BPS D0-D6 branes in supergravity

Abstract

We analyse 1/2 BPS IIA Dp-brane supergravity solutions with B-fields and their Killing spinor equations. Via probe analysis, we rederive the supersymmetry conditions for D0-Dp with B-fields. In the case of D6 with B-fields, the D0-probe sees a multi-centred BPS configuration where the B-fields give the location of a wall of marginal stability. Finally we go beyond the probe approximation and construct a 1/8 BPS supergravity solution for a fully back-reacted D0-D6 with B-fields. © 2009 SISSA.
