kunzwisisa uye kudzidza Chii chinonzi lenticular galaxies?, zvinokosha kuti tinyatsoziva kuti boka renyeredzi chii. Magalaxi iboka renyeredzi, zvinhu zvemuchadenga, makore, huruva, gasi, zvinhu zvakasviba uye mitumbi yemuchadenga inoroyiwa kunucleus nekuita kwesimba rinokwevera zvinhu riripo uye rinogona kuumba dhayamita yemamiriyoni emakore echiedza, uye pa. nguva yavo, yakabata kunyange mabhiriyoni emitumbi yomuchadenga mukutenderera kwayo. 
Chii chinonzi lenticular galaxies
Mupfungwa iyi, lenticular galaxy imhando yeintermediate galaxy, kureva kuti, inowanikwa pakati pe girazi elliptical uye spiral galaxy iyo maererano neHubble Sequence yakanyorwa seS0. Kana iwe uchida kupinda zvakadzika muchikamu chezvakasiyana mhando dzemakwara enzou, nyaya ino inogona kubatsira zvikuru.
Saizvozvo, lenticular galaxies ane dhisiki inomiririra, (kunge spiral galaxies) yakaneta kana kurasikirwa yakawanda kana yese yenzvimbo yavo (senge elliptical galaxies), uye nekudaro kushaya maoko ekutenderera, zvisinei Dzimwe nguva kune imwe nhamba yechinhu chekudenga, pamusoro peguruva rose. Vanoumba 3% chete yemapoka enyeredzi ari mu zvose.
Kurongeka kwemagalaxi e lenticular
Kuti tizive zvishoma tinogona kutaura kuti nyeredzi lenticular Ivo vanoverengerwa seinotevera:
SO
Chikoro cheS0 chakatanga kutsanangurwa naEdwin Powell Hubble muna 1936 sechimiro chepakati pakati pe elliptical uye spiral galaxies; Gerard de Vaucouleurs vakazochenura iyi nhevedzano uye vanoiswa mairi se: S0 (hapana bhawa yepakati), SAB0 (pakati bar rudiment), uye SB0 (ine yepakati bar). Panguva imwecheteyo, pane zvakare kutaura nezve: E/S0 (elliptical galaxies inorangarira a lenticular).
SW-
Nezvezviri pamusoro apa, S0- (lenticular galaxies yakanyanya kufanana neelliptical), S00 (lenticular galaxies ane kumwe kugoverwa kwemukati), uye S0+ (huruva iripo uye mune dzimwe nguva inobatana nemakwara enzou) inoonekawo. Midzimu -mixed symbolization S0/a-); Zvikamu zviviri izvi - sekuvepo kana kusavapo kwebhawa repakati uye kuti zvinoonekwa kana kusaonekwa - zvinowirirana, sezvinoita izvo zvinoratidza kuti mune zvindori here kana kuti kwete. Pane rumwe ruzivo nezve galaxy classification izvo zvingave zvichifadza.
Mucherechedzo mutsva wakanaka wekupatsanura wakakwaniswa nenyanzvi dzemuchadenga John Kormendy naRalf Bender imwe yakada kufanana neiyo inoshandiswa kune spiral galaxies zvichienderana nehuwandu hwepakati pebundu rawo uye inofambirana nekutevedzana kwemapoka enyeredzi anotenderera; saka, isu tine magalaxies S0a-S0b-S0c (ane epakati akatevedzana S0ab uye S0bc), akafanana categorizations Sa, Sab, Sb, Sbc, uye Sc for spiral galaxies uye ayo anobatana ne dwarf spheroidal galaxies; Iyi sisitimu zvakare inosiyanisa pakati pemagalaxi e lenticular ane kana asina mbariro.
Kana tangoziva kuti lenticular galaxies chii, tasvika zvino kwaanobva. Ichi ndicho chikonzero tine kuti marudzi aya emagalaxi anowanzo kuve akawandisa mumapoka enyeredzi akapfuma, mukubira makwara enzou, uye zviri pachena kuti vaimbove magirasi enzou anodurura gasi rawo nekukukurwa nemhepo inopisa ye intergalactic inozadza nzvimbo ye intergalactic uye/kana nekudyidzana kwegiravhiti nemamwe ma<em>nebula; mbiri dzepakati dzinomiririra (zvichida chinhu chimwe chete) pakati pechimwe nechimwe chiri makwara enzou enzou, ane zvinhu zvishoma zvemuchadenga uye kuumbwa kwenyeredzi pane imwe nyeredzi yakafanana, uye makwara enzou anoshivirira, ane sangano rinotenderera asi kurongeka kwenyeredzi kuduku kana kuti kusina .
Imwe pfungwa yakaitwa nenzira imwecheteyo, pahwaro hwekunyepedzera kwemasvomhu, ndeyekuti magalaxi enzou ndiwo mhedzisiro yekubatanidzwa pakati pemaviri. mapoka enyeredzi mapropeller ehuwandu husina kuenzana uye akapfuma mumhepo. Ukuwo, makwara enzou angave akachinja kuva rudzi irworwo rwenyeredzi nokudya zvinhu zvawo zviri pakati penyeredzi.
Zvisinei, maererano nekuongorora kwakasiyana-siyana kwave kuchiitika kwemakore akawanda kusvika zvino, zvaibvira kuziva mapoka enyeredzi lenticular zvazvino zvinogona kunge zvakamuka kubva kuma spiral galaxies, kwakabva zvinhu izvi, kunyanya izvo zvakakura, zvinoramba zviri dambudziko rakavhurika. Kana uchida kudzidza zvakawanda nezve magadzirirwo enyeredzi, unogona kushanyira chinyorwa ichi: kuti mapoka enyeredzi anoumbwa sei.
Sezvineiwo, semuenzaniso, zvakaratidzwawo kuti mazhinji enzou dzenzou angave akaita sezvaari nhasi kubva pakuvambwa kwawo, achicherekedza nguva nenguva stellar alignment buds, pane spiral galaxies akashatisa nharaunda yawo. celeste.
Hunhu hwe lenticular galaxies
Sezvatotaurwa pamusoro apa, isu tatoziva kuti chii chinonzi lenticular galaxies, zvisinei, tinofanira kuziva chaizvo kuti vanomiririrwa sei, kureva kuti vakaita sei.
Core
Iyo lenticular galaxies ine yakanyanyisa gobvu uye yakakura nucleus, ine yakazara flat disc yakaitenderedza, iyo isina spirals, izvi imhaka yekuti maitiro akadurura yakawanda kwazvo gasi uye. powder saka hapana kutsanangurwa kukuru kwenyeredzi.
Nyeredzi
Nyeredzi dzinowanikwa mukirasi iyi yemapoka enyeredzi dzinopfuura nekusakwana musimbi, ndiko kuti, zvimisikidzo zvakanyanya kubhadhariswa kuHelium, izvo zvinoratidzwa Population II nyeredzi, maererano nechikamu cheWalter Blaade. Lenticular galaxies haina huwandu hukuru hwesatellite galaxies kana masumbu mukati mavo, zvisinei kuchine huwandu hwakakura hweguruva uye makore spatial. Kuti udzidze zvakawanda nezve maitiro emapoka enyeredzi kazhinji, tinokurudzira iyi link: maitiro emapoka enyeredzi.
Nzvimbo
Aya marudzi emakwara enzou anowanzo kuwanikwa kunyanya mumirwi yenyeredzi yakapfuma muungano idzi, mumakore uye. miviri yenyeredzi, zvisinei, nenzira imwechete vanogona kuwanikwa munzvimbo dziri dzoga uye dzakasurukirwa, dzakakomberedzwa nekushayikwa kwemuviri wakasviba.
Lenticular galaxies in the Universe
Saizvozvowo, kunyange zvazvo lenticular galaxies isingabatanidzi mari yakawanda mukati me Universe, kana mamwe akasarudzika ane echokwadi anoshamisa typologies awanikwa, saka ndiri kutaura nezve Centaurus A uye NGC 2787. Kana iwe uchida kuverenga zvakawanda nezve Centaurus A galaxy, unogona kubvunza. ichi chinyorwa.
Centaurus A
Iri girazi renzou riri kupfuura nzvimbo yeCentaurus, nekuona kubva kupasi Pasi, mairi unogona kuwana nyeredzi huru dzakatsvuka, dzinoratidza kuti dzakagadzirwa uye kuti dzakararama mamiriyoni emakore, iri kuchamhembe kweMilky Way uye inongoonekwa kubva kumaodzanyemba kwenyika yedu uye inowanikwa. anenge mamiriyoni 14 emakore ake.
Iri gomba renyeredzi rine chitarisiko chakasiyana, sezvo kunofungidzirwa kuti dhisiki raro rine huruva imhaka yekuti rakabatana nerimwe nyeredzi mumakore mamiriyoni gumi ekutanga. Chimwe chinhu chinonakidza ndechekuti, kunze kwekunge iri yechishanu inopenya kupfuura nyeredzi mune denga, igwara renyeredzi renzou richiri kuratidza kuchinjika kuputika kwekurongeka kwenyeredzi, nekuda kweiyo supernovae ichangobva kubuda. Kuti uwane rumwe ruzivo nezve chiitiko ichi, shanya supernova inoitika sei.
NGC 2787
Gwara renzou iri rinowanikwa mamirioni makumi maviri nemana echiedza chemakore kubva pasolar system yedu, uye rakanyanya hunyanzvi hwekuve galaxy ine lenticular yakakomberedzwa nenzvimbo dzemhute yakasviba mudhisiki raro, pedyo neaxis, nekuda kwehuwandu husina kukwana nyeredzi chii chakashata nazvo.
Pakupedzisira, tine kuti iwo magalaxies e lenticular, asi nenzira imwechete tinofanira kufunga kuti munyaya ye NGC 2787, iyo inotenderera nekukurumidza, saka inotendwa kuti ine supermassive dema gomba mukati meaxis yayo, zvisinei hazvina kukwanisa kuisimbisa.
