[41.15] A ``Starless" Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope

C.H. Young (University of Texas at Austin), Cores to Disks Spitzer Legacy Team

We present observations of L1014, a dense core in the Cygnus region previously thought to be starless. Our data span wavelengths from 2.17 to 1200 micrometers, including the infrared bands of IRAC and MIPS on the Spitzer Space Telescope. We propose a model for this source that includes a cold envelope, heated externally by the interstellar radiation field, with a very low-luminosity internal source that is traced by the short wavelength region of the core's spectral energy distribution. The low luminosity of this object suggests a very low mass object. The alternative intepretation, that a more luminous protostar lies directly behind L1014, at much greater distance, is less likely. If L1014 is at all representative, other ``starless" cores may turn out to harbor central sources.
