The inner envelope and disk of L1527 revealed: Gemini l'-band-scattered light imaging.

TOBIN J.J., HARTMANN L. and LOINARD L.

Abstract (from CDS):

We present high-resolution L'-band imaging of the inner scattered light structure of Class 0 protostar L1527 IRS (IRAS 04368+2557) taken with the Gemini North telescope. The central point-source-like feature seen in Spitzer Space Telescope IRAC images is resolved in the Gemini image into a compact bipolar structure with a narrow dark lane in the center. Two scattered light lobes are extended ∼1{farcs}8 (200 AU) perpendicular to the direction of the outflow and ∼2{farcs}5 (350 AU) along the outflow axis; the narrow dark lane between the scattered light lobes is ∼0{farcs}45 (60 AU) thick. The observations are consistent with our initial modeling of a bright inner cavity separated by a dark lane due to extinction along the line of sight of the central protostar by the disk. The bright, compact scattered light might be due to complex inner structure generated by the outflow, as suggested in our first paper, or it may more likely be the upper layers of the disk forming from infalling matter.
