Scientific paper

Spectropolarimetric and spectrophotometric data on the emission line object SS433 were obtained to determine whether the emission features are due to velocity or magnetic Zeeman shifts. The spectrophotometry suggests that the variable-wavelength emission features of SS433 detected by Margon et al. (1979) are induced by the simultaneous presence of material with a substantial redshift and a substantial blueshift. The polarimetric measurements rule out a magnetic interpretation of the SS433 features. Dynamical implications of the hydrogen and neutral helium lines undergoing very large velocity (and perhaps gravitational) shifts in SS433 are also examined.
