Connecting low- and high-mass star formation: the intermediate-mass
  protostar IRAS 05373+2349 VLA 2
  Until recently, there have been few studies of the protostellar evolution of
intermediate-mass (IM) stars, which may bridge the low- and high-mass regimes.
This paper aims to investigate whether the properties of an IM protostar within
the IRAS 05373+2349 embedded cluster are similar to that of low- and/or
high-mass protostars. We carried out Very Large Array as well as Combined Array
for Research in Millimeter Astronomy continuum and 12CO(J=1-0) observations,
which uncover seven radio continuum sources (VLA 1-7). The spectral index of
VLA 2, associated with the IM protostar is consistent with an ionised stellar
wind or jet. The source VLA 3 is coincident with previously observed H2
emission line objects aligned in the north-south direction (P.A. -20 to -12
deg), which may be either an ionised jet emanating from VLA 2 or
(shock-)ionised cavity walls in the large-scale outflow from VLA 2. The
position angle between VLA 2 and 3 is slightly misaligned with the large-scale
outflow we map at ~5-arcsec resolution in 12CO (P.A. ~30 deg), which in the
case of a jet suggests precession. The emission from the mm core associated
with VLA 2 is also detected; we estimate its mass to be 12-23 Msun, depending
on the contribution from ionised gas. Furthermore, the large-scale outflow has
properties intermediate between outflows from low- and high-mass young stars.
Therefore, we conclude that the IM protostar within IRAS 05373+2349 is
phenomenologically as well as quantitatively intermediate between the low- and
high-mass domains.
