Abstract:
We report the results of a millimeter interferometric survey of compact
3 mm continuum sources in the inner 5.5'x5.5' region
of the Serpens core. We detect 32 discrete sources above 4.0 mJy/beam,
21 of which are new detections at millimeter wavelengths. By comparing
our data with published infrared surveys, we estimate that 26 sources are
probably protostellar condensations and derive their mass assuming optically
thin thermal emission from dust grains. The mass spectrum of the clumps,
dN/dM~M^(-2.1), is consistent with the stellar initial mass function,
supporting the idea that the stellar masses in young clusters are determined
by the fragmentation of turbulent cloud cores.
