We show how in gravitational collapse the Hawking radiation at large times is precisely related to a scaling limit on the sphere where the star radius crosses the Schwarzschild radius (as long as the back reaction of the radiation on the metric is neglected). For a free quantum field it can...
The reduced radius for the circular orbit is in agreement to first-order with that calculated from the Schwarzschild effective potential. The method of solution is understandable by undergraduate students. 展开 关键词: Theoretical or Mathematical/ celestial mechanics geometry physics education Schwarzschild...
In the exterior Schwarzschild field, for example, these expressions differ by terms of m 2 order 7" For a further discussion of these and other choices for the potential the reader may turn to Remark 1 of Section 3. From my point of view, however, the ultimate choice should be made via...
The constants are evaluated as natural unit frequency equivalents of the neutron, electron, Bohr radius, Rydberg constant, Planck's constant, Planck time, a Black hole with a Schwarzschild radius, the distance light travels in one time unit;and the fine structure constant. These constants are ...
