Theoretical upper size limit for a star
Webb27 okt. 2024 · This radius, sometimes called the static limit is given by the equation r s = M + ( M − a 2 cos 2 ( θ)) 1 / 2 Notice that this is almost exactly the same as above, except for that extra cos 2 ( θ). This defines a different, slightly larger and somewhat "pumpkin-shaped" horizon which encompasses the inner Event Horizon defined above. WebbLimiting magnitude.
