The HeI+HeII lines in both spectra of SS433 and the Wolf-Rayet star WR147, a WN8+BO5 binary system, closely match. The 2.5-12 micron continuum radiation is due to an expanding wind free-free emission in an intermediate case between optically thick and optically thin regime. A rough mass loss rate evaluation gives about 1.4 10^{-4} M_sun/yr. Results are consistent with a Wolf-Rayet-like companion to the compact object in SS433. | | Source: | arXiv, astro-ph/0112339 | | Services: | Forum | Review | PDF | Favorites | |
