NED Abstract

Copyright by Royal Astronomical Society. 2006MNRAS.372.1602W A new interpretation of the remarkable X-ray spectrum of the symbiotic star CH Cyg Peter J. Wheatley and Timothy R. Kallman Abstract. We have re-analysed the ASCA X-ray spectrum of the bright symbiotic star CH Cyg, which exhibits apparently distinct hard and soft X-ray components. Our analysis demonstrates that the soft X-ray emission can be interpreted as scattering of the hard X-ray component in a photoionized medium surrounding the white dwarf. This is in contrast to previous analyses in which the soft X-ray emission was fitted separately and assumed to arise independently of the hard X-ray component. We note the striking similarity between the X-ray spectra of CH Cyg and Seyfert 2 galaxies, which are also believed to exhibit scattering in a photoionized medium. Key words: accretion, accretion discs, binaries: symbiotic, stars: individual: CH Cyg, white dwarfs, stars: winds, outflows, X-rays: binaries
