Black hole of Schwarzschild
See also: Black hole (homonymy)
In Astrophysical, the black hole of Schwarzschild is the Black hole obtained by solving the equation of Einstein of the General relativity, for the case Statique and Isotrope. It is the simplest shape of black hole, with a electric Charge and a Angular momentum null. The black hole of Schwarzschild, also called Métrique of Schwarzschild was obtained the first time by Karl Schwarzschild shortly after the publication of the theory of the General relativity by Albert Einstein in 1915.
Properties
The theorem of Birkhoff
A Théorème remarkable due to Birkhoff affirms that the metric one of Schwarzschild is the single solution with the equations of Einstein in the vacuum having spherical symmetry. As the metric one of Schwarzschild is also static, this shows that in the vacuum any spherical solution makes some is automatically static. One of the interesting consequences of this theorem is that any pulsating star which remains with spherical symmetry cannot generate gravitational waves (since the area of the space time external with star must remain static).
The theorem of baldness
The Théorème of baldness is a particular case of L “ absence of hair ” of the black holes. Indeed, whatever the composition of the Celestial body which could crumble on itself to give a black hole, if this collapse were done in a spherical way then the result is necessarily a black hole of Schwarzschild which, except the total Masse, keeps any information, no trace of the body being broken down and which gave him birth.
