Abstract
We argue that the temperature of the stellar phase is likely a monotically decreasing function of radius in the central regions of elliptical galaxies with cusps. We show that it requires the presence of a central mass concen tration. An estimate of its minimum mass based on few parameters is given. This lower bound is consistent with current mass values of the central obje cts in galaxies derived from detailed models.
