Pair Annihilation and Radio Emission from Nova Muscae | D.C. Hannikainen

; | Date: |
5 Aug 2002 | Subject: | astro-ph | Affiliation: | 1,2) and C.R. Kaiser ( Observatory, University of Helsinki, Finland, Department of Physics & Astronomy, University of Southampton, UK | Abstract: | In the hard X-ray spectra of some X-ray binaries line features around 500 keV are detected. We interpret these as arising from pair annihilation in relativistic outflows leading to a significant Doppler shift of the frequencies of the lines. We show that a small fraction of pairs escaping the annihilation region may give rise to the radio synchrotron emission observed in Nova Muscae 1991. | Source: | arXiv, astro-ph/0208086 | Services: | Forum | Review | PDF | Favorites |
