Rotating disks in high-mass young stellar objects

We report on the detection of four rotating massive disks in two regions of high-mass star formation. The disks are perpendicular to known bipolar outflows and turn out to be unstable but long lived. We infer that accretion onto the embedded (proto)stars must proceed through the disks with rates of ~10E-2 Msun/yr.Comment: 11 pages, 2 figures, 1 table; accepted for publication by ApJ
