white dwarf, neutron star, (super / hyper) new black hole What is the difference astroglide between matter-State in the white dwarf and neutron stars? For both indicated a balance between gravitational collapse and the Pauli exclusion principle, which states that two particles of matter (proton astroglide / neutron) can not occupy a common space. If the Pauli principle says that two neutrons can not occupy a common space, how can then develop a black hole which is significantly denser, and which is stated to be developed if the mass of the star exceeds 5 times the mass of our Sun? When lead to an explosion stars (emergence of new ones) and how can arise when elements heavier than iron which reportedly can not occur in the core of the star during its life? rtzhrs Posts: 2 Joined: 06/24/2009 19:55

Pauli prohibition astroglide applies to both the electron and neutron, see: http://hyperphysics.phy-astr.gsu.edu/hbase/pauli.html#c2. In white dwarfs, the gravity resists astroglide degenerative pressure of electrons: http://hyperphysics.phy-astr.gsu.edu/hbase/astro/whdwar.html#c3, while the neutron star gravity astroglide opposes the degenerative pressure of neutrons: http: // hyperphysics .phy-astr.gsu.edu / HBAs / astro / pulsar.html # c3. rtzhrs wrote / s: If the Pauli principle says that two neutrons can not occupy a common space, how can then develop a black hole which is significantly denser, and which is stated to be developed if the mass of the star exceeds 5 times the mass of our Sun. ? If the pressure exceeds gravity neutron star but kolapsira into a black hole. rtzhrs wrote / s: When lead to an explosion stars (emergence of new ones) and how can arise when elements heavier than iron which reportedly can not occur in the core of the star during its life? Until phenomenon occurs in binary systems: one of the stars, which changes into a red giant, it may lose some of its hydrogen, its contact with another star - a white dwarf - triggering fusion. http://hyperphysics.phy-astr.gsu.edu/hbase/astro/nova.html#c1 shrink Posts: 9685 Joined: 9/4/2004 17:45
I have a pair urašanj and would be very grateful to those who explain them to me. 1) When you type stars in the core of the Sun Mank of hydrogen bonding in helium, the hydrostatic balance in the star upset. Pressure due to fusion in the core does not preclude a more gravitecijskemu pulling and star begins kolapsirati. In this SEGRAVE like any normal gas which he Cuff volume (in accordance with thermodynamics). This happens until the temperature and pressure in the core does not reach the threshold at which helium begins to merge into carbon. when fusion is put back again uspostavi balance. When this happens, the outer part of the star greatly inflates. Later the star during boot Fuzi the heavier elements can jump off of yourself and get rid of the wrapper. Why are the outer layers of the star expand? 2) If the star allowing a large, combines elements of all the iron. There is stopped. Iron has the greatest binding energy, astroglide so this is expected. Since the iron core is no longer fusion these convulsions. Collapse is so strong that in many cases, the pressure overcomes the electronic degeneration and pushes electrons in the nuclei of atoms. There is the case of the electron capture K (similarly to beta decay), which means that the proton, electron capture. This generates a neutron and the electron neutrino. Predstavlajm you that in this way formed neutron star, once pressure astroglide due to degeneration astroglide of neutrons stops kolapsiranje. I do not understand why it happens even close to a supernova. astroglide Stars of kolapsiranjem core greatly increases magnituda, all the material is in the external layers but pushes into the room. Whence such a violent reaction. I found some razlg that as a reason indicate a huge number of neutrinos generated in covering K and fly from the stellar core on all sides. astroglide Explanations have not been anywhere more specific, but I can not imagine why an avalanche of neutrino increased astroglide magnituda stars and smashed its outer layers, since neutrinos only bad interreagirajo with substance. 3) If the star did not allow large combines elements only to carbon, oxygen can be. Then the core kolapsira. Sedimentation of the degeneracy of the electron pressure stops. A white dwarf. Even this, however kolapsiranjem between astroglide the outer layers of the core pushes on its own. Why? 4) When the supernova generated elements astroglide heavier astroglide than iron? To create, to require high energy neutrons, which have a rel energy astroglide to overcome the energy barrier and bind to the iron core (Rapid Addition of neutrons astroglide is called the English Slovenian professional terms but I do not know). In one atomic nucleus is bound by much, Potami slowly decays with beta-minus decay of the protons generated astroglide and metals heavier than iron. from where to get these neutrons bind in želzova core. but that those neutrons, resulting in coverage between K
