Impilo ku-Super-Earths ingase ibe nesikhathi esengeziwe sokuthuthukisa kanye nokushintsha ngenxa yezindawo zayo kazibuthe eziqhubekayo ezivikela emisebeni ye-cosmic eyingozi, ngokusho kocwaningo olusha olushicilelwe kumagazini i-Science.
Umkhathi uyindawo eyingozi.Ukusakazwa kwezinhlayiya ezishajwayo ezisondelene kakhulu nejubane lokukhanya, ezikhishwa ezinkanyezini nasemithala ekude, amaplanethi amabhomu.Imisebe enamandla ihlukanisa umkhathi bese yenza ulwandle oluphezu kweplanethi yome ngokuhamba kwesikhathi, luwenze. iwugwadule futhi ayikwazi ukusekela ukuphila okuhlalwayo.Nokho, imisebe ye-cosmic ichezukiswa kude noMhlaba ngoba ivikelwe amandla ayo kazibuthe.
Manje, ithimba labacwaningi eliholwa yi-Lawrence Livermore National Laboratory (LLNL) likholelwa ukuthi i-super-Earths - amaplanethi amakhulu kakhulu kunoMhlaba kodwa angaphansi kwe-Neptune - angase abe nezizibuthe. Eqinisweni, kulinganiselwa ukuthi amabhamuza awo okuzivikela ahlala eqinile kunalezo ezizungeza uMhlaba, okusho ukuthi ukuphila ezindaweni zazo kungaba nesikhathi esengeziwe sokuthuthuka nempilo.
"Nakuba kunezidingo eziningi zeplanethi ekwazi ukuhlala kuyo, njengezinga lokushisa elingaphezulu elikwazi ukukhiqiza amanzi awuketshezi, ukuba ne-magnetosphere engakwazi ukumelana nemisebe yelanga isikhathi eside kunganikeza isikhathi eside ukuze ukuphila kuguquke," kusho uRichard. iphepha.Umbhali oholayo uKrause, isazi sefiziksi e-LLNL, utshele iThe Register.
Isihluthulelo sensimu kazibuthe ephikelelayo ukuba nenkango yensimbi ewuketshezi ephola kancane kancane.Indawo kazibuthe yomhlaba ikhiqizwa ungqimba lwensimbi encibilikisiwe ezungeza umnyombo wensimbi oqinile. amandla insimu kazibuthe.
Nokho, izinga lokushisa lensimbi encibilikisiwe eligqitshwe amakhilomitha angu-2,890 noma amamayela angu-1,800 ngaphansi kobuso boMhlaba liyabanda. Ekugcineni lizophola lize limiswe ngokuphelele.Kuleli qophelo, ijeneretha yayo yangaphakathi izoyeka ukujikeleza futhi ngeke isakwazi ukusekela amandla kazibuthe.I-Earth's amandla kazibuthe azonyamalala eminyakeni engaba yizigidi eziyizinkulungwane eziyi-6.2.
“Lapho i-ayoni iqina, ikhipha amandla nezinto ezilula zibe yi-ayoni enguketshezi, eyenza ijeneretha ibe namandla isikhathi eside.Ngesinye isikhathi, izinga lokushisa le-liquid core liyaphola lize lincibilike, okusho ukuthi lizoqala ukuba yiqhwa,” kuchaza u-Klaus. izinga lokushisa.
Ngamanye amazwi, i-super-Earth's core idinga ukupholisa izinga lokushisa eliphansi kakhulu ngaphambi kokuba iqine.Ama-cores awo amakhulu asho nokuthi akhipha ukushisa kancane kunoMhlaba.
“Sithole ukuthi i-super core izoqina ngo-30% ubude kunomongo… Ngenxa yemiphumela eqhudelanayo yamandla agciniwe kanye nendawo engaphezulu, izinongo zamaplanethi amancane kunoMhlaba azoqina ngokushesha, ngesilinganiso sesikhathi eside kakhulu sokuqina okwenzeka ku-[ Super- Umhlaba uphindwe kane kuya kasithupha ubukhulu boMhlaba],” kuphetha leli phephandaba.
U-Krauss nozakwabo bakwazile ukulingisa izimo zangaphakathi ze-super-Earths ngokutadisha ukuziphatha kokuncibilika kwensimbi ngengcindezi ye-gigapascals engu-1,000 - cishe ingcindezi ephindwe kathathu enkabeni yoMhlaba. Ithimba lasebenzisa uchungechunge lwama-lasers ukucindezela i-milligram encane. yezingcezu zensimbi kuya kungcindezi ephakeme nangaphezulu.
Ukuhlola kubonise ukuthi kuma-gigapascals angu-1 000, izinga lokushisa lokuncibilika kwensimbi lingaba ngu-11,000 degrees Celsius. Uma kuqhathaniswa, ukucindezela kwangaphakathi koMhlaba cishe ku-330 gigapascals, futhi izinga lokushisa lokuncibilika komnyombo wawo lingaba ngu-6,000 degrees Celsius.
"Lesi isilingo sokuqala sokulinganisa ijika lokuncibilika kwensimbi lapho kunengcindezi engaphezu kuka-290 GPa, okusho ukuthi ingeyokuqala ukukhawulela izinga lokushisa lokuncibilika kwensimbi ngaphansi kwezimo eziwumgogodla woMhlaba," u-Krause etshela u-El Reg.
“Izazi zezinkanyezi zizosebenzisa le miphumela, kanye nokuphawula kwazo, ukuze zenze imephu kangcono okwenzeka ngaphakathi nakuma-exoplanets.”®
