambisana nengxenye yesihlanu yesimiso sethu sonozungezilanga, zinkulu njengelanga, kodwa zimnyama ngokuphindwe ka-50. Yize kunezinkanyezi ezibomvu ngamanani amakhulu, kulinganiselwa ukuthi yi-10% kuphela yama-exoplanet afinyelela kulezi zinkanyezi.
Ngesikhathi kwenziwa ucwaningo, izazi zezinkanyezi zazihlaziya inkanyezi eseduze ebomvu ebomvu ebizwa I-GJ 3512. Bathola ukuthi le nkanyezi, etholakala eminyakeni ecishe ibe ngama-31 yokukhanya kusuka kuplanethi yethu nobukhulu bayo incane ngokuphindwe kasishiyagalombili kunelanga futhi yize inokukhanya okukhulu, ayifani nelanga kangako.
Este iplanethiubizile GJ 3512b Kuvele kube yisidlakela segesi esatholakala ngokungalindelekile ngesikhathi kuphenywa okwenziwa yizikhungo zezinkanyezi zaseCalar Alto, Montsec naseSierra Nevada eSpain kanye neLas Cumbres Observatory eCalifornia.
I-GJ 3512b kuvele ukuthi ibinkulu kakhulu kunalokho obekunqunywa ekutholakaleni kokuqala. Inkanyezi i-GJ 3512 inkulu kuphela izikhathi ezingama-250 kuneplanethi engu-GJ 3512b.
Ukutholwa okuningi kanye nemibono
Ososayensi baphakamise ukuthi kungenzeka ukuthi kungenzeka ukuthi kunenye futhi iplanethi enkulukazi engake yazungeza inkanyezi i-GJ 3512b; ngoba ukujikeleza kwenkanyezi okukude neplanethi enkulu etholakele kukhombisa ukuthi leplanethi ngesikhathi esithile lapho ikhona, yangena ekudonseni kwempi edonsela phansi nenye iplanethi enkulu kamuva ekhishwa ohlelweni lwenkanyezi.
Okwamanje, abacwaningi bayaqhubeka nokuqapha nokutadisha le planethi etholakele futhi bahlela ukuqhubeka nokuhlaziya izinkanyezi ezibomvu ezingama-300 ngaphezulu ukuze baqhubeke nokuthola ama-exoplanet.
Ososayensi banelungelo lobunikazi lokwenziwa kohlelo lokuqoqa imfucumfucu yasemkhathini
