Serpens Cluster B and VV Ser Observed With High Spatial Resolution at 70, 160, and 350um

Abstract

We report on diffraction-limited observations in the far-infrared and sub- millimeter of the Cluster B region of Serpens (G3-G6 Cluster) and of the Herbig Be star to the south, VV Ser. The observations were made with the Spitzer MIPS instrument in fine-scale mode at 70um, in normal mapping mode at 160um (VV Ser only), and the CSO SHARC-II camera at 350um (Cluster B only). We use these data to define the spectral energy distributions of the tightly grouped members of Cluster B, many of whose SEDs peak in the far-infrared. We compare our results to those of the c2d survey of Serpens and to published models for the far-infrared emission from VV Ser. We find that values of Lbol and Tbol calculated with our new photometry show only modest changes from previous values, and that most source SED classifications remain unchanged.
