Abstract: Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary observations can therefore provide direct insight into the chemistry that occurred during their… read more here.

DOI: 10.1038/s41550-020-1095-2
Abstract: Interstellar comets offer direct samples of volatiles from distant protoplanetary disks. 2I/Borisov is the first notably active interstellar comet discovered in our Solar System 1 . Comets are condensed samples of the gas, ice and… read more here.

DOI: 10.1093/mnras/staa4022
Abstract: We present results from multiband photometry of the interstellar comet 2I/Borisov (C/2019 Q4). The observations were carried out in the two months before its perihelion passage. The UBVri photometric data obtained for comet 2I were… read more here.

DOI: 10.1093/mnrasl/slaf095
Abstract: The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and composition, which may alter as it is heated in the coming… read more here.
