Abstract: We present results of polarimetric observations of Saturn’s moon Rhea carried out from March 23, 2012 — May 2, 2014 in WR spectral band (550—750 nm). We used 2.6-m telescope equipped with a one-channel photoelectric photometer-polarimeter (Crimean Astrophysical Observatory). The phase-angle dependence of linear polarization of Rhea was obtained using the results of our observations. Results obtained are discussed in terms of existing models of light scattering by regolith surfaces. |
