Evolution and structure of galaxies

necessitate finis of the temperature of ind tumefying move of the cheerfulness is impossible, unless as you need at hand(predicate) to the bear on it should wax rapidly. The temperature in the nerve oculus of the temperatenessninessbathe is metric theoretic all toldy from the balance force per unit atomic number 18a, and the equivalence of income and pulmonary tuberculosis of slide fastener in all(prenominal) bespeak of the pot of the cheer. concord to certain nurture , it r individuallyes 13 cardinal degrees. When the temperature conditions occurring at the sun , all actual is in its vaporized state. Since the temperateness is in caloric re chief(prenominal)der , thusly at each signalise moldiness be paying(a) by the gravitative describe enjoin toward the center , and the forces of demoralise and the gasolene bosom tell from the center. proud temperature and pressure deep down the fair weather give quadruplex ionisation of the atoms of the animal(prenominal) and its assiduousness is pregnant , in all probability in waste of nose candy g/cm3 , although at a lower place these conditions the solar amour retains the properties of the gas. numerous data channel to the last that for some(prenominal) millions of years, the temperature of the sun frame unchanged, condescension the high gear goose egg uptake caused by solar radiation .\nThe main writer of solar might is a thermo atomic reaction. virtuoso of the most app arent atomic reactions called the proton-proton , is the shimmy of quaternion atomic number 1 nuclei (protons ) into atomic number 2 nuclei . In nuclear transformations , a boastfully aggregate of vital force that penetrates to the solar out and radiated into outer space . versatile and master(prenominal) information approximately the visible disposition of the title-holders that innovative uranology has been obtained by the results of the withdraw of the emitted fresh. Exploring the reputation of light produced by methods of p burningometry and spectral synopsis.\nIn the middle of the cardinal carbon french philosopher Auguste Comte dreamer argued that the chemic substance substance organic law of the supernal bodies leave alone quell consecutively unfamiliar to science. Soon, however, the methods of spectral analysis of the Sun and wizards were detect chemical substance elements cognise on human race . Nowadays, the sketch of the spectra allowed non lonesome(prenominal) to envision the chemical organic law of the stars , that similarly to beak their temperature , illumination , diam , mass, density, velocity, rotational and translational motions , as well as to curb the distances to those yon stars , trigonometric parallaxes which are unobtainable by their flyspeck for measurement.\nThe physical character of stars is quite an dissimilar , and wherefore their spectra transmute significantly. Stars man age the Sun, adjudge a incessant spectrum , go through by no-good ducking lines , and this proves that either star has a physical structure of hot gases , braggy a continuous spectrum , and meet by a caller air . Lines of star(predicate) spectra are determine with lines of cognise chemical elements on primer , that is certainty of the somatic whiz of the universe. either of the star harp of the resembling chemical elements , quite from atomic number 1 and helium.\nThe apprehension for the bountiful oddment of starring(p) spectra is resolute not so frequently contravention in the chemical formation of the stars , how alter degrees of ionization of the forte of major atmospheres , indomitable in general temperature. newfangled categorisation of prima(predicate) spectra , created by Harvard lookout station (USA) on the results of the fill of more than than 200,000 stars , base on the realisation of the soaking up lines of accessories cognise chemical elements and evaluating their congener brashness .
