Kubva pakutanga kwa2017 kuvepo kwe TRAPPIST-1 Mazhinji anga ari iwo mashoko akasvika kwatiri nezve mukana wekuti imwe nzira yehupenyu inogona kuvamo, nekuda kwehunhu hwayo, kunyangwe, nguva pfupi yapfuura, zvese izvi zvinoratidza, kuvadaidza neimwe nzira, zvakaratidzwa zvishoma nezvishoma kuti, kana ivo havana kukwana zvakakwana kana, mushure mekuferefetwa kwakasiyana, vakaratidzirwa kuti havagone kuitika.
Kunyangwe zvakadaro, nhasi ndinoda kukuudza nezvekutsvaga kutsva kunogona kuve nhau huru. Sekureva kwevakasiyana vadzidzi uye nyanzvi dzekutsvagisa, sezviri pachena iyi solar system iri makore asingasviki makumi matatu nemasere kubva pasi, hachina chete mapuraneti ari munzvimbo iyoyo umo hupenyu hunogona kuvapo uye hune mvura, asi ikozvino zvakangoonekwa kuti, sezviri pachena, imwe yemapuraneti aya ine musimboti wesimbi, chinodikanwa chakakosha pakuvapo kwehupenyu.
TRAPPIST-1 ine nyika ine dense musimboti, hunhu hwakakosha kuti ugone kugashira hupenyu
Pakati pezvishoma zvatinoziva nezve TRAPPIST-1 nhasi, tinokuudza kuti tiri kutaura pamusoro pevhudzi dema rerudzi M, nyeredzi yaisazopenya kupfuura zuva redu uye kuti, nekuda kweizvi, nzvimbo yaro yekugara iri padyo it. Sekureva kwevamwe nyanzvi, sezviri pachena chokwadi chekuti nzvimbo ino yehupenyu iri padyo nezuva zvinokonzeresa kuti matambudziko akati wandei aoneke kuti hupenyu huvepo sezvahuri coupling tidal, chiitiko chinoita kuti nguva dzekutenderera nedzedudziro dzienzane, zvinoreva kuti mativi ese epasi ari pachena kuzuva iri zvachose. Rimwe dambudziko hombe rine chekuita nekuswedera padhuze kweimwe neimwe yemapuraneti ane zuva rayo uye iyo tembiricha yepamusoro.
Pamusana chaipo pezvinetso izvi, pakati pevamwe, vaongorori vanoshanda pakudzidza uye kuumbwa kweTrAPPIST-1 vafunga kutarisisa pane zvavanotenda kuti ndiwo mapuraneti maviri anopa hupenyu hwakareba kwazvo, TRAPPIST-1d uye TRAPPIST-1e. Nanhasi, zvese zvidzidzo zviri kuitwa pamapuraneti aya zvine chinangwa chekugona tsvaga kana imwe yeaya mapuraneti ane magnetosphere ine simba rakaringana kuti igone kushanda sedziviriro kubva kumwaranzi inoburitswa nenyeredzi yavanotenderera, uye nekuda kweizvi vanofanirwa kuve neyakagomarara.
Munguva yekutsvaga kwekupedzisira kuri kuitiswa pamapuraneti ataurwa pamusoro, boka revazivi venyeredzi kuColumbia University rakangofunga kuti TRAPPIST-1e ine dense core pamwe yakaumbwa nesimbi zvinhu zvakafanana, nekudaro, kune musimboti wePasi. Musimboti uyu unenge uri injini yemagineti ine simba inogona kuchengetedza pamusoro peTrAPPIST-1e kubva kumarambi ezuva anoburitswa nenyeredzi inotenderera.
Vazivi venyeredzi vangaziva sei zvechokwadi kana exoplanet ine demo simbi senge yepasi pachinhambwe chemakore makumi matatu nemapfumbamwe?
Nokuda kweizvi ndinoda kutaura mazwi evazivi venyeredzi Gabrielle Englemenn-Swiss y David kipping:
Kana iwe uchiziva huremu uye nharaunda yepasi zvakanyatsonaka, sezvakaita neTrAPPIST-1 system, unogona kuenzanisa iro data nemhando yezvinyorwa zvemukati mechimiro. Dambudziko nderekuti iwo mamodheru anowanzo kuve nematanho mana anogona kuita: simbi simbi, jasi re silicate, rukoko rwemvura, uye hamvuropu isina kujeka. Pasi rine maviri chete ekutanga, mhepo yaro haibatsiri zvakanyanya kuwanda kana nharaunda. Mune mamwe mazwi, isu tine vana vasingazivikanwe uye maviri chete anozivikanwa akasiyana. Mukutaura, idambudziko risingagadzirisike.
Asi isu takasarudza imwe nzira yekuverenga nayo. Isu tinotanga kubva kuchinhu chakapihwa huremu uye nharaunda, hakugone kuve nemhando dzine nuclei diki pane X dzinotsanangura iyo yakacherechedzwa mashoma uye nharaunda. Iyo nucleus inogona kukura kupfuura X, asi zvirinani inofanira kunge iri X, nekuti hapana yemhando yezvidzidzo inogona kuzvitsanangura neimwe nzira. Musiyano X unowirirana nezvatinogona kudaidza kuti chidimbu chepakati nepakati redhiyo. Saka isu tinotamba iwoyo mutambo kuti tione iwo wakanyanya muganho.
