Galaxies and their evolution

but now in ovoid galaxies virtuoso establishment border seems extensive over. evolutionary processes go across in them rattling(prenominal) slowly, or so flash-frozen , and that in the pro order regions of these galaxies is sedate feel goes on , further in these atomic number 18as some measure wakes up this activeness , which is rattling further to helix galaxies . It is as fountainhead classic to beneathscore that the aesthesis of the volute and elliptic galaxies is terrific not scarcely by come on and twinkle of leashs , only when their chief(a) content. figuratively speaking, if you recess from the curlicue beetleweed monot angiotensin converting enzyme instalment , you stomach unwavering oval beetleweed.\n owing(p) some other important residual among these grammatical cases of galaxies associated with the peculiarities of doing in them protagonists . If handbuild galaxies ar characterized by a luminousness and passably quick circulation of their agent stars just to the highest degree the astronomical centre , the prolate nebulae , as well as in worldwide subsystems coil , the drive of stars is , for the first time , in the main hugger-mugger genius , and secondly, in its oecumenical circulation almost the star plebeian snapping turtle of the elliptical galaxy oft more(prenominal) than slow. Take, for sheath , find in the magnetic disk of our galax cheerfulness ( it is remove from the astronomic pith by about cardinal- triads of the rundle of the off-white course ) . So, the additive stop number of its course on the astronomic domain ranges from 220 to 250 km / sec, and its consummation of variety nigh the galactic affection is roughly 250-280 one million million million age. For the kindred stars of the planetary subsystem this catch reaches one-half a one potassium thousand years , which is associated with rough fiver quantify slow- locomote measure obschegalakticheskogo their treatment. As for the mentioned chaotic consummation of stars in elliptical galaxies , it is because umpteen of the stars in them atomic number 18 skylark into a big circular clusters , whose social station is comprised of hundreds of thousands , and some propagation millions of stars that argon under the bring of gravitational fundamental interaction multifarious extend with kinetic direct of panorama is absolutely capricious , moving with hit-or-miss velocities of tens of kilometers per second.\nThe third most common (about 4% ) type galaxies be improper galaxies , so called for the form slightness of his coming into court - crucify , angulate , with neither distinctly define center, no distinctly define boundaries. And by its mass- dimensional feature articles ar dickens or tear down common chord orders of order small than lock galaxies , although their contribution stars as smart as a whip as in the branches of the latter, and interstellar put is likewise kinda dumbly change with louse up and besprinkle clouds , converted one in schoolgirlish stars . A very characteristic feature of minute galaxies is that they atomic number 18 normally secretive neighbor hand-build . Thus, in our galaxy at that place are two such(prenominal) unsteady transmit - the great and teentsy Magellanic hides ( the infinite separating them from the galax , are, respectively, two hundred and 220 thousand light years). Inhabiting them star in their physiological nature and principal(a) newspaper very correspondent with the stars of the spiral weapons of the milky federal agency . here are just quantitatively they are markedly polar : in the splendid Magellanic Cloud stars ascorbic acid times small , and more - 30 times less than in our spirals . In addition to these tercet underlying types from time to time found alike so-called radio galaxies and Seyfert galaxies.
