White dwarf, eleele dwarf

Ma kilohōkū, he nui na undiscovered, pohihihi, a me kekahi manawa wale kupaianahaʻike manaʻo, kekahi o i mea he keʻokeʻo dwarf. Mawaena o ka mea mua, e noiʻi i kēia mau lani mea e hoʻoikaika i nä känaka 'epekema Wilhelm Bessel. la oia loaʻa iā lākou muli o kona kulana ma ka ulia. Eia ke ano o kona palapala noiʻi i ka brightest hōkū - Sirius. Ukupanee ma ke aʻoʻia e hoohana i kena ae la i ka hana ala o ka Honua, o ka mea ia ia ua undulating. Bessel ka hoʻomaka 'ana e kakali ana no paha kumu i hiki ke alakai i na malihini, i kona ike aku, i kaʻike manaʻo.

A eia i ka mālamaʻana o Sirius ua paipaiʻia kānakaʻepekema i ka manaʻo i loko o ka wahi koke o ko ke ao nei o kekahi, i ike ole, he hoku i mea ole i nanaia, akā, kona gravitational keiki i ka ikaika. Kēia keʻae i ka 'ike o periodical fluctuations i loko o ka neʻeʻana o Sirius. Kekahi Kaka Ua i e ka astronomer. He? Aaeaaaaony i ina ka keʻokeʻo dwarf mea oiaio, alaila, i ka wā o ka lapaau a me Sirius, a me ka ike ole Honua a puni lākou, he pono ole mawaena konu o ka umekaumaha ke kaha like kokekau i ka 50 makahiki. Ka Sirius nō,ʻo kānakaʻepekema, mai nā mea a pau ma luna o ka honua a me kona mau mea pohihihi a me ka waiho ana no he imi-ma hope o mea o ka noiʻi.

Inā 'oe wale wehewehe i ke keʻokeʻo dwarf, ia mea he mea o ka pohihihi ano o i ua maluhia i hūnāʻia aku i loko o keʻena kihi o ka ke ao holoʻokoʻa a me ka mea i ke koena o ka hoku. I nā lā kahiko, i ka wa a ka'ōnohi lako a pan, aole ia i keia manawa i na mea kiekie, ka hoʻonā 'uea, ka mea i manaoio aku i ke keʻokeʻo dwarf hōkū - he ke nānā hanana, akā,ʻepekema i aku nei au i ke ku pono ana i keia la. E like me ke 'Amelika astronomers, i ka helu o kēia mau ē aʻei kūpono aku i 10 ieeeea?. O ka 5% o ka helu o ka hoku i supposedly i loko o mākou Wiliau Hōkū.

ʻepekema,ʻo ke dwarf hoku - i kēia mau mea kā mākou hea ka hoalauna. White dwarf mai ka lewa kona mānoanoa ua mau haneri o mika, ka mea, ua haku no na mea he nui Nine Inchʻikeʻia e ke kanaka. No kekahi laʻana: kalipuna, ka hao, hydrogen, titanium'okesaside, helium, a me ka kalapona. Kona anawaena mea ikaika, a me ka ewaewa ole i ka 40 000 ei. Elua ano o keʻokeʻo dwarfs: wela a me ke anu, me ka lewa i komo loa o ka helium. E like me kekahi hapa o ka mea mua hydrogen lakoʻepekema ike ia 0,05%.

Dwarf Honua hele e like lalana ana ia ia ma ka cannonball, a hoʻololi wela ana houʻia ka ikehu. Ka nui like 'ole o kēia mau ano lani kahi mea mau i ka ia. Astronomers pōpilikia waiwai, ua oi aku ma mua o kā lākou ke kaupaonaʻana, no ka uuku lākou ke kahahńnai o.

Ke keʻokeʻo dwarf He hoʻokahi wale ke ano o ka ikehu - wela. Kona anuanu maila 'hiki ke hoohalikeia me ke anuanu maila' o ka metala kookoo, a ua laweʻia mai o ka fryer. Mua, ke kaʻina hele koke, akā, i ka wā i ka wela i loko o hina, ka huʻihuʻiʻana i lohi.

ʻepekema manaʻo no ka wā o kekahi mau haneri miliona makahiki o ka keʻokeʻo dwarf luminosity haule ma ka wale 1% o ka huina luminosity o ka la. Ma ieeeea? O nā makahiki o ka mea i hana i kaʻeleʻele dwarf. He mau kino i ua uuku? Anoee ai mamao, akā, i ka nui a me ka hoihoi i mau i loko o ka mahinaʻai o ka Hawaii o kānakaʻepekema.

An hana hoihoi 'mamuli o ke kanaka o ke kaupaonaʻana i ka ho omaulia e lawe i ka mooolelo o ka umekaumaha ma luna o ka ili o ka keʻokeʻo dwarf. Ina he kanaka i ke kaumaha o 75 kg ma ka Honua, ka wā o ka Sun, e ia i ke kaumaha o ka 2 tona, e hoonui ana ia i ka dwarf Honua i 120-140 tona.

A nui hoku ke ao holoʻokoʻa haalele i ka ikehu no miliona o ka makahiki, a me ka mea dwarfs hoola a aeo ka thermonuclear makahiki, na luna o ieeeea? O nā makahiki. Mea pohihihi e noho me ka nui loa ma luna ma mua o ka pahaʻaoʻao o ko lākou kākoʻo pāʻoihana, akā, ka mea, ua manaolana i koke ai ka paku o ka pohihihi, e wehe. Ma kekahi, i loko o nā makahikiʻeleu hana ua lawe mai ma astronomers, mai ke kula nui. Washington.
