7 May 2003 | | Journal: | Astrophys.J. 590 (2003) L37-L40 | | Subject: | astro-ph | | Abstract: | We report on the discovery of a 590 days long term periodicity in the hard X-ray component of the microquasar grs found from a comprehensive study of more than four years of {it RXTE} observations. The periodicity is also observed in the hard X-ray flux observed by BATSE, and in the radio flux as seen with the {it Green Bank Interferometer} and the {it Ryle Telescope}. We discuss various possible explanations, including the precession of a radiation induced warped accretion disk. | | Source: | arXiv, astro-ph/0305106 | | Services: | Forum | Review | PDF | Favorites | |
