Probing Near Extremal Black Holes with D-branes
Abstract
We calculate the one loop effective action for D-brane probes moving in the presence of near BPS D-branes. The v2 term agrees with supergravity in all cases and the static force agrees for a five dimensional black hole with two large charges. It also agrees qualitatively in all the other cases. We make some comments on the M(atrix) theory interpretation of these results.
