摘要：
We argue that the interaction of stellar wind with the surface of a circumstellar accretion (or protoplanetary) disk can result in the acceleration of relativistic electrons in an external layer of the disk, and produce synchrotron radiation. Conservative estimates give a total synchrotron luminosity L(s)similar to10(-5) L-circle dot for a central star with (M)over dot=10(-6) M-circle dot yr(-1), comparable with the value observed around the TW object in the W3(OH) region.
