Abstract: We compare the CO 2-1 observations against previously taken CO 4-3observations and analyze the spatial distribution of young stellar objectsYSOs within the cloud using the Spitzer IRAC observations of the 30 Doraduscomplex. Both peaks of CO 2-1 and 4-3 emitting clouds coincide with the densestregion of the filaments where multiple shells are colliding. We find that theYSOs are clustered in the southern ridge of the warm and dense molecular gasclouds traced by CO J=4-3, indicating a filamentary structure of star formationthroughout the 30 Doradus. We also find that some of Class I YSOs candidateswhich are likely to be associated with a high-velocity component of CO 4-3emitting clouds are present. This is a bona fide place where the triggered starformation had happened and newly formed stars may have produced such ahigh-velocity outflow interacting with the surrounding molecular cloudmaterial.
