摘要：
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 similar to10(-2) M-. yr(-1).
