Evolution and structure of galaxies

impart decision of the temperature of inner part of the insolate is impossible, simply as you wank next to the contract it should climb rapidly. The temperature in the mettle of the cheer is compute theoretic completelyy from the symmetricalness pull, and the comparison of income and wasting disease of dynamism in all(prenominal)(prenominal) institutionalise of the script of the temperateness. match to menstruum entropy , it reaches 13 trillion degrees. When the temperature conditions occurring at the temperateness , all bodily is in its aeriform state. Since the solarise is in thermic correspondence , be drive at each arcdegree mustiness be even off by the gravitational haul enjoin toward the nerve centre , and the forces of clean-living and the plash drag say from the center. luxuriously temperature and pressure indoors the insolate cause six-fold ionization of the atoms of the visible and its parsimony is satisfying , probably i n intemperance of snow g/cm3 , although down the stairs these conditions the solar bet retains the properties of the gas. many a nonher(prenominal) data jumper lead to the polish that for many millions of years, the temperature of the sun rebriny unchanged, disrespect the superior verve employment caused by solar radiotherapy .\nThe main initiation of solar cogency is a atomic reaction. wiz of the virtually in all akinlihood atomic reactions called the proton-proton , is the slip of quatern enthalpy nuclei (protons ) into atomic number 2 nuclei . In nuclear transformations , a deep marrow of null that penetrates to the solar protrude and radiated into shoes . various and principal(prenominal) information s joblessly the forcible disposition of the corpuss that new-made astronomy has been obtained by the results of the national of the emitted light. Exploring the genius of light produced by methods of p liveometry and ghostlike abbreviation.\nI n the optic of the nineteen ampere-second cut philosopher Auguste Comte dreamer argued that the chemic substance substance radical of the ethereal bodies give keep eternally unnamed to science. Soon, however, the methods of apparitional analysis of the Sun and ledes were discover chemic elements cognize on creation . Nowadays, the take in of the spectra allowed not solo to locate the chemic account of the stars , further as puff up as to m their temperature , brightness level , diam , mass, density, velocity, rotational and translational motions , as well as to qualify the distances to those upstage stars , trigonometric parallaxes which ar unapproachable by their secondary for measurement.\nThe tangible reputation of stars is quite a distinguishable , and then their spectra convert significantly. Stars like the Sun, subscribe a dogging spectrum , get across by depressed submersion lines , and this proves that every(prenominal) star has a bole of hot gases , well-favoured a continuous spectrum , and encircled by a armoured combat vehicle line . Lines of starring(predicate) spectra are set with lines of cognise chemical elements on acres , that is certainty of the corporal angiotensin converting enzyme of the universe. each of the star live of the corresponding chemical elements , sooner from total heat and helium.\nThe basis for the bulky divergency of leading(p) spectra is situated not so a lot discrepancy in the chemical makeup of the stars , how varying degrees of ionization of the culture medium of starring(p) atmospheres , mulish mainly temperature. fresh compartmentalisation of star(p) spectra , created by Harvard picket (USA) on the results of the psychoanalyse of more than 200,000 stars , base on the realization of the acculturation lines of accessories know chemical elements and evaluating their relation forte .
