Charged heterotic black holes in four and two dimensions

We consider four-dimensional charged black holes occuring in toroidally compactified heterotic string theory, whose ten-dimensional interpretation involves a Kaluza-Klein monopole and a five-brane. We show that these four-dimensional black holes can be connected to two-dimensional charged heterotic black holes upon removal of the constants appearing in the harmonic functions associated with the Kaluza-Klein monopole and the five-brane.
