Abstract Found near the edges of HII regions, bright-rimmed clouds (BRCs) are thought to be home to triggered star formation. Using Spitzer Space Telescope archival data, we investigated two BRCs, BRC 27 and BRC 34, to search for previously known and new candidate additional young stellar objects (YSOs). BRC 27 is located in the molecular cloud Canis Majoris R1, a known site of star formation. BRC 34 has a variety of features worthy of deeper examination: dark nebulae, molecular clouds, emission stars, and IR sources. Our team used archival Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS), combined with 2-Micron All-Sky Survey (2MASS) data. We investigated the infrared properties of previously known YSOs and used infrared colors to identify additional new candidate YSOs in these regions. This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by NASA Astrophysics Data Program and Archive Outreach funds.
