Thupi lakumwamba lomwe langopezedwa kumene, lotchedwa interstellar comet 3I/Atlas, likupita patsogolo ku Sistema Solar ndi liwiro lojambulidwa la makilomita 57 pamphindikati. Observações Kafukufuku waposachedwa wa zakuthambo amatsimikizira kuti chinthucho sichinayambike m’dera lozungulira dzuwa, koma m’dongosolo lakutali la nyenyezi, likuyenda mozama kwa zaka masauzande ambiri musanawoloke njira yapadziko lapansi pano.
Kuzindikiridwa kwa mlendo wa zakuthambo ndi chizindikiro cha nthawi yofunika kwambiri pa zakuthambo zamakono, kukhazikitsa 3I/Atlas monga chinthu chachitatu chotsimikizika chapakati pa nyenyezi kudutsa dera lathu lamlengalenga. Ma telesikopu olondola kwambiri amatsata njira ya comet tsiku lililonse, kupereka chidziwitso chofunikira pakuwerengera kwenikweni kwa kanjira kake komanso mawonekedwe ake enieni.
Mosiyana ndi zinthu zakuthambo zomwe zimazungulira Sol mozungulira, comet iyi ili ndi njira yodziwika bwino ya hyperbolic. Essa mawonekedwe a geometric amawonetsetsa kuti mphamvu yokoka ya nyenyezi yathu sikhala yokwanira kuigwira kapena kuisunga mozungulira, kuilola kuti ipitilize ulendo wake wopita ku malo a nyenyezi ikayandikira kwambiri.
Mphamvu za hyperbolic trajectory ndi liwiro la thupi lakumwamba
Kuthamanga kwambiri kwa 3I / Atlas ndi chimodzi mwazinthu zazikulu zomwe zimatsimikizira kuti zinachokera kunja kwa Sistema Solar. Enquanto ma comets am’deralo amafika pa liwiro lapamwamba pokhapokha pa perihelion, mlendo wa interstellar walowa kale mu heliosphere ndi mphamvu ya kinetic yapamwamba kwambiri kuposa liwiro la kuthawa kwanuko.
Pofuna kujambula zinthu zakuthambo, asayansi apanga mafananidwe achindunji pakati pa zinthu zitatu zapakati pa nyenyezi zomwe zimadziwika mpaka pano. Zomwe zimasonkhanitsidwa ndi mabungwe amlengalenga zikuwonetsa miyeso yeniyeni ya liwiro la kuyandikira kwa thupi lililonse lakumwamba loyang’aniridwa.
– Oumuamua adalemba liwiro la makilomita 26 pamphindikati.
– Borisov adayenda makilomita 33 pa sekondi iliyonse.
– 3I/Atlas imaposa zam’mbuyo ndi makilomita 57 pamphindikati.
Kutulutsa ndi kuyambika mumayendedwe a nyenyezi zakutali
Mapangidwe ndi kuthamangitsidwa kotsatira kwa zinthu zakuthambo monga 3I / Atlas zimachitika panthawi yachisokonezo pakusintha kwa mapulaneti akutali. Zitsanzo zakuthambo zimawonetsa kuti kuyanjana kovutirapo kokoka ndi mapulaneti akuluakulu a gasi kapena kuyandikira kwa nyenyezi zina kumatha kukhala ngati ma slingshots achilengedwe, kutulutsa ma comets ndi ma asteroid kuchokera m’njira zawo zoyambirira. Além Kuphatikiza apo, zinthu zoopsa monga kuphulika kwa supernova kumapangitsa mafunde odabwitsa omwe amatha kusesa zida zotumphukira mumlengalenga wakuya.
Zinthu zimenezi zitamasulidwa ku mphamvu yokoka ya nyenyezi zimene makolo awo amaziona, zimayamba ulendo wapaokha umene ungakhale wamuyaya pamlingo wa chilengedwe chonse. Danga pakati pa nyenyezi, ngakhale lalikulu komanso lowoneka ngati lopanda kanthu, lili ndi matupi osawerengeka omwe amangoyendayenda ofanana ndi 3I/Atlas. Kuthekera kwa chimodzi mwazinthu izi kuwoloka njira ya Sistema Solar ndizowerengeka, zomwe zimapangitsa kuzindikira kulikonse kukhala mwayi wosowa wophunzirira mwachindunji zida zopangidwa m’zigawo zina za Via Láctea.
Zotsatira za mphamvu yokoka ya dzuwa panthawi yapafupi kwambiri
Kudutsa kwa comet mkati mwa Sistema Solar kumayambitsa zochitika zakuthupi zomwe zimadziwika kuti mphamvu yokoka kapena slingshot effect. Unyinji waukulu wa Sol umachita pa chinthucho, ukupinda njira yake yoyambira pamakona ena owerengeredwa ndi zowonera.
Ngakhale kuti kuyanjanaku kumakhota njira ya 3I/Atlas, mphamvu yokoka ya dzuwa silingachepetse liwiro la comet kuti lifike pogwira. Mphamvu ya kinetic ya chinthucho imakhalabe yayikulu panthawi yonseyi.
Akatswiri a zakuthambo amagwiritsa ntchito makompyuta apamwamba kuti adziwiretu malo omwe ayandikira kwambiri Sol. Panthawi yovutayi, yomwe imakhala masabata angapo, kusonkhanitsa deta kumafika pachimake.
Pambuyo pakupatuka kwa mphamvu yokoka, comet imapeza njira yatsopano pokhudzana ndi malo a galactic. Zowona zenizeni zenizeni zimatsimikizira kuti kusintha kwa data kwa orbital kumachitika mosalekeza.
Kusanthula kwa Spectroscopic ndi kapangidwe kake ka mlendo
Spectroscopy imagwira ntchito ngati chida chachikulu chovumbulutsira mankhwala a 3I / Atlas popanda kufunikira kwa mishoni zakuthupi. Kuwala kwa dzuŵa kosonyezedwa ndi chikomokere cha comet kumagawika m’mafunde ataling’ono, kumasonyeza masiginecha apadera a maelementi omwe alipo m’kapangidwe kake.
Zotsatira zoyambilira zimaloza ku ma isotopiki omwe amasiyana kwambiri ndi zinthu zomwe zimapezeka mu Sistema Solar comets. Essa chemical divergence reinforces the object’s classification as an authentic interstellar traveler, carrying building blocks from distant worlds.
Poyerekeza ndi mathamangitsidwe a Oumuamua
Kafukufuku wa 3I/Atlas amatengera kwambiri maphunziro omwe aphunziridwa m’ndime ya Oumuamua m’mbuyomu. Pamwambo wa Naquela, mlendo woyamba wa nyenyezi adawonetsa chiwopsezo chosayembekezereka chopanda mphamvu yokoka pomwe amachoka ku Sol.
Kufotokozera kwasayansi kovomerezeka kwa Oumuamua chodabwitsa kumakhudza kutulutsa mpweya wa haidrojeni kapena zinthu zina zosasunthika zomwe zatsekeredwa mkati mwa chinthucho. Kutentha kwadzuwa kumatsitsa zida izi, ndikupanga mphamvu yachilengedwe yofanana ndi injini yaying’ono yoyendetsa.
Ofufuza tsopano akuyang’anira 3I/Atlas pamakhalidwe ofanana a thermodynamic. Kuzindikira kwa ma jets a gasi kapena kupangidwa kwa mchira wodziwika bwino kumapereka chidziwitso champhamvu chamkati mwa matupi opangidwa mu nyenyezi zina.
Kuyang’anitsitsa mosalekeza pogwiritsa ntchito malo owonera pansi ndi mlengalenga
Kupeza mwayi wophunzira 3I/Atlas kumafuna mgwirizano wapadziko lonse pakati pa zida zazikulu zakuthambo zapadziko lapansi ndi zowonera zakuthambo zozungulira. Observatórios yomwe ili pa Chile, Havaí ndi Ilhas Canárias amawongolera zida zawo mogwirizana kuti agwire mitundu yosiyanasiyana ya kuwala komwe kumatulutsa kapena kuwonetseredwa ndi comet. Kuphatikizika kwa ma telesikopuwa kumathandizira kuyang’anira mosadukiza, kubwezera kasinthasintha kwa Terra ndi kusiyanasiyana kwa nyengo. Zomwe zasonkhanitsidwa nthawi yomweyo zimakonzedwa ndi ma supercomputer, omwe amasefa phokoso lakumbuyo ndikulekanitsa chizindikiro ku chinthu chapakati. Essa gulu lasayansi lapadziko lonse lapansi silimangopanga mapu amakono ndi kulondola kwa millimeter, komanso kusungitsa ma terabytes a chidziwitso cha photometric ndi nyenyezi zomwe zidzapangitse kafukufuku wamaphunziro kwazaka zambiri zikubwerazi, pakapita nthawi comet itasowa mumdima wakunja.
Ulendo womaliza wopita ku danga lakuya
Kumapeto kwa gawo lalikulu lofikira, 3I / Atlas imayamba ulendo wake wotsimikizika kuchokera ku heliosphere. Kuthamanga kosalekeza kumatsimikizira kuti chinthucho chidzapitirizabe kuyenda modutsa pakati pa nyenyezi, popanda kubwerera kudera lathu la mlalang’amba.
Kusiyana kwakukulu pakati pa nyenyezi zam’deralo ndi interstellar comets
Kusiyana kwakukulu pakati pa Sistema Solar comets ndi alendo akunja kwagona pakusungidwa kwa mawonekedwe awo oyambirira. Enquanto matupi am’deralo adakhudzidwa kwambiri ndi cheza chadzuwa pakapita nthawi, zinthu zapakati pa nyenyezi zidakhala zitaundana mu ziro zero zakuya.
Kusungirako kutenthaku kumasintha 3I/Atlas kukhala kapisozi wanthawi yake. Kuphunzira pamwamba pake ndi mpweya wotuluka kumapatsa asayansi malingaliro achindunji amikhalidwe yamankhwala omwe amapezeka mu protoplanetary disk ya dongosolo la nyenyezi losiyana kotheratu ndi lathu.
