ABSTRACT
We present deep observations of the nearby T-type brown dwarf binary e Indi Bab in radio with the Australia
Telescope Compact Array and in X-rays with the Chandra X-Ray Observatory. Despite long integration times,
the binary (composed of T1 and T6 dwarfs) was not detected in either wavelength regime. We reached 3 j upper
limits of 1.23 # 1012
and 1.74 # 1012
