Abstract: 
I will be discussing the computation of superstring scattering amplitudes in the presence of D-branes and orientifold planes. The results encode certain terms in the low energy effective actions of space-time fields localized on branes/planes. I will describe some of these interactions and show how they restore compatibility with T-duality.
