IRAS observations of young stellar objects in the Corona Australis dark cloud
The young stellar object (YSO) population associated with the dark cloudcomplex in Corona Australis is studied by synthesizing IRAS data withnewly obtained near-IR and mid-IR photometry and previously publishedoptical/IR data. Twenty-four YSOs in the Cr A complex are identified.The observed range of spectral energy distribution shapes and bolometricluminosities are consistent with those observed in other dark clouds.The duration and efficiency of star formation are found to be similar tothe Rho Ophiuchi IR cluster. The low number of YSOs compared to otherdark clouds is understood by a reevaluation of the molecular mass of theR Cr A cloud which shows it to be much less massive than previouslyassumed.
