YOUNG STELLAR OBJECTS IN THE MASSIVE STAR-FORMING REGION W49.
TLDR
In this study, a combination of IRAC, MIPS, Two Micron All Sky Survey, and UKIRT Deep Infrared Sky Survey data was used to identify and classify the young stellar objects (YSOs) and concluded that W49 has the richest population, with seven subclusters of YSOs. Expand
