Gulu lapadziko lonse lapansi la akatswiri azakuthambo, kuphatikiza ofufuza a Institute of Astrophysics of the Canary Islands (IAC), apeza zaka zowala 200 kuchokera kwa ife dongosolo la mapulaneti asanu ndi limodzi, asanu mwa iwo akuvina modabwitsa kuzungulira nyenyezi yawo yapakati, TOI-178 .
Komabe, sizinthu zonse zomwe zimagwirizana. Mosiyana ndi dzuwa lathu, momwe mamembala ake amawonekera bwino molamulidwa ndi kachulukidwe, ndi Dziko lapansi ndi miyala yamiyala mkati ndi zimphona zakunja kunja, pakadali pano mapulaneti osiyanasiyana akuwoneka kuti akusakanikirana mwachisokonezo.
Dongosolo la mapulaneti lazaka 7.1 biliyoni komanso zotsutsana, zomwe zafotokozedwa munyuzipepalayi “Kupenda Zakuthambo & Kupenda Nyenyezi”, Imatsutsa chidziwitso cha asayansi momwe makina amapangidwira ndikusintha.
Ngakhale asayansi awona chodabwitsachi chomwe chimadziwika kuti resonance m'mbuyomu m'mapulaneti ena, aka ndi koyamba kuti mapulaneti omwewo asiyane wina ndi mnzake.
Ofufuzawa adagwiritsa ntchito telescope ya space ya European Space Agency ya CHEOPS kuti azindikire mapangidwe achilendowa. Akatswiriwa anapeza kuti mapulaneti asanu mwa asanu ndi limodziwo atsekeredwa motsatira kayendedwe ka harmonic, komwe kumazungulira kwawo kumakhala kofanana mofanana.
Mapulaneti asanu akunja ali munthawi yofananira ndi 18: 9: 6: 4: 3. Kuwonjezeka kwa 2: 1 kungawonetse kuti pakuzungulira kulikonse kwa pulaneti lakunja, lamkati limapanga awiri. Pankhani ya TOI-178, izi zikutanthauza kuvina kovuta pamunsi pansipa:
Kuchuluka kwa mapulaneti m'dongosolo ndizachilendo. M'malo ozungulira dzuwa, mapulaneti olimba kwambiri ali pafupi kwambiri ndi Dzuwa, ndikutsatiridwa ndi zimphona zowala kwambiri. Pankhani ya TOI-178, pulaneti yofanana ndi Dziko lapansi ili pafupi ndi pulaneti yonyentchera yokhala ndi theka lakulimba kwa Neptune, lotsatiridwa ndi lofanana ndi la Neptune. Kapangidwe kodabwitsa kameneka pamodzi ndi kamvekedwe kake kameneka "kamatsutsa zomwe tikudziwa momwe mapulaneti amapangira," malinga ndi olembawo.
"Kuzungulira kwadongosolo lino kulamulidwa bwino, zomwe zikutiuza kuti dongosololi lakhala likuyenda bwino kuyambira pomwe lidabadwa," akufotokoza Yann Alibert waku University of Bern komanso wolemba nawo ntchitoyi.
M'malo mwake, chiwonetsero cha dongosololi chikuwonetsa kuti sichinasinthe kuyambira pomwe chidapangidwa. Zikanakhala kuti zidasokonekera kale, mwina chifukwa cha mphamvu yayikulu kapena mphamvu yokoka ya kachitidwe kena, kusanja kosalimba kwa njira zake zikadafafanizidwa. Koma sizinakhale choncho.
“Aka ndi koyamba kuti tiziwona zotere. M'dongosolo lochepa lomwe timadziwa ndikugwirizana koteroko, kuchuluka kwa mapulaneti kumatsika nthawi zonse tikamachoka ku nyenyezi, " Anatero wolemba nawo ESA komanso wasayansi ya projekiti Kate Isaak.
