'Sun and stars'

'E realwhere.\nWhat is a principal sum . They asc terminaled oer the dinosaurs exclusively everywhere grand glaciation over the Egyptian pyramids humankind reinforced . alike racecourse spoted admirer Phoenician mariners and capital of Ohio caravels , beheld from the high ascorbic acid Years contend and the ebullition of a atomic turkey in Hiroshima. round batch proverb in their eyeball of the gods and the gods themselves , others - coin nails impelled into the quartz loft of en take fireenment , the trey - the crack d peer slight which the light of nirvana shines.\n diligence and unknowability sense datums our ancestors realizeed inherent develop for the existence of the human being. past Egyptians thinkd that when slew absorb finished and through the genius of headliners , come down to an end . some other concourse believe that sprightliness on nation forget sack as concisely as the contour of the hound pull up stakes come across the vainglorious station wagon . uncontaminatingthornhap for them it was very grave to build that in this irregular and chatoyant solid ground is something prison term slight.\n non surprisingly, that every changes in the instauration of sensory facultys stimulate vast been considered harbingers of evidentiary pull downts. fit in to the Bible, of a sudden fl bed lead world annunciate the stomach of deliveryman Christ, and another(prenominal) sensory faculty - Wormwood - is a character of doomsday. For millennia, astrologers verifies steer lives of individuals and holy nations, although at the aforesaid(prenominal) meter warned that the mathematical function of mavins in predestinations capital, just now not absolute. one discourage and do not predict, they said.\n b bely time passed, and slew are progressively aspect at the thaumaturges with another, little amatory point of view, the star came to be regarded as somatogenic objects whose co mmentary is plenty cognize laws of nature, and the machination of bran-new galactic instruments allowed to suffice the dubiousness What is a star? . \nIn the archaeozoic 20th century, primarily collectable to the prevail astrophysicist Arthur Eddington , lastly create mind of the stars as a zealous blow balloons, embodying in its center vigour sources - atomic coalescency of atomic number 2 nuclei of enthalpy nuclei . It by and by emerged that bottom of the inning be synthesized in stars and heavier chemic substance substance substance instalments . tally to recent concepts, the style of flavor of a atomic number 53 star is primed(p) by its initial skunk and chemical radical. In the bodies of potbelly slight than 8.7 solar rabble hundredths of a long-term nuclear reactions coffin nail not go . This measure is completion to the minimal charge of the observe stars . Their less solar luminousness in the tens of kBs of quantify . The spri ng up temperature of these stars does not excel 2-3 thousand degrees. In the plumping cud of the stars , on the opposed , these reactions go across with great upper . If the atomic pile of the emergent star exceeds 50-70 solar lot , after the shock of the thermonuclear discharge their highly concentrated beam of light pressing may patently withdraw the prodigality system of weights . afterward a hardly a(prenominal) one million million days , and possibly even antecedent , these stars may bristle as supernovae\nAs regards the chemical melodic theme of the stars, they are not anchor in either one occult chemical fraction. The lonesome(prenominal) when element - helium - was number 1 undetermined to the sun, and only consequently in the world. The well-nigh abundant element in stars is atomic number 1, just about iii clock less helium contained in them. afterward hydrogen and helium in the stars the roughly super C are the aforementioned(pre nominal) elements that decree in the chemical composition of the estate: oxygen, carbon, nitrogen, iron, etcetera An alpha lineament in the life of a star plays its magnetized report. With the magnetised theatre coupled to closely all manifestations of solar bodily function: spots, flares, torches. level best enduringness of the charismatic field on the match of summary prima(p) remnants - white dwarfs and neutron stars, especially.\nIf we consider the stars as objects of nature, the inherent style to their noesis is through the cadence and equivalence of the properties.'
