Idea

The D-brane of dimension 1+11+1 in type IIB string theory. Also called the D-string, to be distinguished from the fundamental string.

Properties

S-duality with the fundamental string

Under S-duality the D1-brane mixes with the fundamental string to form the (p,q)-string.

A formalization of this in terms of the homotopy theory of the super L-infinity algebras which constitute the respective extended super spacetimes is in (FSS 13).

Bound states

bound states/brane intersections involving D1-branes:

Black hole entropy

At low string coupling D1-D5 brane bound states are described by 2d CFT, which is well understood. After passage to the corresponding strongly coupled black brane configurations in type IIB supergravity, which are black holes in the given compactification, the entropy of these 2d CFTs matches the Bekenstein-Hawking entropy of these black holes. See at black holes in string theory for more on this.

This is parts of the AdS/CFT correspondence. See (AGMOO, chapter 5).
