WebAn important black hole observable is the Bekenstein-Hawking (BH) entropy, which is proportional to the area of the event horizon, SBH = Ah / (4 G ). For the 3-brane solution (3.1), the horizon is located at r = r0. For r0 > 0 the 3-brane carries some excess energy E above its extremal value, and the BH entropy is also non-vanishing.
