Abstract:
BVRI polarimetry of carbon stars belonging to different variability types - VX And, UU Aur, T Cae, Y CVn, U Hya, Y Hya, RY Mon, W Ori, Y Per, RT Pup, and X Vel - is presented. Though there is significant scatter, on the average, carbon stars show a flatter wavelength dependence than oxygen-rich objects. Circumstellar grain scattering appears to be the main mechanism responsible for the continuum polarization in these objects.
