A hoku nenoai nei?

Hoku o nā'ēheu kēia'ēheu o nā pono ai, a pau keia ano o ka hoku i nui ... Akā, ua ole a pau o na hoku i loko o ka lani, i ka ia? Oddly lawa,ʻaʻohe. Star nenoai i he okoa 'ole, a he okoa Mea Maluna o kona eiiiiiaiou. A i ka pūwāʻana i loko o ka 'ē aʻe'ōnaehana hiki e oi ma mua o kekahi. Ua mea ma luna o kēia kumu i loko o ka wahi mua, a me ka hanohanoʻepekema o ka Wiliau Hōkū stellar nenoai.

Ma mua o na lede 'ana i ka Mea Maluna, ia mea pono e möakäka hou i loko o mau ana au i ke. Penei, ka hoku nenoaia - he galactic huahelu haku o ka hoku revolving ma luna o ka hoʻokumu 'ia alanui, a ua hoʻopili gravitationally. Eia hou, ma laila i koe i ka planetary'ōnaehana, iloko olaila, ma ka huli, asteroids a me ka Honua ma ka. No ka laʻana, he ahuwale laʻana o ka hoku'ōnaehana - nieia, maʻa iā mākou.

Eia naʻe, ua piha i ka mea a pau Wiliau Hōkū a me ia 'oihana. Star nenoai OAOOUIEeE kuhikuhi ma ka multiplicity. Ua Ua maopopo i keia nui ka loa i kaupalena 'ia, mai ka lōʻihi manawa'ōnaehana me ekolu a oi hoku o ka like cia hiki ole nei. Kumupaʻa hiki e ua hoʻohiki wale ma ka luna kiʻekiʻe. Oia i ke kolu o ke keʻena nei i kekahi hoku i "waho o ka puka",ʻaʻole ia e hele kokoke i ka hale hānai pālua'ōnaehanaʻana ma mua o 8-10 Radii. Ia mea,ʻaʻole e pono no ka mea, e ia he hookahi - keia e pono e ka papalua hoku. Nohona ma, 100 hoku puni kanakolu - hookahi, he kanaha-ehiku - kaulua, he iwakalua-ekolu - pa.

mau hoku

Like ka huihui, na hoku, he mau hale o interconnected ae gravitational maluhia iho la, i ka mea ia manawa he pōkole kaawale mai kekahi i kekahi. Ka mea, e neʻe pu, kaʻapuni a puni ka piko o ka umekaumaha o ko lākou nenoaiu - ai-kapa barycenter.

A Kuhina Nui laʻana o Mizar, ike ia iā mākou ma ka Big Dipper. He waiwai ka uku noonoo ana i kona "i lawelawe," - kona awelika hoku. Eia oe, e hai i ka pōwehiwehi glow o kona paʻa. Mizar-Alcor - aeaie hoku, he mea hiki i ka ike ole kūikawā hana. Inā 'oe ke hoʻohana i ka telescope, ka mea i ike ia ia Mitsar- o ka palua ana, oia hoi o eiiiiiaiou A a me B.

aeaie hoku

Star nenoai ma i nā kukui hōʻikeʻia, i kapaʻia papalua. Oia ka'ōnaehana makemake e ku paa auanei ina he mea ole kai ole, hoolilo o ka nuipa o ka hoku, a me ka haunaele ana o nā koa. Ka malamalama a neʻe loa ma ka elliptical ka Astronomical kokoke endlessly revolving puni kona konu o ka nuipa o ke kahua.

Ke kākoʻo kaulua hoku

ʻO kēlā mau māhoe hoku e e ike hiki me ka telescope, a hiki i ole mea i kapa pilikia makapō binaries. Alpha Centauri, no ka laʻana, mea ia he kahua. Starry lani koloka ia examples. Ke kolu o ka hoku o keia'ōnaehana - ke kokoke o ko nā mea a pau i ko kakou mau - Proxima Centauri. Loa pinepine, e like me ka mau ana o halves oko ma ka waihoʻoluʻu. No laila, Antares mai he ulaula a me ka uliuli hoku Albireo - uliuli a me ka alani, Hoʻokolohua Cygni - melemele a me ka uliuli. A pau o kēia mau mea i oluolu i ka mālama i loko o ka refracting telescope e leie aku 'Oihana e, he hoÿomaulia i na wahi o na hoku, kā lākou māmā a me ka ao ao.

Spectroscopic binaries

Pinepine ka mea, huli mai i kekahi hoku i kekahi hoku'ōnaehana ke aupuni 'oi aku a kokoke i ka mea' ē aʻe. Pela ka nui o lakou i hiki ai ka loa ikaika loa telescope mea,ʻaʻole hiki ke hopu lākou duality. Ma keia hihia, ke kokua mai spectrometer. I ka maalo ae la oia ma ka mea malamalama ua decomposed i loko o ka pae delimited ma kaʻeleʻele laina. Mau auka e paa ai i 'oni iki e holo mai a wehe i ka luminary mai kekahi kilo. A hiki i ke anoe o ka pae o ka aeaie hoku mākou i laina elua, aeʻalo ana i ka noi o nā eiiiiiaiou puni kekahi i kekahi. No laila, Mizar A a me B, Alcor - spectroscopic aeaie. I ka Ia manawa ka mea, e hoi noniakahi i loko o ka nui nenoaiu o eono hoku. Just visually kaulua eiiiiiaiou o Diosekouro ka - he hoku i loko o ka huihui Gemini - mea he spectroscopic aeaie.

Noticeably binaries

Aia nō i loko o ka Wiliau Hōkū a me ka 'ē aʻe hoku nenoai. No ka laʻana, ua eiiiiiaiou a i hoʻoneʻe ai i ka pelane o ko lākou mau orbits kokoke i ka laina i ke kiloʻana o ka maka, mai ka honua aku. Kēia 'o ia hoʻi i ka mea, a pōhina i kekahi i kekahi, e pili ana i ka ae Pu. Iloko o kela mea keia mea o lakou, ua hiki ke ike wale i kekahi o na kino, ma laila hoemi lākou nohona ma brilliance. I ka hanana i kekahi o na hoku o ka oi aku keia ka ho'ēmiʻana mea nui.

Kekahi o ka loa kaulana markedly binaries - Algol i loko o ka huihui Perseus. Me ka kūlike loaʻanuʻu o 69 hora, kona'ālohilohi Hawaiʻi i ke kolu o ka waiwai, akā, ma hope o 7 hola maoli he hou i ka lua. Keia hoku Ua pinepine kapaia "lewa ae ke diabolo." Ike aku la oia ua nō ia ma 1782 ma Pelekāne John Goodricke.

Me ka nui o ko mākou Honua aeaie hoku nana e like me ka ee iaaanu aey, a ma hope o ka kekahi manawa wā mawaena EUIAaIN ka olinolino, i coincides me ka wā o ka hoku a puni kekahi i kekahi. i kapaia na hoku nō markedly ee iaaanu aey. Kaawale mai kēia mau mea, ma laila nō ka physical aiaiiuo o ko ke ao nei - tsifeidy, i ka olinolino o ka i hooponopono ia e na keʻano o ka hanaʻana.

Ke evolution o aeaie hoku

Loa pinepine, kekahi o na hoku o ka aeaie'ōnaehana mea nui, hoʻomaka koke maalo ae la oia i kona haawiia ke ola kalapona. Oiai ka lua o ka hoku mea maʻamau, kona "hapalua" huli i loko o ka ula nunui, laila, he keʻokeʻo dwarf. Ka loa hoʻi i hoihoi mea i loko o kēia'ōnaehana hoʻomaka ka wā o kaʻulaʻula dwarf hoku i ka lua. White ma keia kulana,ʻo hoʻonui kinoea hoʻonui "hoahanau." About 100 tausani makahiki, ua lawa ia no ka mahana a me ka puʻe hiki i kaʻilikai koi 'ia no ka nukelea kuʻi nukeliu. Kinoea iwi explodes hoomalamalama mai me ka hiki ole ikaika, e kauoha ana i ka dwarf luminosity, piʻi pū aneane he miliona manawa. Kilo kamaʻilio ma ka Honua i kapa aku ai ia i ka hanau ana o ka hou hoku.

Astronomers huai ae ka hana a ia i kekahi kahua ma kekahi o na eiiiiiaiou mea he maʻamau hoku, a me ka lua o ka - he loa nunui, akā,ʻike makaʻole, me ka henua pololei kahi o, pili X-Ray pāhawewe. Ua paipai i ka lua o ke keʻena o kaʻeleʻele puka - na koena o ka manawa hookahi papakaukau hoku. Eia, e like me ka poe akamai, i ka penei i wahi: ka hoʻohana 'ana i ka ikaika umekaumaha, ʻeleʻele puka ,ʻo hoku kinoea. Ua unuhiʻia i loko o kaʻoni iho ma kiʻekiʻe wikiwiki nui, ka mea i pii kai iki ana, ka hoʻokuʻu 'mua nalowaleʻana aku i loko o ka puka i ka ikehu i loko o ka palapala o ka X-kukuna.

ʻepekema, ua manao ia o ka ikaika X-Ray kumu proves ke ola ana o kaʻeleʻele puka.

Triple hoku'ōnaehana

Poe hoku nenoaiu, i hiki ke ike, mea ole ka mea wale koho 'ole. Ma waho aʻeo i hookahi, a papalua hoku i loko o ka'ōnaehana hiki e ua hoʻonānā a me ka nui o ia mau mea. Keʻano o ia mau nenoai Ua nui oi luna 'ma mua o ka waʻa. Eia naʻe, i kekahi manawa, loaʻa nō hōkū nenoai me ka uuku nui o ka malamalama (i loko o oi, nae, nā huahelu), a loaʻa he 'ano meaʻano. E kāhea aku iā ia i kekahi mau kahua. Inā na hoku i loko o ka'ōnaehana, ekolu, ka mea, i ka Triple inoa.

Ka loa, he pono ole i ke ano o ka mau nenoai - Triple. No laila, hoʻi i loko o ka makahiki 1999 ma ke Kahua o mau hoku o ka 728 mau nenoai, oi aku 550 i Triple. Ma ka malama ana a me ka loina o ka luna kiʻekiʻe o ka haku mele 'ana o kēia mau nenoai mea i na hoku elua i pili loa kaulike, hoʻokahi loa ke kaawale ana.

I kumumanaʻo kükohu mau hoku nenoai ua ikaika nui ae huikau ma mua o papalua, no ka mea, o ka'ōnaehana hiki hōʻike chaotic kolohe. He nui o kēia mau paʻi hua e, ma ka mea, he nui ka poe, kūpono ma ka ejection o kekahi o na hoku. Pale ia i ka ha i ka hiki wale i ka poe nenoai, ma i na hoku i hoonohonoho ia ma ka hierarchical ano. Ma na hihia a pau i nā eiiiiiaiou e māheleʻia i loko o nā pūʻulu o kaʻapuni a puni ka piko o ka nuipa a nui ka Astronomical. Loko o nā pūʻulu like pono ia e ka maopopo luna kiʻekiʻe.

kiekie multiplicities

KU¯ ikeia hoku nenoai, a me na mea he nui eiiiiiaiou. No laila, Scorpio ua haku o ka oi mamua o na hoku ehiku.

No laila, e huli mai i ole wale i ka Honua i ka hoku'ōnaehana, akā, na nenoai ia lakou iho i loko o ka Wiliau Hōkū e ole ka ia. Kēlā me kēia no ia mea kū hoʻokahi, okoa a me ka loa hana hoihoi. ʻepekema, e wehe aʻe hou a nui i ka helu o ka hoku, a malia paha koke mākou eʻike e pili ana i ke ola ana o ke akamai ola,ʻaʻole wale nō ma luna o mākou iho Honua.
