Siyazi ukuba indalo iphela ayinasiphelo yaye umntu uye wakufumanisa kunzima ukufumana nantoni na eyongezelelekileyo. Enye yee-exoplanets yafumanisa ukuba itsala ingqalelo eninzi kwizazinzulu yi I-J1407b. Yiplanethi efumaneka kwinkqubo yeenkwenkwezi i-J1407, ebekwe malunga nama-434 eminyaka yokukhanya kude noMhlaba. Le planethi idale umdla omkhulu kwizazi ngeenkwenkwezi kunye nabalandeli bendawo ngenxa yeempawu zayo ezizodwa nezingaqondakaliyo.
Ngoko ke, siza kunikezela eli nqaku ukukuxelela malunga neempawu, ukufumanisa kunye nezinto ezinomdla kwiplanethi i-J1407b.
Iimpawu eziphambili
Eyona nto itsala umdla wesi sijikelezi-langa kuluntu lwenzululwazi yinkqubo yayo yeringi enkulu ngokungaqhelekanga nentsokothileyo. Iiringi zale planethi zikhulu kakhulu kwaye zikhulu kakhulu kunezo zeSaturn. Ubungakanani besangqa seJ1407b siqikelelwa ukuba simalunga ne-120 yezigidi zeekhilomitha. elilingana nomgama omalunga nama-200 omgama phakathi koMhlaba neNyanga. Ezi zangqa zenziwe ngamasuntswana amaninzi, ukusuka kumaqhekeza amancinci ukuya kwizinto ezilingana nenyanga.
Yiplanethi ebonisa ukuguquguquka okukhulu kwisakhiwo samakhonkco ayo. Uphononongo lubonakalise ukuba izangqa zayo zibonisa iimpawu eziguqukayo ekuhambeni kwexesha. Oku kubonisa ukuba kunokubakho iinyanga okanye ii-exomoons ezijikeleza iplanethi, unxibelelwano lwalo lomxhuzulane luguqula imilo yezangqa. Esi siganeko siphakamisa imibuzo emininzi malunga nokubunjwa kunye nokuvela kweenkqubo zeplanethi, kwaye kuye kwakhokelela kwiingcamango ezinomdla malunga nokuba khona kwee-exomoons ezihlala kuyo kwi-J1407b.
Ngokumalunga nobukhulu bomzimba weplanethi iJ1407b, Imalunga nama-20 inkulu kuneJupiter, esi sijikelezi-langa sikhulu kwisixokelelwano sethu sezijikelezi-langa. Ubunzima bayo obuchanekileyo abukachazwa ngokuthe ngqo, kodwa kuqikelelwa ukuba buphindaphindwe kaninzi kuneJupiter. Ngaphaya koko, umjikelo we-J1407b ojikeleze inkwenkwezi i-eccentric kakhulu, nto leyo ethetha ukuba umgama wayo ukusuka kwenkwenkwezi yayo uyahluka kakhulu kwixesha layo lokujikeleza. Konke oku kunokuchaphazela imozulu kunye neemeko zomoya.
Ukufunyanwa kweplanethi i-J1407b
Kwi-2012, isazi ngeenkwenkwezi saseYunivesithi yaseRochester u-Eric Mamajek kunye neqela lakhe babe ngabokuqala ukuchaza ukufunyanwa kwenkqubo ye-J1407 kunye ne-eclipses ekhethekileyo. Ukususela kwinkqubo yeringi ejikeleze i-J1407b, i-substellar iqabane, yafunyanwa ngokuqwalasela Ukusithwa kwelanga yinyanga okude nokuntsonkothileyo kwenkwenkwezi i-J1407 ngexesha leentsuku ezingama-56 ngo-Epreli nangoMeyi ka-2007.
I-J1407b yayibhalwe "i-Super Saturn" okanye "i-Saturn kwi-steroids" ngenxa yenkqubo yayo ye-ring circumplanetary. Umzimba ojikelezayo unobunzima obuqikelelweyo obufana nobomhlaba, kwaye unokuqinisekiswa ngokuqiniseka okungaphezulu kwe-99% ukuba ayiyonkwenkwezi enobunzima obungaphezulu kwe-80 ye-Jupiter.
Kwi-2007, ulandelelwano lwe-occultations lenkwenkwezi 1SWASP J140747.93-394542.6 yabonwa ngeentsuku ze-56, nto leyo eyakhokelela ekubhaqweni kwe-J1407b, i-exoplanet yokuqala enenkqubo yeringi. Inkqubo ye-multi-ring pattern yayihambelana nenkqubo enkulu yeplanethi kwaye yayine-radius yangaphandle engama-640 ngamaxesha e-Saturn. Iqela lophando liphinde lachonga izikhewu kwiindandatho, ezibonisa ubukho be-exomoons, okanye iisathelayithi, ezenziwe kwaye zaqokelelwa kwizinto ezijikelezayo ze-J1407b. Nangona kunjalo, xa kujongwa ubudala benkqubo yeenkwenkwezi (iminyaka eyi-16 yezigidi kuphela) kunye nobukhulu obukhulu benkqubo yeringi (Ubunzima boMhlaba bulingana), iingcali zikholelwa ukuba kunokwenzeka ukuba ibe yidiski ye-circumplanetary okanye i-protoexosatellite kwinkqubo. kunenkqubo yendandatho ezinzileyo kwinkqubo yeplanethi evuthiweyo njengamakhonkco eSaturn.
Ulwazi malunga neendandatho zeplanethi J1407b
Njengoko ipapashwe yi-Leiden Observatory kunye neYunivesithi yaseRochester iinkokeli zokufumanisa, le planethi inamakhonkco angama-37. Eli nani lemisesane lingaphezulu kakhulu kunokuba bekucingelwa ekuqaleni. Nganye kwezi zangqa inobubanzi obungamakhulu eekhilomitha ezingama-10,000, eyenziwe yinto emnyama kakhulu ethintela phantse konke ukukhanya okuvela kwenkwenkwezi. Olu phawu lwalungundoqo ekubhaqweni kwayo.
Kukho umngxuma omkhulu kobo bunzima bezangqa, obunokubonisa ubukho benyanga. Kwaye eso sakhiwo ngenene yidiski yokwandisa kwihlabathi kwinkqubo yokwakheka. Inyaniso, Ayinakuba yiplanethi kwaye ikhukuliseke ibe yintsundu emdaka., apho izinto ezibonakala ngoku njengendandatho ziphela ngokuyinxenye okanye zinyamalale ngokupheleleyo.
Okwangoku, abaphandi bakhuthaza izazi ngeenkwenkwezi ezifunda ngeenkwenkwezi ukuba zibeke iliso kugqabhuko-dubulo lwasempuma ukwenzela ukusithwa kwelanga yinyanga okulandelayo, ngokusekelwe ekubeni banokufunda ngakumbi ngayo.
Eminye iminqweno
Ukongeza kuphando malunga nezangqa, kukho ingqikelelo yokuba i-J1407b igcina iimpawu eziphawulekayo ze-atmospheric. Nangona ukubunjwa kwe-atmospheric yayo akukaqinisekiswa, izazinzulu ziye zenza uphando kunye nokulinganisa ukuqonda ngcono iimeko zemozulu ezinokwenzeka kule planethi ikude.
Kukholelwa ukuba inokuba nomoya otyebileyo kwizinto ezifana ne-hydrogen kunye ne-helium, efana ne-gas giants kwisixokelelwano sethu selanga. Nangona kunjalo, kuye kwachazwa malunga nobukho bezinto ezinzima, ezifana ne-methane kunye ne-ammonia, ethi zinokunika imibala eyahlukileyo kunye neepateni kwiatmosfera yakho. Ezi zixhobo ze-atmospheric ziyakwazi ukusebenzisana nokukhanya kwelanga ngeendlela ezimangalisayo kwaye zifake isandla kwiinguqu ezikhanyayo ezibonwa kwi-J1407b.
Enye yezona zinto zinomdla kakhulu kwesi sijikelezi-langa kukwazi kwayo ukusingatha iinyanga okanye ukuphuma kwe-exomoons kwi-orbit ejikelezayo. Ukusebenzisana komxhuzulane phakathi kweplanethi kunye nezi nyanga ezicingelwayo ingaba nempembelelo ebalulekileyo kwisakhiwo samakhonkco, kunye neemeko zemozulu zeplanethi ngokwayo. Ukuba ii-exomoons ezinokuhlala zikhona kwi-J1407b, zinokubonelela ngemekobume enokuthi ilungele ubomi, zikhulise umdla wokufunda ngakumbi malunga neplanethi.
Ndiyathemba ngolu lwazi unokwazi ngakumbi malunga ne-J1407b kunye neempawu zayo.
