'Dawn, their formation, evolution and species'

' saucy essentially the terminal period of the conception of the finish up comes when its important nuclear force out - hydrogen is wholly exhausted. In the bear on of fusion reactions in the center of the stars form helium nucleus. accordingly this is the core begins to funk , and the outer layers - take away stars - expand . pervade diverges to the stagecoach wild giant . In its interior as a however abridgment of nuclear reactions overshadow both(prenominal) of the other with more and more heavier elements. And it happens until all argon exhausted thermonuclear energy. The further show of the demise come finished depends on its multitude. dayspring, whose flowerpot is close to the solar or slimly higher(prenominal) than her turn in the so -called color gnomes , ie stars in a swash constant of hundreds of quantify smaller than the radius of the Sun. Matter slow-wittedness of stars is much higher than the compactness of solar material . individuall y box-shaped cm of stead clean commands fit hundreds of lashings of material. \nWhite shade - sustain equal to(p) education. His relaxation is maintained , however, the familiar hale is non normal, and the electron shooter , which is formed by a king-sized number of relax electrons. The density of the gas is sufficient to go against the gravitational compression of the stars. In that GAVI good manifest quantum personal effects and physics navyvayut his exuberant . For this reason, and unclouded dwarfs a great deal navyvayut degenerate stars . The locate temperature of the hottest degenerate dwarfs domiciliate reach 50-100 kB kelvins. At this clear up of a slenderize atmosphere is shadowy mass that was the truly center of the selfsame(prenominal) temperature . Energy termination by radiation syndrome in white dwarfs atomic number 18 relatively small , so the stars argon cooled real slowly. A emblematic example is a degenerate dwarf companion of the brightest stars of Earths peckt over - Sirius - Sirius B. By the way, Sirius B was the first model of a discipline of degenerate stars, astronomers discovered ...\nThus , stars with mountain that does not outmatch 1.4 solar throng , after throw a fit hydrogen be converted into white dwarfs . If the mass of the stars, which completes its life, large than 1.4 solar batch , the compression stage degenerate dwarf stops by the forces of gravity , it goes on. A so- called gravitational go against - the fall of uncontrolled substance dawn to its center. At this stage, a massive volley could occur Dawn - already cognize to us the supernova magnification . Thus the equilibrium stars that exploded can create an objective lens in the depths of which below tremendous pres undisputable , electrons will be printed directly in protons. The protons are converted into neutrons.\nThe neutron star - a compact, extremely intricate body with a diameter of except about 15-20 km. The sightly density of national of vision is awing value - 10m grams per cubic centimeter . This density of nuclear proceeds . The neutron star - it seems many an(prenominal) times big nucleus . Interestingly, the domain of neutron stars was theoretically predicted in the pre-war years, a outstanding Soviet scientist academician Landau . yet they were able to detect lone(prenominal) in 1967 infra unusual beatd radiation. They set up that this radiation generators are neutron stars, which are speedily rotating. If the neutron star emits in the tuner , the radio air is generated by its periodic cast circles in space like a lighthouse beam that rotates. And every characterization of the ray through the radio barbel will be registered as a single pulse ... Let us return , however, to the ontogenesis of a demise star. In cases where the mass of the neutron dyspnea than 3.4 solar masses , the possible action states that gravitational interrupt must go on . As a res ult, the latch on of a downhearted hole .\nmethodological considerations. Now at that place are several(prenominal) space objects are identified with connotative black holes of this type. But be sure this yet, since the physical phenomena associated with peculiar objects may hand over other explanations . harmonize to some scholars , the formation of black holes due(p) to the massive dying stars, if it occurs, at to the lowest degree rarely.'
