Ciklichnost' galaktik.
Chem galaktiki otlichayutsya drug ot druga.
Kak proishodit-
formirovanie vstrecha s drugimi galaktikami nabor
kriticheskoi massy samo-nagrev razbros formirovanie i t.d.
Esli posmotret' na fotografii - to oni sobstvenno osobo drug ot druga ne ochen'
otlichayutsya, no na samom dele otlichii dostatochno chtoby zametit' ciklichnost' v zhizni galaktik.
Chto opredelyaet dvizhenie v galaktike, dvizhenie v galaktike
opredelyaet srednyaya temperatura prostranstva v galaktike, i nekotorye nyuansy po plotnosti materii v galaktike. Efir kak vozduh v turbine pylesosa nahodyas'
v galaktike s raznoi plotnost'yu pri vozdeistvii na nego centrobezhnogo vozdeistviya priobretaet raznuyu plotnost'. V centre galaktiki ego plotnost' men'she, a
po krayam bol'she.
No est' odno bol'shoe no - chto sobstvenno proishodit v zhizni galaktiki - ona mozhet byt' v shesti temperaturnyh sostoyaniyah, 1 ustoichivo
holodnaya, 2 nagrevayushayasya, 3 sbalansirovannaya, 4 peregrevayushayasya, 5 ustoichivo goryachaya 6 ostyvayushaya
Vot na odinakovom rasstoyanii naprimer
nablyudaem raznye galaktiki po svoei forme. Na samom dele otpravnoi tochkoi v galaktike yavlyaetsya
1 plotnost' efira, 2 kolichestvo materii,
i 3 kolichestvo energii v etoi galaktike.
Vot voz'mem naprimer est' galaktika, mimo nee proletaet drugaya galaktika, u nih proishodit snizhenie plotnosti
efira mezhdu centrami galaktik, i mezhdu vysokimi i nizkimi plotnostyami efira v rukavah, esli takie est'.
Estestvenno proletaya skvoz' drug druga
v galaktikah dazhe ne bylo sluchaya chtoby dve zvezdy stolknulis' mezhdu soboi, no eto ne znachit chto ne proishodit sliyaniya zvezdnyh mass galaktik. Oni
slivayutsya specificheskim vzaimodeistviem.
Po prichine togo chto plotnost' zvezdy efira, vnutri zvezd sbalansirovana s vneshnei plotnost'yu efira v prostranstve,
to pri priblizhenii centrov galaktik, ili drugih chastei galaktik s nizkimi plotnostyami efira, proishodit lopan'e vneshnih obolochek zvezd, pri lopan'i
obolochek proishodit sbros materii ot desyati do pyatidesyati procentov, massy zvezdy. Posle sbrosa, proishodit bol'shoi vybros efira iz zvezd, na rukavah
i v galaktikah etot process viden v vide rozovyh lopayushihsya zvezdnyh bul'bashek.
Pri bol'shom skoplenii sosednih zvezd, poluchaetsya udarnaya volna
kotoraya na krayah processa budet sbivat' davleniem vneshnyuyu obolochku so zvezd, chto budet privodit' v vzryvam v stile "Obval karkasa - super nova", po prichine togo chto kogda vneshnyuyu obolochku sduet, a zvezda efira ostanetsya na meste, obolochka potom padaet vo vnutr', i padenie proishodit s takoi siloi
chto zarozhdaetsya zvezda efira i srazu efir vosstanavlivaetsya po prichine bol'shogo kolichestva energii, v svyazi s chem proishodit bol'shoi vzryv analogichnyi
Krabovidnoi tumannosti, posle vzryva v centre ostalas' tol'ko isparyayushayasya zvezda efira, vosstanovlenie kotoroi postoyanno podderzhivaet usloviya dlya razleta
materii ot zvezdy s kotoroi byla rezko zduta obolochka. Do teh por poka ves' efir ne vosstanovitsya i zvezda efira ne ischeznet, budet prodolzhat'sya razbros
materii, posle chego materiya ostanovitsya, tak kak materiyu na stol'ko daleko razbrosalo, to eta materiya nikogda v zvezdu ne soberetsya, ona budet uvlechena
drugimi zvezdami.
Tak vot chto sobstvenno imeem, po razmeru zvezdy mezhdu soboi ne sil'no otlichayutsya, s moei tochki zreniya ne bolee chem plyus minus v desyat' raz po sravneniyu s Solncem. Zvezdy odinakovogo razmera pri nizkom davlenii efira zvezdy svetyat slabo, pri bol'shom svetyat sil'no. Pri narushenii
balansa, zvezda lopaetsya pri snizhenii, uvelichivaet yarkost' pri plavnom uvelichenii plotnosti, i teryaet vneshnyuyu obolochku pri vneshnei udarnoi volne.
A kak eto vliyaet na formu samoi galaktiki?, - Mozhno vernutsya v nachalo i posmotret' chto u galaktik v ciklichnosti mozhno vydelit' - molodost', molodost'
mozhno opredelit' kak ustoichivo holodnoe sostoyanie, v etom sostoyanii ravnomernoe raspredelenie zvezd. Galaktiki razmytye.
Vstrecha s drugimi galaktikami
ili samouplotnenie galaktiki, pri etom proishodit plavnoe uvelichenie srednei temperatury vnutri galaktiki, s estestvennym umen'sheniem kolichestva efira v
galaktike. Galaktiki s sinimi rukavami.
Tak kak process vzaimnogo sblizheniya zvezd v galaktike uvelichivaetsya, poyavlyaetsya sleduyushee sostoyanie galaktiki
- sbalansirovannaya, ili galaktika nabravshaya kriticheskuyu massu - na fotografiyah u etih galaktik sootnoshenie sinih zvezd i rozovyh lopayushihsya v rukavah
- primerno odinakovoe.
Sleduyushaya situaciya kogda galaktika v sostoyanii samo-nagreva, i yavlyaetsya peregrevayusheisya, po prichine togo chto posle vybrosa
efira iz zvezd i sbrosa zvezdami bol'shogo kolichestva massy, eta massa v kosmose nachinaet nagrevat'sya, ne davaya uiti izlucheniyu zvezd iz galaktiki, chto
privodit k rezkomu povysheniyu davleniya efira vnutri vsei galaktiki. Vneshne eto zheltovatogo cveta galaktiki, ili galaktiki okruzhennye kol'com gryaznyh
vybrosov meshayushih ih nablyudat'.
Galaktika perehodit v sleduyushee sostoyanie - ustoichivo goryachaya, i v rezul'tate bol'shogo davleniya efira proishodit
razbros vsego sto est' vnutri galaktiki, efira, materii zvezd, i uskorennoe vosstanovlenie efira so zvezd efira delaet etot process grandioznym po
masshtabu, chto mozhet tak razbrosat' zvezdy daleko, chto oni uzhe v etoi galaktike ne soberutsya, a prisoedinyatsya k drugoi.
Estestvenno posle razbrosa
zvezd na bol'shoe rasstoyanie proishodit ih ostyvanie, i zvezdy perehodyat v dostatochno ustoichivoe holodnoe sostoyanie, posle chego, razletevshayasya materiya
obratno padaet na zvezdy i oni nabirayut moshnosti svecheniya, i sblizhayutsya drug s drugom, i tak process prodolzhaetsya.
Ya special'no ne ukazyval na
zvezdnye fotografii - po toi prichine chtoby kazhdyi zhelayushii imel vozmozhnost' vybrat' to chto emu nravitsya dlya kazhdogo sluchaya.

Prodolzhenie.
2 Gryazevoe kol'co.
a) Galaktika men'she gryazevogo kol'ca. b) Galaktika bol'e gryazevogo kol'ca. v) Razmytie gryazevogo kol'ca.
Kogda galaktika prohodit kriticheskuyu massu u ee zvezd nachinaetsya lopan'e zvezd s obrazovaniem vokrug galaktiki gryazevoi peleny,
posle
chego eta pelena koncentriruetsya v gryazevoe kol'co.
Kogda vidimyi razmer galaktiki men'she gryazevogo kol'ca - govorit o tom chto galaktika vstupila v svoyu samuyu dinamichnuyu
fazu, i u nee nachinayut izmenyatsya vse zvezdy vnutri kol'ca.
Povyshaetsya temperatura
v svyazi s chem snizhaetsya plotnost' efira, v svyazi s bol'shimi rasstoyaniyami efir s periferii ne mozhet popolnitsya, zvezdy nachinayut bystro samo-sblizhat'sya, chto
privodit k eshe bol'shemu snizheniyu plotnosti efira i uvelicheniyu temperatury, chto privodit k potere balansa dlya formirovaniya "zvezdy efira" vnutri
zvezd, i v svyazi s chem prakticheski vse zvezdy odnovremenno nachinayut vydelyat' efir.
Kogda
zvezdy vnutri gryazevogo kol'ca - to proishodit ili process bystrogo samo-sblizheniya zvezd po prichine togo chto efir s periferii ne mozhet popolnit' snizhenie plotnosti
tak kak efir tozhe obladaet vyazkost'yu i massoi, i na takih bol'shih rasstoyaniyah popolnenie efira iz vne gorazdo men'she chem nuzhno dlya zvezd, i oni samo-sblizhayutsya,
tem samym eshe bol'she snizhaetsya plotnost' efira i povyshaetsya temperatura, posle chego "zvezdy efira" teryayut balans vo vtoroi raz, v pervyi raz oni
poteryali balans pri formirovanii gryazevoi peleny, kotoraya prevratilas' v gryazevoe kol'co. Teryaya balans po vsasyvaniyu efira, zvezda efira nachinaet vosstanavlivat'
efir i sbrasyvat' ego v prostranstvo, chto proishodit prakticheski odnovremenno so vsemi zvezdami, i galaktika nachinaet razletat'sya. Poluchaetsya chto kogda galaktika
men'she gryazevogo kol'ca, to v nei zvezdy samo-sblizhayutsya, ili rastalkivayutsya efirom.
Kogda zvezdy prakticheski odnovremenno
teryayut balans i vybrasyvayut efir v prostranstvo sozdaetsya izbytochnoe davlenie efira, i zvezdy bystro razletayutsya
vo vse storony, sperva zaletayut za gryazevoe kol'co, a potom
i polnost'yu gryazevoe
kol'co pogloshayut kak budto ego i ne bylo.
