Chii kure kusvikira nyeredzi mugadziriro Alpha Centauri? Zvinoita here nendege Alpha Centauri?

Alpha Centauri - chinangwa kubhururuka musere musere mumabasa zhinji kungova Genre kuti renyaya. Icho nyeredzi pedyo rinoreva nhamba kudenga, embodying kunozivikanwa centaur Chiron, maererano mungano yechiGiriki, aichimbova mudzidzisi Hercules uye achilles.

Nyanzvi Modern, uyewo vanyori, nguva dzose kuuya shure mupfungwa kune nyeredzi hurongwa, nekuti hazvina chete aikwikwidza wokutanga refu nzvimbo basa, asiwo zvinoita muridzi vepasi.

mamiriro

Alpha Centauri nyeredzi hurongwa inoumbwa matatu nzvimbo zvinhu: Nyeredzi maviri chete zita uye zviratidzo A uye B, uyewo Proxima Centauri. Nokuti nyeredzi idzi kunoratidzwa ne napedyo maviri zvinoriumba uye kure - wechitatu. Proxima anongova ichangoburwa. Distance kuna Alpha Centauri zvose zvinhu zvayo anenge 4.3 chiedza-makore. Stars pedyo Earth panguva ino. Panguva iyo uchitsanya kubhururuka Proxima: isu tose mugove 4.22 chiedza makore.

yokutenderera zuva hama

Alpha Centauri A uye B zvakasiyana shamwari kwete chete daro paNyika. Vari akasiyana Proxima nenzira dzakawanda rakafanana zuva. Alpha Centaur A kana Rigel Kentavrus (rinoreva "gumbo Centaur") chichiwedzera chikamu peya. Toliman Uye sei rinonziwo nyeredzi - yeyero zvipfupi. Kubva Panyika nayo zvakakwana yakajeka, sezvo ane razero zvikuru. Ipfungwa Izvi zvinoita chechina pandandanda kupfuura unoshamisa pfungwa denga usiku. chinhu saizi kushanda zvinonyatsobatana uyewo zuva.

Star Alpha Centaur In yedu muduku chinovheneka uremu (anenge 0,9 nguva kukosha runoenzanirana parameter kwezuva). Rinoreva zvinhu wokutanga unokosha, uye padanho luminosity anenge maviri nguva shoma pane kuti huru chenyeredzi redu renyeredzi chimedu. Daro pakati maviri pedyo shamwari iri 23 muchadenga dzakabatana, kureva, vari riri 23 nguva kure kubva mumwe kupfuura Nyika inobva kuzuva. Toliman Toliman A uye B pamwe dzitendererane muzinda vakawanda ane makore 80.

Kuwanikwa

Masayendisiti, sezvo kare akataura, vakaisa dzaitarisira pamusoro kuwanikwa upenyu pedyo nyeredzi Alpha Centauri. Mapuraneti ineshongedzo kuti huvepo pano anogona kufanana Pasi zvakafanana sezvo zvakamisa hurongwa pachavo vari nowenyika yedu nyeredzi hurongwa. Zvisinei, kusvikira nguva pfupi yapfuura, mitumbi izvi yepasi pose yakawanikwa pedyo nyeredzi. Distance haagoni zvakananga kuchengeta mapuraneti. Kuwana uchapupu nezvokuvapo Earth chinenge kwaingova zvinogoneka tendero unyanzvi kuvandudzika.

Nokushandisa TOUR-velocity nzira, masayendisiti vaikwanisa kuziva nokufamba chaizvo duku Toliman, yomuka pasi pokudzora rinokweva ehondo mapuraneti orbiting nayo. Saka rwaiwanikwa zvinoratidza kuvapo dzinenge imwe chinhu chakadaro munyika. The vibrations anokonzerwa nyika richiratidzwa muchimiro chacho misha yose masendimita 51 pasekondi yoga yoga mberi uye ipapo shure. In pano ezvinhu akafanana kufamba kunyange kupfuura muviri yaizova oneka chaizvo. Zvisinei, pane chinhambwe 4.3 chiedza-makore kuwanikwa oscillations zvinoita sezvisingabviri. Zvisinei, rakachengetedzwa vakanyorwa.

hanzvadzi Wepasi

Akawana nyika orbiting Alpha Centauri B mumazuva 3.2. Riri pedyo chaizvo kune nyeredzi muchadenga nharaunda iri kagumi kudarika runoenzanirana parameter hunhu Mercury. The vakawanda ichi nzvimbo chinhu pedyo pasi uye anenge 1,1 kurema Blue nyika. In fanano ichi inoguma: napedyo, maererano masayendisiti, zvichireva kuti matangiro akaita upenyu pasi redu hazviiti. The simba chiedza kusvika kwaro pamusoro rinopisa kumusoro yakawandisa naye.

The pedyo

Rokuti wechitatu nyeredzi ezvinhu, zvichiita zvose yakakurumbira renyeredzi - Alpha Centauri C, kana Proxima Centauri. Rokunze muviri The zita rinoreva "pakarepo". Proxima kunodyira kubva neshamwari dzavo pane chinhambwe 13.000 chiedza makore. Ichi chinhu regumi nokukura, tsvuku zvipfupi diki (anenge ka7 duku pane zuva) uye fishy chaizvo. Ona pamwe akashama ziso hazvibviri. Nokuti Proxima mamirire "kudzikama" hurumende: Nyeredzi anokwanisa maminitsi mashoma kuti achinje kukosha kwayo kubwinya kaviri. Chikonzero "maitiro" ichi munyika dzakawanda pezvakaitwa kuitika richienda zvipfupi.

Dual nzvimbo

Proxima yagara kuonekwa chinhu Arifa Centauri gadziriro wechitatu, orbiting ari peya A uye B kwemakore anenge 500 nemakore. Zvisinei, munguva pfupi yapfuura, nyika maonero ari kuwedzera kuti dzvuku zvipfupi haana ukama navo, uye kukurukurirana zviri zvitatu zvomuchadenga - kwekanguva chinoshamisa.

Chikonzero mubvunzo rava mashoko anoti kuti peya nyeredzi yakanyatsobatana haana zvakakwana simba regiravhiti kukwezvana, nokuchengeta achiri uye Proxima. Vakagamuchira pakutanga pakati 90s wekupedzisira remakore kwenguva refu nguva mashoko anoda mamwe chisimbiso. Recent zvaanorumbidza uye Masvomhu masayendisiti mhinduro unequivocal haana kupiwa. Maererano zvekungofungira, Proxima vanongogona kuva chikamu hurongwa katatu uye kufamba famba vakawanda muzinda regiravhiti. Uyezve, ayo muchadenga anofanira sokuti elongated denderedzwa, uye pfungwa yacho iri kure kwazvo kubva pakati - mumwe nenyeredzi vakarinda mairi iye zvino.

zvirongwa

Chero zvakanga, kureva Proxima purogiramu dzibhururuke pakutanga, kana zvava kuwanikwa. Rwendo Alpha Centauri panguva ino nenhanho kukura muchadenga michina anogona kwemakore anopfuura 1000. Nguva iyi kungoti zvisinganzwisiswi, nekuti masayendisiti vari kushingaira mubasa kutsvaka nzira kuderedza nayo.

Boka NASA vatsvakurudzi inotungamirirwa Harold White ari kutanga basa "Speed", nemhaka iyo inofanira kuva injini itsva. Its chinokosha chichava kugona kukunda kumhanya chiedza, zvichiita kutiza kubva Earth kusvika pedyo nyeredzi vachava vhiki mbiri chete. chishamiso kwakadaro ruzivo ichava Nyanzvi chaicho cohesive basa yokungotaura yefizikisi uye experimenters. Saka kure, zvisinei, ngarava, nokukurira kumhanya chiedza - mune ramangwana. Zvinofungidzirwa Marc Millis, kamwe vaishanda NASA kuti, kufanana zvemichina, chero bedzi huripo panguva pamwero aripo mberi kufamba, kuva zvechokwadi kwete kwokutanga pane muna mazana maviri nemakore. Rutapudzo rokuti runobvira chete kana pakuvhurwa zvichaitwa kuti zvinoshamisa anogona kushandura huripo pfungwa pamusoro kufamba muchadenga.

Zvino Proxima Centauri neshamwari dzayo kuramba chinangwa chinzvimbo, asingawaniki munguva yemberi iri pedyo. Technology, zvisinei, kunoramba kuri nani, uye mashoko matsva pamusoro zvinoitwa zuva nenyika dzinotenderera pariri - kuti kutarisana uchapupu. Kunyange nhasi, masayendisiti zvinhu zvakawanda, anenge 40-50 apfuura uye havana kurota.
