Krüger Radius

The radius of a black hole that can be formed from a collapsing star with a given mass, calculated as

R = 2GM/c^2

, a key parameter in stellar collapse models.

The statement of the theorem

The Schwarzschild radius

R_s

, representing the radius at which the escape velocity equals the speed of light, is defined solely by the mass

M

of the object: \n

R_s = \frac{2GM}{c^2}

\nwhere

G

is the gravitational constant,

M

is the mass, and

c

is the speed of light.
