Article Synopsis
- The study focuses on the linear polarization of light from distant comets C/2010 S1, C/2010 R1, C/2011 KP36, C/2012 J1, C/2013 V4, and C/2014 A4, observed from 2011 to 2016 using a 6-m telescope in Russia.
- The negative polarization measured was found to be significantly higher than that of comets near the Sun, indicating distinct dust properties in these distant comets.
- Computer simulations using different model particle types demonstrated good agreement with the observed data, suggesting that the dust composition likely includes mixtures of water-ice and silicate or organic particles.
