Uranus \u0219i Neptun s-ar putea s\u0103 nu fie \u201egigan\u021bii de ghea\u021b\u0103\u201d clasici pe care oamenii de \u0219tiin\u021b\u0103 i-au considerat mult timp, potrivit unui nou studiu al Universit\u0103\u021bii din Zurich, scrie SciTechDaily<\/a><\/span>.<\/p>\n

Rezultatele sugereaz\u0103 c\u0103 ambele planete \u00eendep\u0103rtate ar putea con\u021bine mult mai mult material st\u00e2ncos dec\u00e2t se presupunea anterior, schimb\u00e2nd perspectivele asupra structurii lor interne.<\/p>\n

Reevaluarea etichetei de \u201egigant de ghea\u021b\u0103\u201d<\/h2>\n

\u00cen mod tradi\u021bional, planetele din Sistemul Solar sunt \u00eemp\u0103r\u021bite \u00een lumi st\u00e2ncoase, gigan\u021bi gazo\u0219i \u0219i gigan\u021bi de ghea\u021b\u0103.<\/p>\n

Uranus<\/a><\/span> \u0219i Neptun au fost inclu\u0219i \u00een categoria gigan\u021bilor de ghea\u021b\u0103 pe baza unor modele care indicau un interior dominat de ap\u0103 \u0219i alte tipuri de ghea\u021b\u0103.<\/p>\n

Noul studiu, publicat \u00een revista Astronomy & Astrophysics, sus\u021bine \u00eens\u0103 c\u0103 aceast\u0103 clasificare este prea simplist\u0103 \u0219i propune c\u0103 structurile interne bogate \u00een roc\u0103 r\u0103m\u00e2n o posibilitate plauzibil\u0103.<\/p>\n

Cercet\u0103torii indic\u0103 planeta pitic\u0103 Pluto, despre care se \u0219tie acum c\u0103 este \u00een mare parte st\u00e2ncoas\u0103, drept dovad\u0103 c\u0103 obiectele din exteriorul Sistemului Solar nu urmeaz\u0103 \u00eentotdeauna tiparele a\u0219teptate.<\/p>\n

O nou\u0103 metod\u0103 de modelare a interiorului planetar<\/h2>\n

Pentru a testa compozi\u021bii alternative, echipa de cercetare a dezvoltat o abordare hibrid\u0103 de modelare, care combin\u0103 metode bazate pe fizic\u0103 \u0219i date empirice.<\/p>\n

\u00cen loc s\u0103 porneasc\u0103 de la materiale prestabilite, modelele genereaz\u0103 profile de densitate aleatorii, constr\u00e2nse de m\u0103sur\u0103tori gravita\u021bionale reale.<\/p>\n

Prin rularea a mii de simul\u0103ri, oamenii de \u0219tiin\u021b\u0103 au identificat structuri interne care corespund cel mai bine datelor observate.<\/p>\n

Autorul principal, Luca Morf, afirm\u0103 c\u0103 aceast\u0103 abordare evit\u0103 prejudec\u0103\u021bile, r\u0103m\u00e2n\u00e2nd \u00een acela\u0219i timp realist\u0103 din punct de vedere fizic \u0219i oferind o gam\u0103 mai larg\u0103 de scenarii posibile.<\/p>\n

C\u00e2mpurile magnetice \u0219i necesitatea unor misiuni viitoare<\/h2>\n

De asemenea, modelele ofer\u0103 perspective noi asupra c\u00e2mpurilor magnetice neobi\u0219nuite ale celor dou\u0103 planete, foarte diferite de structura magnetic\u0103 a P\u0103m\u00e2ntului.<\/p>\n

Ambele planete par s\u0103 aib\u0103 straturi de \u201eap\u0103 ionic\u0103\u201d, capabile s\u0103 genereze c\u00e2mpuri magnetice complexe la ad\u00e2ncimi diferite.<\/p>\n

Cu toate acestea, persist\u0103 incertitudini din cauza \u00een\u021belegerii limitate a comportamentului materialelor \u00een condi\u021bii extreme de presiune \u0219i temperatur\u0103.<\/p>\n

Cercet\u0103torii concluzioneaz\u0103 c\u0103 sunt esen\u021biale misiuni dedicate c\u0103tre Uranus \u0219i Neptun pentru a stabili dac\u0103 aceste lumi sunt bogate \u00een ghea\u021b\u0103, \u00een roc\u0103 sau se situeaz\u0103 undeva \u00eentre aceste extreme.<\/p>\n","protected":false},"excerpt":{"rendered":"
