Recently, the Spitzer Space Telescope discovered L1014-IRS, a mid-infraredsource with protostellar colors, toward the heretofore "starless" core L1014.We present deep near-infrared observations that show a scattered light nebulaextending from L1014-IRS. This nebula resembles those typically associated withprotostars and young stellar objects, tracing envelope cavities presumablyevacuated by an outflow. The northern lobe of the nebula has an opening angleof ~100 degrees, while the southern lobe is barely detected. Its morphologysuggests that the bipolar cavity and inferred protostellar disk is not inclinedmore than 30 degrees from an edge-on orientation. The nebula extends at least8" from the source at Ks, strongly suggesting that L1014-IRS is embedded withinL1014 at a distance of 200 pc rather than in a more distant cloud associatedwith the Perseus arm at 2.6 kpc. In this case, the apparently low luminosity ofL1014-IRS, 0.090 Lsun, is consistent with it having a substellar mass. However,if L1014-IRS is obscured by a circumstellar disk, its luminosity and inferredmass may be greater. Using near-infrared colors of background stars, weinvestigate characteristics of the L1014 molecular cloud core. We determine amass of 3.6 Msun for regions of the core with Av > 2 magnitudes. A comparisonof the radial extinction profile of L1014 with other cores suggests that L1014may be among the most centrally condensed cores known, perhaps indicative ofthe earliest stages of brown dwarf or star formation processes.Comment: Replacement includes revision to mass of core. 22 pages, 6 figures.
