Scientific paper

The authors have discovered remarkable structure in the wavelength dependence of the optical linear polarization of R Aquarii over the spectral range 4030 Å to 8500 Å which manifests itself as an increase in the degree of linear polarization across the strong titanium oxide absorption bands and a decrease in emission lines. The direction of vibration of the polarization also changes across both types of spectral features. The authors suggest that the overall polarization structure results from a combination of two or more polarigenic mechanisms and that the detailed structure in the molecular absorption bands can be explained by the existence of photospheric hotspots (convection cells) on the cool stellar component.
