Scientific paper

High-resolution (about 3.5 arcsec) maps centered on the embedded infrared source, L1551 IRS 5, have been made in the J = 1-0 transition of C(0-18), using the Millimeter Wave Interferometer of the Owens Valley Radio Observatory. An elongated concentration of gas, with its long axis about 700 AU in radius, and of mass about 0.1 solar mass, has been detected. The orientation is perpendicular to the direction of outflow of the high-velocity molecular gas, suggesting a casual relationship. The observations are consistent with this gas being bound to the star, and the overall properties are fairly similar to those of the HL Tau system. It is not yet possible to establish whether the rotation curve shows Keplerian motion for the gas.
