Hupenyu huri pa-super-Earth hunogona kunge huine nguva yakawanda yekugadzira uye kushanduka nekuda kweanoramba ari magineti minda inovadzivirira kubva kune inokuvadza cosmic mwaranzi, sekureva kwechidzidzo chitsva chakaburitswa mujenari Science.
Muchadenga inzvimbo ine ngozi.Nzizi dzezvikamu zvinochaji zviri pedyo zvikuru nekumhanya kwechiedza, zvinobudiswa munyeredzi nemakwara enzou ari kure, mapuraneti anobhomba. Mwaranzi ine simba inobvisa mhepo uye inoita kuti makungwa ari pamusoro penyika aome nekufamba kwenguva. yakaoma uye isingakwanisi kutsigira hupenyu hunogarwa.Zvisinei, mwaranzi yemuchadenga inotsauswa kubva paNyika nekuti inodzivirirwa nemagetsi ayo.
Ikozvino, boka revatsvagiri rinotungamirwa naLawrence Livermore National Laboratory (LLNL) rinotenda kuti super-Earths - mapuraneti akakura kupfuura Earth asi ari pasi peNeptune - anogona zvakare kunge aine magineti. kupfuura avo vakatenderedza Pasi, zvichireva kuti hupenyu pazviso zvavo hwaizova nenguva yakawanda yekukudziridza uye kurarama.
"Kunyange paine zvakawanda zvinodikanwa zvepasi rinogara, senge tembiricha yepamusoro inokwanisa kugadzira mvura yemvura, ine magnetosphere inokwanisa kumira nemwaranzi yezuva kwenguva yakareba inogona kupa nguva yakareba yekuti hupenyu huvepo," Richard akadaro nezve. bepa.Mutungamiriri munyori Krause, nyanzvi yefizikisi kuLLNL, akaudza The Register.
Chinokosha kusimba remagineti rinoramba riripo kuva nesimbi yemvura inotonhorera inotonhora zvishoma nezvishoma.Magineti ePasi anogadzirwa nesimbi yakanyunguduka inotenderera ichitenderedza musimboti wesimbi wakasimba.Maelectrons ari mumvura anofamba kugadzira magetsi anoenderera mberi. simba remagineti.
Zvisinei, tembiricha yesimbi yakanyungudutswa yakavigwa makiromita 2,890 kana mamaira 1,800 pasi pePasi pevhu iri kutonhora.Inozopedzisira yatonhodza kusvika yanyatsogadzirwa.Panguva iyi, jenareta rayo remukati richamira kutenderera uye harichakwanisi kutsigira magnetic field.Earth's magnetic field ichanyangarika mumakore anenge mabhiriyoni 6.2.
“Ani painoomesa, inobudisa simba uye zvinhu zvakareruka kupinda musimbi yemvura, iyo inopa simba mujenareta kwenguva yakareba.Pane imwe nguva, tembiricha yepakati pemvura inotonhora kusvika pakunyunguduka, zvinoreva kuti ichatanga kutonhora. tembiricha.
Nemamwe manzwi, the super-Earth's core inoda kutonhodza kusvika pakadzika tembiricha isati yaoma.Makore awo akakura zvinorevawo kuti anobvisawo kupisa zvishoma nezvishoma kupfuura Earth.
"Takaona kuti super core ichasimbisa 30% kureba kupfuura musimboti ... Nekuda kwemakwikwi emhedzisiro yesimba rakachengetwa uye nzvimbo yepasi, macores emapuraneti madiki pane Earth achasimba nekukurumidza, nenguva yakareba kwazvo yekusimba inoitika pa[ Super- Pasi rinopeta nekana kana katanhatu ukuru hwePasi],” bepa racho rakagumisa kudaro.
Krauss nevamwe vake vakakwanisa kutevedzera mamiriro emukati meiyo super-Earths kuburikidza nekudzidza maitiro ekunyunguduka kwesimbi pakumanikidzwa kwe1,000 gigapascals - inopeta katatu kudzvanywa kwepakati pePasi. yezvimedu zvesimbi kune yakakwirira uye yakakwirira kudzvinyirirwa.
Ongororo dzakaratidza kuti pa1,000 gigapascals, kunyunguduka kwesimbi kunenge 11 000 madhigirii celsius. Kana tichienzanisa, kumanikidzwa kwepasi kwePasi kunosvika 330 gigapascals, uye kunyunguduka kwepakati payo kunosvika 6,000 degrees Celsius.
"Uku ndiko kuyedza kwekutanga kuyera kunyunguduka kwesimbi pakumanikidza kunodarika 290 GPa, zvinoreva kuti ndiyo yekutanga kudzikamisa tembiricha yekunyunguduka kwesimbi pasi pemamiriro epamusoro-soro ePasi," Krause akaudza El Reg.
“Vazivi venyeredzi vachashandisa mhedzisiro iyi, pamwe nezvavanoona, kuita mepu zvirinani zviri kuitika mukati nekunze kwenyika.”®
