Moyo pa Super-Earths ukhoza kukhala ndi nthawi yochulukirapo yopangira ndi kusinthika chifukwa cha mphamvu zawo zamaginito zomwe zimawateteza ku kuwala koopsa kwa zakuthambo, malinga ndi kafukufuku watsopano wofalitsidwa m'magazini ya Science.
Malo ndi malo owopsa. Mitsinje ya tinthu tating'onoting'ono tokhala pafupi kwambiri ndi liwiro la kuwala, zotulutsidwa kuchokera ku nyenyezi ndi milalang'amba yakutali, mapulaneti a bombard. Ma radiation amphamvu amachotsa mlengalenga ndikupangitsa kuti nyanja zapadziko lapansi ziume pakapita nthawi, ndikupangitsa zouma komanso zosatha kukhala ndi moyo.Komabe, kuwala kwa chilengedwe kumapatuka kuchoka pa Dziko Lapansi chifukwa kumatetezedwa ndi mphamvu yake ya maginito.
Tsopano, gulu la ofufuza motsogozedwa ndi Lawrence Livermore National Laboratory (LLNL) akukhulupirira kuti super-Earths - mapulaneti aakulu kwambiri kuposa Dziko Lapansi koma osachepera Neptune - angakhalenso ndi maginito. kuposa omwe ali padziko lapansi, kutanthauza kuti moyo pamalo awo ukanakhala ndi nthawi yochuluka yoti ukhale ndi moyo.
"Ngakhale pali zofunikira zambiri za dziko lapansi, monga kutentha kwapamwamba komwe kungathe kupanga madzi amadzimadzi, kukhala ndi magnetosphere yomwe imatha kupirira kutentha kwa dzuwa kwa nthawi yaitali kungapereke nthawi yotalikirapo kuti moyo usinthe," adatero Richard. pepala.Wolemba wamkulu Krause, wasayansi ku LLNL, adauza The Register.
Chinsinsi cha mphamvu ya maginito yosalekeza ndi kukhala ndi chitsulo chamadzimadzi chomwe chimazizira pang'onopang'ono. Mphamvu ya maginito ya dziko lapansi imapangidwa ndi chitsulo chosungunuka chomwe chimazungulira pakatikati pachitsulo cholimba. mphamvu maginito.
Komabe, kutentha kwachitsulo chosungunula chokwiriridwa pamtunda wa makilomita 2,890 kapena makilomita 1,800 pansi pa Dziko Lapansi kukuzizira kwambiri. Kumazizira mpaka kukhazikika.Panthawiyi, jenereta yake yamkati idzasiya kupota ndipo silingathenso kuchirikiza mphamvu ya maginito. mphamvu ya maginito idzazimiririka pafupifupi zaka 6.2 biliyoni.
“Chitsulocho chikalimba, chimatulutsa mphamvu ndi zinthu zopepuka muzitsulo zamadzimadzi, zomwe zimapatsa mphamvu jenereta kwa nthawi yayitali.Panthawi ina, kutentha kwa madzi amadzimadzi kumazizira mpaka kutentha kusungunuka, zomwe zikutanthauza kuti idzayamba kuzizira, "adatero Klaus. Chitsulo chomwe chili mkati mwa dziko lapansi chimakhala cholimba kwambiri kuposa dziko lapansi, ndipo chimasungunukanso pamtunda wapamwamba kwambiri. kutentha.
Mwa kuyankhula kwina, phata la super-Earth liyenera kuzizira mpaka kutentha pang'ono kwambiri lisanakhazikike.Maziko awo akuluakulu amatanthauzanso kuti amachotsa kutentha pang'onopang'ono kuposa Dziko lapansi.
"Tinapeza kuti maziko apamwamba adzalimbitsa 30% nthawi yayitali kuposa pachimake ... Dziko lapansi liri kuwirikiza kanayi kapena kasanu ndi kulemera kwa Dziko Lapansi],” inatero nyuzipepalayo.
Krauss ndi anzake adatha kutsanzira mikhalidwe ya mkati mwa super-Earths pophunzira khalidwe losungunuka lachitsulo pa mphamvu ya 1,000 gigapascals - pafupifupi katatu kupanikizika kwapakati pa Earth. zidutswa zachitsulo kupita ku zipsyinjo zapamwamba komanso zapamwamba.
Mayesero asonyeza kuti pa 1,000 gigapascals, kutentha kwachitsulo kumakhala pafupifupi madigiri 11,000. Poyerekeza, kupanikizika kwapakati pa dziko lapansi ndi pafupifupi 330 gigapascals, ndipo kutentha kwapakati pake kumakhala pafupifupi 6,000 digiri Celsius.
"Uku ndi kuyesa koyamba kuyeza kusungunuka kwachitsulo pamakina opitilira 290 GPa, zomwe zikutanthauza kuti ndikoyamba kuchepetsa kutentha kwachitsulo pansi pazigawo zapakatikati," Krause adauza El Reg.
"Akatswiri a zakuthambo adzagwiritsa ntchito zotsatirazi, limodzi ndi zomwe akuwona, kuti adziwe bwino zomwe zikuchitika mkati ndi kunja kwa dziko."®
