Abstract:
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
slitless spectroscopy we detected ten Hα 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.
Description:
Slitless grism spectroscopy and g' (482.5nm), i' (767.2nm), and wide
Hα (651nm) imaging of BRC37 were conducted on UT 2006 November 19
and V, and IC imaging was done on UT 2007 August 7 with the Wide Field
Grism Spectrograph 2 (WFGS2) mounted on the University of Hawaii 2.2m
telescope (UH88).
J- (1.25um), H- (1.63um), and Ks- (2.14um) band imaging of BRC37 was
conducted on UT 2001 August 29 with the Simultaneous three-color
InfraRed Imager for Unbiased Survey (SIRIUS) mounted on UH88.
