Synchrotron emission from circumstellar disks around massive stars | | Yu. A. Shchekinov

11 Feb 2004 | | Journal: | Astron.Astrophys. 418 (2004) 1045-1050 | | Subject: | astro-ph | | Affiliation: | Rostov State U.), A. M. Sobolev (Ural State U. | | Abstract: | 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 $L_ssim 10^{-5}lsun$ 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. | | Source: | arXiv, astro-ph/0402251 | | Services: | Forum | Review | PDF | Favorites | |
