Aperture polarimetry of selected comets at CrAO
In the period from 2012 to 2017 polarimetric observations of 9 comets were carried out at CrAO. Based on the results of observations, the polarization phase dependencies (PPD) of comets were obtained. Moreover, observation data were compared with the synthetic PPD of comets constructed according to the polarimetric database of comets. Taking into account the photometric, spectral and polarimetric characteristics of the observed comets, their classification was carried out, namely, the assignment of each comet to groups with a high or low degree of polarization at large phase angles.
