| Abstract : | Star-forming regions (SFRs) are ideal candidates to understand different mechanisms involved in star formation. SFRs may harbor bright-rimmed clouds (BRCs), which are remnant molecular clouds possibly undergoing triggered star formation due to radiative feedback from the high-mass stars. To investigate the role of high-mass stars on the star-formation activity in BRCs, we studied a nearby region, BRC 44 (distance ~ 1 kpc), which is part of HII region sh2-145. To obtain a census of young stellar objects (YSOs) in this region, we exploited infrared (IR) data from the 2MASS, TIRCAM-II mounted on the 3.6m DOT, Spitzer-IRAC, and MIPS. A total of ~ 40 YSOs were identified through the Spitzer-IRAC and MIPS observations. Using 2MASS/ TIRCAM-II near-IR (NIR) data, an additional number of YSOs is recovered.
To constrain the evolutionary status and mass of these YSOs, we used the NIR color-magnitude diagram, which revealed that these are low-mass stars at a very young age. The spatial distribution and the kinematics of the YSOs indicate that these may have been formed due to the high-mass stars in the adjacent HII region. |
