Synchrotron emission from circumstellar disks around massive stars

AbstractWe 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 $L_ssim 10^{-5}lsun$ for a central star with $dot M=10^{-6}msun$ yr$^{-1}$, comparable with the value observed around the TW object in the W3(OH) region.
