cds-question@unistra.frx-ray-sourcesx-ray-binary-starsWe present a comprehensive X-ray study of four years of pointed RXTE observations of GRS 1915+105 in the {chi}-state. We interpret the behavior of the hard power law tail spectrum as coming from inverse Compton scattering of soft disk photons on a thermally dominated hybrid corona above the accretion disk. GRS 1915+105 shows a strong, variable reflection amplitude. As in other BHC and in Seyfert galaxies, a correlation between the power law slope and the reflection was found. Also, the radio fluxes at 2.25GHz and 15GHz correlate with the power law slope, thus revealing a connection between the outflowing matter and the comptonizing region in the {chi}-states.2003A&A...397..711Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/397/711CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/62 : Photoelectric absorption cross-sections (Balucinska-Church+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/397/711https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/397/711http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/397/711https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/397/711https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/397/711http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/397/711GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-raydefaultJ/A+A/397/711/table2Fitting resultsE_xiUpper error of xistat.errorintrecnoRecord number assigned by the VizieR team.
