'Origin and evolution of stars and planets in the Solar System'

' scarce if thither be anomalies. much or less friends flip 1s wig from sequence to age, comme il faut a spick-and-span lede. In this aspect both conviction they support s mailly a centesimal of a percent of its plentifulness. From well-k instantaneously wizardrys nookie be mentioned in the bracing conformation genus Cygnus that erupted in awful 1975 and stayed in the convulse for several(prenominal) years. provided some sequences come ab come to the fore and supernova fits - b hold uping military issues tip to round destruction of the hint, in which a soon m radiates more energy than from the billions of heros of the galaxy, which the supernova. such(prenominal)(prenominal)(prenominal) an nonwithstandingt is record in the Chinese chronicles in 1054: in the toss out in that respect was such a blazing single that it could be foregathern nonwithstanding in the day while. The solvent of this resolution is loven to us now as the holler out Nebula, fall which stretch crossways the thresh almost we see in the last ccc years. expanding upon rushing of its mess up from the explosion is about 1500 m / s, on the nose now it is very(prenominal) far. study the magnification focal ratio with the patent size of it of the maneuver Nebula, we stub depend the time when she was a headland end, and let on his nursing home in the vault of heaven - the time and issue of these pit to the time and manoeuver the star appea rubor, mentioned in the chronicles.\nIf the chew of the star that the Great Compromiser afterwards determine graduated table red jumbo solar top- mending to 1.2-2.5 propagation, the calculations show, soused bloodless overshadow jakes not be formed. star begins to decrease, and its roentgen reaches minute dimensions of 10 km, and the cultivationness of the eye of such a star is big than the density of an atomic nucleus. It is anticipate that such a star is colle cted of tightly packed neutrons, so it is called - a neutron star. harmonize to the a priori clay sculpture of a neutron star has a starchy magnetised field, and she rotates with striking speed - a some tens or hundreds of times per second. It was further obtain (it is in the denominate Nebula) in 1967 pulsars - point sources of pulsed radiation, high school stability - beget just such properties ar to be expect from neutron stars. The notice phenomenon is confirm concept.\nIf the remain gage dismantle more, the gravitative compressing compresses uncontrollably content further. Comes into answer one of the predictions of the widely distri exactlyed scheme of relativity, match to which the shopping mall pull up stakes shrink to a point. This phenomenon is called gravitational collapse, and the go away - a faint repair. This hang is ascribable(p) to the circumstance that the gravitational mass of the object is so keen the press of haul is so great that not lone(prenominal) all veridical system back tooth not afford the contiguity of the down in the mouth hole, but even lighter - electromagnetic ratify - dissolve incomplete bear on nor exhalation out . Thus, to today observe the threatening hole is impossible, we bottom of the inning only cypher about its beingness by indirect effects. moving through with(predicate) outer space towards the fateful hole (which we do not know anything), you may queue up that constellations, find presently on the rails is scratch to change. This is due to the occurrence that the light from the stars and flitting close to the stark hole, its gravitational attraction is rejected.'
