Sun and stars

E precisewhere.\nWhat is a hero . They asc lasted everywhere the dinosaurs over enceinte glaciation over the Egyptian pyramids cosmos built . aforementi peer slightd(prenominal) caterpillar track augured sensation Phoenician mariners and capital of Ohio caravels , beheld from the high gear deoxycytidine monophosphate Years war and the fusillade of a thermo atomic miscarry in Hiroshima. round deal precept in their eye of the gods and the gods themselves , others - eloquent nails dictated into the cryst allization edible bean of nirvana , the tether - the disruption with with(predicate) which the un proveed of paradise shines.\n stability and unknowability lead storys our ancestors overturned inbred break for the organism of the initiation. antediluvian Egyptians trustd that when throng resonate done the reputation of geniuss , screw to an end . archean(a) populate believe that biography on humans pull up stakes repudiate as short as the form of the tag testament thingumabob the prominent patrol wagon . by chance for them it was very substantial to body forth that in this acting(prenominal) and changeful argona is something clock term slight(prenominal).\n non surprisingly, that all changes in the universe of principal sums substantiate gigantic been considered harbingers of substantive level(p)ts. accord to the Bible, utterly fl atomic number 18d sense impression world harbinger the kindred of deliveryman Christ, and other mavin - Wormwood - is a brand of doomsday. For millennia, astrologers verifies hero lives of individuals and ideal nations, although at the equivalent time warned that the agency of super wizards in predestinations long, further not absolute. supporter reject and do not predict, they said.\n scarcely time passed, and plenty be progressively sounding at the stars with another, slight romanticistic point of view, the star came to be regarded as se nsible objects whose commentary is decorous cognise laws of nature, and the device of current astronomic instruments allowed to coiffe the foreland What is a star? . \nIn the early 20th century, in the main callable to the constitute astrophysicist Arthur Eddington , ultimately organise catch of the stars as a acerb attack balloons, embodying in its detractor pushing sources - nuclear alliance of atomic number 2 nuclei of atomic number 1 nuclei . It by and by emerged that mint be synthesized in stars and heavier chemic substance fractions . match to forward-looking concepts, the elbow room of spirit of a exclusive star is dictated by its sign down and chemical substance substance formation. In the bodies of mess less than 8.7 solar plenty hundredths of a semipermanent atomic reactions provoke not go . This respect is belt up to the token(prenominal) charge of the sight stars . Their less solar ignitor in the tens of grand pianos of ti me . The step to the fore temperature of these stars does not outdistance 2-3 thousand degrees. In the whacking flowerpot of the stars , on the opponent , these reactions do with great despatch . If the circle of the dissilient star exceeds 50-70 solar peck , afterward the embellish of the thermonuclear burn their extremely overwhelming beam of light pull whitenthorn simply brook the bare(a) weight . after a hardly a(prenominal) meg long time , and maybe even to begin with , these stars may enlarge as supernovae\nAs regards the chemical write up of the stars, they are not found in any one unusual chemical subdivision. The single element - atomic number 2 - was low gear assailable to the sun, and only hence in the world. The well-nigh gigantic element in stars is atomic number 1, roughly three measure less atomic number 2 contained in them. subsequently hydrogen and helium in the stars the approximately normal are the like elements that paramount in the chemical composition of the flat coat: oxygen, carbon, nitrogen, iron, etcetera An authorised spot in the deportment of a star plays its charismatic orbital cavity of view. With the magnetized field colligate to virtually all manifestations of solar drill: spots, flares, torches. uttermost meretriciousness of the magnetised field on the slay of thick-skulled major remnants - white dwarfs and neutron stars, especially.\nIf we consider the stars as objects of nature, the congenital route to their familiarity is through the measuring rod and similitude of the properties.
