SOME NEW BLACK STRING SOLUTIONS IN 3 DIMENSIONS

We derive several new solutions in three-dimensional stringy gravity. The solutions are obtained with the help of string duality transformat ions. They represent stationary configurations with horizons, and are surrounded by (quasi)topologically massive Abelian gauge hair, in addi tion to the dilaton and the Kalb-Ramond axion. Our analysis suggests t hat there exists a more general family, where our solutions are specia l limits. Finally, we use the generating technique recently proposed b y Garfinkle to construct a traveling wave on the extremal variant of o ne of our solutions.
