Hapana munhu akareba akashamiswa kaviri uye kunyange katatu nyeredzi masisitimu; Kune mamwe mapuraneti pasi pemaviri kana matatu ezuva. Nekudaro, masisitimu anosanganisira nyeredzi nhanhatu pakarepo anoramba asingawanzo. Kusvika nguva pfupi yadarika, chete 17 zvinhu zvakadaro zvave kuzivikanwa, uye tic 168789840 40 chave chegumi nemasere. Izvi zvinonzi muchinyorwa chitsva nevatambi veAmerica vakawana bhuku remagazini yezviyeu uye zvinokwanisika mune yakavhurika yebhandi ROLIG Raibhurari ArXIV.
Tic 168789840 iri mumapoka eboka reEridan, ari kure nemakore gumi nematanhatu emakore. Zvinosanganisira gravitationally chokuita yegwara nyeredzi, vaviri iyo (A uye C) zvinoumba "tsanga" wegadziriro, uye yechitatu (c) rotates vakavapoteredza kure muchadenga. Nyeredzi dzezvikamu zviviri uye zvichapfuura mumwe nemumwe mumazuva 1,6, iyo system c - mumazuva 1,3, uye mu 8.2. Nekudaro, iyo masisitimu pachavo a naC batai kwemakore mana epasi, uye nekukotama hurongwa hwavo mumakore maviri.
NASA ASTROPHYSCIST Brian Powell uye vaanoshanda navo Tic 168789840 nerubatsiro rweTesikopu vakafanana nenyeredzi dzakawanda dzakawanda neyezvitatu zvikamu - α mapatya). Nekudaro, matatu maviri eTic 16878984040 zvakafanana neyenono: Vese vanosanganisira nyeredzi yakakura ne radius ye1,2-1.3 Solar, pamwe neyakaoma, pamwe neyedukumuvhuvhu wediki .5 -07 solar uye 0.5-0.6 radius kubva musi wezuva.
Nyeredzi mbiri a uye c dzakanyanya pedyo, dzichigadzira runyararo rwakanyanya kuwanda, saka hazvibviri kufunga kuti mapuraneti anogona kuumbwa uye apone. Nekudaro, masayendisiti anoratidza kuti hurongwa hwakareba kure navo mupasi rinogona kunge riri. Vanyori vanoronga kuenderera mberi nekucherechedzwa kweti 168789840 uye, pamwe, kuwana nyika iri kure zvakadaro.
Iri basa rinoita kuti zvikwanisike kufunga kuti zvakanyatso kujairika masisitimu anoumbwa, kusanganisira nyeredzi dzakawanda sei. Inofungidzirwa kuti vanogona kuoneka seyenyedzi dzepakati dzakaumbwa pamwe chete - muzvose "cradle." Nekudaro, nekuenderera, achipfuura ne gore rakapepetwa-gasi, mumwe nemumwe wevatori vechikamu vemitemo akawana muvakidzani mutsva, achingoita kaviri. "Zvese izvi zvinongoshamisa," anodaro Brian Powell. "Ndinoshuva kuti dai ndisina nyeredzi, kuti ndimuise padhuze nepedyo uye tinoona zvese nemaziso angu."
