We use Spitzer Infrared Spectrograph (IRS) mid-infrared spectra, high-resolution Combined Array for Research in Millimeter-wave Astronomy (CARMA) 230GHz continuum imaging, and two-dimensional radiative transfer models to constrain the envelope structure, as well as the size and mass of the circumprotostellar disk in Serpens FIRS 1. The primary envelope parameters (centrifugal radius, outer radius, outflow opening angle, and inclination) are well constrained by the spectral energy distribution (SED), including Spitzer IRAC and MIPS photometry, IRS spectra, and 1.1mm Bolocam photometry. These together with the excellent uv-coverage (4.5-500k{lambda}) of multiple antenna configurations with CARMA allow for a robust separation of the envelope and a resolved disk. The SED of Serpens FIRS 1 is best fit by an envelope with the density profile of a rotating, collapsing spheroid with an inner (centrifugal) radius of approximately 600AU, and the millimeter data by a large resolved disk with M_disk_~1.0M_{sun}_ and R_disk_~300AU.2009ApJ...707..103Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/707/103CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/692/973 : Protostars in Perseus, Serpens and Ophiuchus (Enoch+, 2009)J/ApJ/691/672 : Spectrocopy of YSOs in Serpens molecular cloud (Oliveira+J/ApJ/684/1240 : Prestellar cores in Perseus, Serpens and Ophiuchus (Enoch+,J/ApJ/663/1149 : Spitzer survey of Serpens YSO population (Harvey+, 2007)J/ApJ/669/493 : Spitzer/Chandra YSOs in Serpens cloud core (Winston+, 2007)J/A+A/463/275 : Chandra obs. of Serpens star-forming region (Giardino+, 2007)J/A+A/421/623 : ISOCAM survey of YSOs in Serpens Cloud Core (Kaas+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/707/103https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/707/103http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/707/103https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/707/103https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/707/103http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/707/103GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap1.5239960011708423e-22 1.5239960011708423e-22InfraredRadiodefaultJ/ApJ/707/103/table2CARMA 230GHz visibilitiese_FluxUncertainty in FluxJystat.error;phot.fluxfloatrecnoRecord number assigned by the VizieR team.
