Fig. 1.


Top and center panels: first-moment maps for C18O (top; vlsr = 2.3–8.9 km s−1) and 13CO (middle; vlsr = 1.5–8.2 km s−1). Beam size is (ellipses at lower left). Contours mark the continuum emission levels of 9.4, 15.1, 20.8, 26.5, 37.8, 49.2 mJy beam−1, with a peak at 60.6 mJy beam−1. The cross symbol marks the position of the star. Bottom panel: position-velocity diagram along major axis of projected disk in 13CO; position angle 134.3°. Yellow curves represent the Keplerian profiles for a 0.5 M star.
