Inzululwazi ayiyeki ukuzama ukufumana isijikelezi-langa esineempawu ezifana nesijikelezi-langa. Eyona njongo iphambili kukufumana iplanethi ekunokuhlalwa kuyo. Kule meko, ngonyaka we-2018 iplanethi yafunyanwa Kepler 1649c. Sisijikelezi-langa esineemeko ezifana kakhulu nezo zesi sijikelezi-langa sethu yaye sinokuhlaleka.
Kweli nqaku siza kukuxelela malunga neempawu kunye nezinto ezifunyenweyo ezenziwe nge-exoplanet Kepler 1649c.
i-exoplanet Kepler 1649c
I-Kepler Space Telescope yayeka ukusebenza ngoNovemba ka-2018, kodwa idatha ebonelelwe yi-observatory iyaqhubeka nokuhlolisiswa luluntu lwezenzululwazi, ngokuqwalasela okutyhila amagugu afihliweyo amaxesha ngamaxesha. Eyona nto imangalisayo yi-Kepler-1649c, i-exoplanet kwindawo ekunokuhlalwa kuyo yinkwenkwezi. Ngeli xesha, xa sisazi ngaphezu kwe-4.200 exoplanets, ezininzi zazo zikwindawo yokuhlala, sinokuzibuza: Yintoni ekhethekileyo nge-Kepler-1649c? Ewe, eyokuqala bubungakanani bayo. I-Kepler-1649c iphinda-phindwe nge-1,06 ubukhulu boMhlaba. Ngamanye amazwi, sisijikelezi-langa esisemhlabeni kwindawo ekunokuhlalwa kuyo. Inkwenkwezi yayo luhlobo olubomvu lwe-M olune-20% kuphela yobunzima beLanga, ngoko ke indawo ekunokuhlalwa kuyo yenkqubo ikufutshane kakhulu kwenkwenkwezi.
Enyanisweni, ixesha lokujikeleza kweKepler-1649c ziintsuku eziyi-19,5 kuphela (malunga ne-15 yezigidi zeekhilomitha). Nangona ijikeleza ikufutshane kangaka, inobushushu obulinganayo obumalunga ne-234 Kelvin kwaye yenza i-74% ye-energy flux efunyanwa nguMhlaba eLangeni. yafunyanwa nguKepler.
Kwakhona, kufuneka kugxininiswe ukuba i-Kepler-1649c yafunyanwa ngendlela yokuthutha, ngoko siyazi kuphela ubungakanani bayo kunye nexesha le-orbital. Inyani yokuba ikwindawo ekunokuhlalwa kuyo ayithethi ukuba inamanzi phezu kwayo; ekubeni ubukho beeoksidi zolwelo kwinto kuxhomekeke kwiiparamitha ezininzi ezingaziwayo (ubuninzi kunye nokwakheka kwe-atmospheric, ixesha lokujikeleza, ukuthambekela kwe-axis, umsebenzi wangaphakathi, njl.). Njengoko ukubhalwa kwayo kubonisa, i-Kepler-1649c yiplanethi yesibini efunyenwe kwinkqubo ye-Kepler-1649, emva kwe-Kepler-1649b, i-8,7-day-Earth-size iplanethi ubukho bayo buqinisekisiwe ngaphambili. Ngoko ke, i-exovenus.
Indawo ye-exoplanet Kepler 1649c
Iindlela zeKepler-1649b kunye neKepler-1649c zikwi-9: 4 resonance, kodwa le resonance ibuthathaka kakhulu, ngoko ke. kunokubakho iplanethi yesithathu kwinkqubo engekafunyanwa, ibekwe phakathi kwezi planethi zimbini zifunyenweyo, kwaye omabini amazwe ehlabathi anxulumene nale planethi yokucingela iku-3: 2 resonance. Ekubeni kungekho miqondiso yesi sijikelezi-langa sesithathu kwiinkcukacha ze-Kepler, oko kuthetha ukuba incinane kunoMars okanye inqwelo-moya yayo ejikelezayo inotyekelo olwahlukileyo kwaye ayikwazi ukudlula elangeni njengoko ibonwa eMhlabeni.
Nangona kunjalo, yintoni enomdla ngokwenene malunga ne-Kepler-1649c kukuba ifunyenwe kulo nyaka ngokuhlalutya idatha evela kwi-mission ye-Kepler ephambili efunyenwe phakathi kwe-2010 kunye ne-2013. Ngo-2014, umviwa onokwenzeka we-exoplanet okanye i-KOI (i-Kepler Object of Interest) yafunyanwa. ) ngeenxa zonke inkwenkwezi ebizwa KOI 3138.01. Uhlalutyo olulandelayo lwejiko lokukhanya leplanethi yomgqatswa usebenzisa isoftware ethile ebizwa ngokuba yiRobovetter yaqinisekisa ngo-2017 ukuba yayiyiplanethi yokwenyani kwaye yabizwa ngokuba yiKepler-1649b. Nangona kunjalo, U-Robovetter ugwebe omnye umgqatswa we-exoplanet onokwenzeka, i-KOI 3138.02, njengobuxoki.. Uphononongo olutsha lwe-KOI 3138.02 liqela leenkwenkwezi ezikhokelwa ngu-Andrew Vanderburg lubonisa ukuba yiplanethi yokwenene emva kwayo yonke into: Kepler-1649c. Konke kungenxa yokuba ijika elikhanyayo le-KOI 3138.02 labamba ingqalelo yabantu ababehlalutya ngokubonakalayo idatha ye-Kepler. Oku kuthetha ukuba, kwelinye icala, izinto ezikhatywayo njengezinto ezingeyonyani zisenokuzifihla ii-exoplanets ezimbalwa zokwenyani kwaye, kwelinye icala, ukuhlolwa kwabantu okubonakalayo kuseyinzuzo enkulu kule ndawo.
Enye into enomdla ye-Kepler-1649c yileyo sisijikelezi-langa sokuqala esinokuhlaleka esifunyenwe phakathi kwezilwanyana ezincinci ezimdaka ngobungakanani ezijongwe nguKepler. Eyona nto iphambili ekujoliswe kuyo nguKepler ziinkwenkwezi zohlobo lwelanga, kodwa iphinde yabona iindawo ezininzi ezibomvu kwindawo yayo yokujonga. Nangona iincinci ezibomvu zibonakala zingenakukwazi ukuhlalwa kuzo kuneenkwenkwezi zohlobo lwelanga ngenxa yokukhanya okuphezulu kwe-ultraviolet kunye nokuthambekela kwazo ukukhupha amadangatya amakhulu, amanani azo kunye nobomi obude buthetha ukuba, ngokweemeko ezinokwenzeka, kufuneka kubekho iiplanethi ezinokuhlalwa ngakumbi. Ukuchaneka, siyayazi ngokwedatha ye-Kepler ukuba, ngokwe-avareji, i-dwarf nganye ebomvu ineeplanethi ezingaphezulu kwezimbini ezincinci kuneNeptune kwaye zinexesha elingaphantsi kweentsuku ezingama-200. Ngapha koko, zininzi ii-asteroids ezifumaneka kwindawo ezingqonge ii-dwarfs ezibomvu kuneenkwenkwezi zohlobo lwelanga.
Iplanethi ekunokuhlalwa kuyo
I-Kepler-1649c ayisiyiyo kuphela esondele kakhulu elingana noMhlaba ngokobukhulu kunye nesixa samandla esiwafumana kwenkwenkwezi yawo, kodwa inikeza umbono omtsha ngokupheleleyo weenkqubo zasekhaya. Ngamaxesha alithoba apho iiplanethi ezingaphandle zenkqubo zijikeleza inkwenkwezi yazo, iiplanethi ezingaphakathi zijikeleza phantse izihlandlo ezine.
Inyaniso yokuba ii-orbits zabo zihambelana kubudlelwane obuzinzile bubonisa ukuba inkqubo ngokwayo izinzile kwaye inokubakho ixesha elide.
Phantse ulungelelwaniso lwexesha eligqibeleleyo ngokubanzi Zibangelwa yinto ebizwa ngokuba yi-orbital resonance., kodwa umlinganiselo wesithoba ukuya kwezine wahlukile ngokwentelekiso kwiinkqubo zezijikelezi-langa. Ngokuqhelekileyo, i-resonance iyenzeka ngendlela yobudlelwane phakathi kwababini-nye okanye abathathu ukuya kwababini. Nangona kungaqinisekiswanga, ukungaqhelekanga kobu budlelwane kunokucebisa ubukho beplanethi ephakathi, kunye neeplanethi zangaphakathi kunye nezangaphandle ezijikelezayo ngokuvumelanisa, ukudala i-resonance enye-ezintathu-ezimbini.
Njengoko unokubona, inzululwazi ayiyeki ukuzama ukufumana izijikelezi-langa ezifana nezethu ezikwiimeko ukuze zibone ukuba zinokuhlaleka na okanye akunjalo. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-exoplanet Kepler 1649c kunye neempawu zayo.
