Tachyon hair increases Hawking temperature

New two-dimensional black hole solution with tachyon field

Abstract

Using a combination of analytical and numerical methods, we obtain a two-dimensional spacetime describing a black hole with tachyon hair. The physical ADM mass of the black hole is finite. The presence of tachyon hair increases the Hawking temperature.
