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 for a central star with yr-1, comparable with the value observed around the TW object in the W3(OH) region.
Key words: accretion, accretion disks / stars: circumstellar matter / acceleration of particles
