  The low-mass star formation region associated with the reflection nebula
Cederblad 110 in the Chamaeleon I cloud was mapped with the Australian
Telescope Compact Array (ATCA) at 6 and 3.5cm. Altogether 11 sources were
detected, three of which are previously known low mass young stellar objects
associated with the nebula: the illuminating star IRS2 (Class III, Einstein
X-ray source CHX7), the brightest far-infrared source IRS4 (Class I), and the
weak X-ray source CHX10a (Class III). The other young stellar objects in the
region, including the Class 0 protostar candidate Cha-MMS1, were not detected.
The radio spectral index of IRS4 (alpha = 1.7 +/- 0.3) is consistent with
optically thick free-free emission arising from a dense ionized region,
probably a jet-induced shock occurring in the circumstellar material. As the
only Class I protostar with a 'thermal jet' IRS4 is the strongest candidate for
the central source of the molecular outflow found previously in the region. The
emission from IRS2 has a flat spectrum (alpha = 0.05 +/- 0.05) but shows no
sign of polarization, and therefore its origin is likely to be optically thin
free-free emission either from ionized wind or a collimated jet. The strongest
source detected in this survey is a new compact object with a steep negative
spectral index (-1.1) and a weak linear polarization (about 2 %), which
probably represents a background radio galaxy.
