Abstract
Optical observations of an extended red halo surrounding the galaxy 1E 1111.9-3754 sparked considerable interest as potentially the first de tection of low-mass star formation in an X-ray cooling flow. To test t his possibility, we obtained near-infrared surface photometry of this galaxy at J (1.25 mu m) and K (2.15 mu m) and compare this data with m odels of a low-mass stellar accretion population. Our surface brightne ss measurements are consistent with a normal r(1/4) elliptical galaxy profile and show no evidence of an extended infrared halo, which argue s against the low-mass stellar accretion hypothesis.
