The 590 days long term periodicity of the microquasar GRS 1915+105
arXiv:astro-ph/0305106 · doi:10.1086/376683
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.
