DOI: 10.1038/s41550-019-0991-9
Abstract: Cometary comae are generally depleted in nitrogen. The main carriers for volatile nitrogen in comets are NH 3 and HCN. It is known that ammonia readily combines with many acids, such as HCN, HNCO and… read more here.

DOI: 10.1051/0004-6361/201628963
Abstract: Context. There is an active debate about whether the properties of comets as observed today are primordial or, alternatively, if they are a result of collisional evolution or other processes. Aims. We investigate the effects… read more here.
