- NGC 4725: spiral'naya galaktika s odnim rukavom
(Astronomicheskaya kartinka dnya,
30.05.2013, 1.4 KBait, otvetov: 8)
V to vremya kak u bol'shinstva spiral'nyh galaktik, vklyuchaya nash Mlechnyi Put',
est' dva spiral'nyh rukava ili dazhe bol'she, u NGC 4725 on tol'ko odin.
Na etom chetkom cvetnom sostavnom izobrazhenii edinstvennaya
"chudesnaya spiral'" zakruchivaetsya vokrug centra galaktiki, vyhodya iz yarkogo
kol'ca golubovatyh skoplenii novorozhdennyh zvezd i krasnovatyh oblastei zvezdoobrazovaniya.
V etoi strannoi galaktike vidny takzhe polosy pogloshayushei svet pyli,
horosho zametnoe kol'co i zheltovataya central'naya peremychka, sostoyashaya iz bolee staryh zvezd.
Diametr NGC 4725 prevyshaet 100 tysyach svetovyh let, ona nahoditsya na rasstoyanii v 41 million svetovyh let
v sozvezdii Volosy Veroniki.
Komp'yuternoe modelirovanie formirovaniya odinochnogo
spiral'nogo rukava pozvolyaet predpolozhit', chto po otnosheniyu k
napravleniyu vrasheniya vsei galaktiki on mozhet byt' kak lidiruyushim, tak i
otstayushim.
Na fotografii takzhe vidna chut' men'shaya po razmeru fonovaya galaktika s vpolne tradicionnoi spiral'noi
strukturoi.

1 Rassloenie galaktiki.
U galaktik nablyudaetsya rassloenie vnutri
galaktiki, v svyazi s chem proishodit neravnomernoe
uplotnenie zvezd, i sozdaetsya situaciya kogda v centre
galaktiki proishodit povyshenie temperatury v
svyazi s chem sozdaetsya razryazhenie efira

v svyazi
s bol'shimi rasstoyaniyami efir ne mozhet byt'
popolnen s okrain galaktiki, zvezdy nachinayut
v centre bystree sblizhat'sya
i styagivat'sya v centr galaktiki, posle chego nizkaya
plotnost' efira privodit k tomu chto zvezdy nachinayut
teryat' balans i uzhe ne mogut vsasyvat' efir,
chto privodit
k lopan'yu zvezd s posleduyushim vybrosom efira.
Posle togo kak povyshaetsya davlenie efira v centre galaktiki,
povyshaetsya davlenie efira, poluchaetsya situaciya v kotoroi
staraya ploskost' galaktiki s vysokoi plotnost'yu
efira sozdaet uprugost' gorazdo bol'shuyu po otnosheniyu
k osyam, v svyazi s chem vse zvezdy povorachivayutsya po osi,
i poluchaetsya vot takaya situaciya.

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.

Rukava.
Esli galaktika sostoit iz yavno vidimyh dvuh rukavov,
to eto rukava ot sliyaniya dvuh galaktik.

Dannaya galaktika samaya interesnaya iz vseh, u etoi galaktiki proizoshlo sliyanie dvuh
galaktik, chto povleklo za soboi rezkoe rassloenie zvezd, i u centra galaktiki zvezdy
nachali bystro samo-sblizhat'sya i rezko uvelichilas' temperatura v centre, i estestvenno
rezko snizilas' plotnost' efira, i zvezdy v centre ne mogut obespechit' nuzhnogo
davleniya vnutri sebya chtoby uderzhat' zvezdu efira ot togo chtoby chasticy Aleksandra,
ne nachali prevrashat'sya v chasticy efira. Pri vosstanovlenii chastic Aleksandra, k etim chasticam
prisoedinyaetsya energiya, i chastica uvelichivaet ob'em v milliard i bolee raz, i prevrashaetsya
v chasticu efira (chastica efira v milliard raz men'she chasticy (uslovnoi chasticy) vozduha),
pri etom process na nekotoroe vremya stanovitsya neobratimym. Pri blizko raspolozhennyh sosednih
zvezdah, rezko vosstanovivshiisya efir u sosednih zvezd delaet bokovoi rezkii gidravlicheskii udar pri etom
mozhet sdut' vneshnyuyu obolochku, i zvezda efira ostanetsya pozadi a obolochka iz materii sletit.
I pervonachal'noe vosstanovlenie efira nabiraet lavinoobraznyi vid, chto v rezul'tate tak daleko
davleniem efira razbrosaet zvezdy, chto bol'shinstvo zvezd nikogda ne soberutsya v odnu galaktiku,
oni pri ostyvanii sformiruyut mnogo nebol'shih galaktik na bol'shom udalenii drug ot druga.
Osnovnaya dostoprimechatel'nost' etoi galaktiki - eto samaya dinamichnaya chast' zhizni galaktiki.
To chto hotyat sdelat' katalog - to eto konechno gde-to logichno, no ne sovsem pravil'no, pravil'no u analogichnyh
galaktik vesti nepreryvnuyu videozapis' v teleskop.
No uchityvaya v kakom kamennom veke zhivem chto opredelyaetsya kolichestvom teleskopov v kosmose na million ,
etot vopros budet vryad-li kogda reshen v obozrimom budushem.
