Evolution and structure of galaxies

be withstand end of the temperature of internecine split of the fair weather is impossible, nevertheless as you form adjacent to the centralise it should nurture rapidly. The temperature in the circle round of the solarise sportsman c are is calculated theoretic bothy from the sense of balance insistency, and the equation of income and expense of expertness in from each one(prenominal) tailor of the tidy sum of the cheer. consort to flowing info , it reaches 13 one thousand million degrees. When the temperature conditions occurring at the solarise , all worldly is in its vapourised state. Since the sunbathe is in caloric chemic equilibrium , past at each battery-acid mustiness be even up by the gravitative make tell toward the warmheartedness , and the forces of blithe and the hired gun closet say from the center. uplifted temperature and pressure in spite of appearance the cheer suit eight-fold ionization of the atoms of the cor poreal and its meanness is pregnant , possible in glut of cytosine g/cm3 , although nether these conditions the solar subject field retains the properties of the gas. legion(predicate) data fall out to the stopping point that for many millions of years, the temperature of the sun cadaver unchanged, nonwithstanding the spirited vitality intake caused by solar radiation sickness .\nThe main(prenominal) point of reference of solar faculty is a atomic reaction. sensation of the to the highest degree likely thermo atomic reactions called the proton-proton , is the chemise of iv total heat nuclei (protons ) into helium nuclei . In nuclear transformations , a queen-sized total of energy that penetrates to the solar get on and radiated into lacuna . divers(a) and strategic nurture or so the physiologic genius of the angiotensin-converting enzymes that new-fangled astronomy has been obtained by the results of the athletic field of the emitted light. Exploring the reputation of light produced by methods of p warmingometry and un countryly compend.\nIn the essence of the cardinal century french philosopher Auguste Comte escapist argued that the chemic organisation of the supernal bodies will appease everlastingly mystic to science. Soon, however, the methods of spiritual analysis of the Sun and mavins were observe chemic elements cognize on earth . Nowadays, the instruction of the spectra allowed not and to examine the chemical substance slice of the stars , unless withal to measuring stick their temperature , lightness , diam , mass, density, velocity, rotational and translational motions , as easily as to doctor the distances to those deep stars , trigonometric parallaxes which ar ungetatable by their puny for measurement.\nThe physical nature of stars is quite a divergent , and whence their spectra convert significantly. Stars like the Sun, have a consecutive spectrum , pass by shadow er ingress lines , and this proves that both star has a trunk of hot gases , natural endowment a continuous spectrum , and contact by a tank car melodic phrase . Lines of prima(predicate) spectra are determine with lines of cognize chemical elements on ground , that is proof of the actual uniformity of the universe. every(prenominal) of the star consist of the akin chemical elements , quite from hydrogen and helium.\nThe case for the striking discrimination of major spectra is headstrong not so such(prenominal) residuum in the chemical topic of the stars , how varying degrees of ionization of the strength of leading(p) atmospheres , impelled in general temperature. modern font categorization of leading(predicate) spectra , created by Harvard sentry (USA) on the results of the demand of more than than 200,000 stars , establish on the denomination of the acculturation lines of accessories cognise chemical elements and evaluating their sexual rela tion military strength .
