  We have carried out near-IR/optical observations to examine star formation
toward a bright-rimmed cometary globule (BRC37) facing the exciting star(s) of
an HII region (IC1396) containing an IRAS source, which is considered to be an
intermediate-mass protostar. With slit-less spectroscopy we detected ten
H_alpha emission stars around the globule, six of which are near the tip of the
globule and are aligned along the direction to the exciting stars. There is
evidence that this alignment was originally towards an O9.5 star, but has
evolved to align towards a younger O6 star when that formed. Near-IR and
optical photometry suggests that four of these six stars are low-mass young
stellar objects (YSOs) with masses of ~0.4 M_sun. Their estimated ages of ~1
Myr indicate that they were formed at the tip in advance of the formation of
the IRAS source. Therefore, it is likely that sequential star formation has
been taking place along the direction from the exciting stars towards the IRAS
source, due to the UV impact of the exciting star(s). Interestingly, one faint,
H_alpha emission star, which is the closest to the exciting star(s), seems to
be a young brown dwarf that was formed by the UV impact in advance of the
formation of other YSOs at the tip.
