Dust environment of distant comet C/2014 A4 (SONEAR)
Abstract
The results of imaging photometric, polarimetric, and long-slit spectroscopic observations of distant comet C/2014 A4 (SONEAR) in 2015 are presented. Possible explanation of the unusual polarimetric properties of the dust in this comet is provided. Our modelling shows that the specifics of the dust in the distant comet A4 is presence of significant amount of ice and organics which likely sublimate at the smaller heliocentric distances.
