Abstract:
We carried out a deep near-infrared survey of a bright-rimmed
molecular cloud, BRC 14 (IC 1848A). The 10sigma limiting
magnitude of the survey is 17.7mag at the K-band. Seventy-four
sources are classified as young stellar object (YSO) candidates based
on a near-infrared color-color diagram. The faintest YSO candidates
may have masses on the order of tenths of the solar mass, assuming an
age of 1Myr. We examined three values as indicators of star formation:
fraction of the YSO candidates, extinctions of all sources, and
near-infrared excesses of the YSO candidates. All indicators increase
from outside of the rim to the center of the molecular cloud, which
suggests that the formation of the low-mass stars in the BRC 14 region
proceeds from outside to the center of the cloud.
Description:
The observations were carried out in 2001 August 26 with the
Simultaneous-3 color InfraRed Imager for Unbiased Survey (SIRIUS)
mounted on the 2.2m telescope of University of Hawaii.
