One of the more curious exact solutions of Einstein gravity is the “C-metric”, a metric representing an accelerating black hole, the force being provided by a cosmic string emerging from the black hole horizon. The black hole is neither isolated, nor static, unless we embed it in AdS and drop the acceleration below the AdS scale – a so called “slowly accelerating black hole”. I will describe how to derive thermodynamics for the non-isolated black hole, including the cosmic string tension as a thermodynamical variable—as a result, a new chemical potential is introduced, the thermodynamic length. I will also discuss a set of extensive variables, or chemical expressions for the black hole that do not involve any reference to the geometrical parameters and describe some critical phenomena for the black hole.
