A Nomenclature for Individual Exocomets

Abstract With recent observational advancements, exocomet studies have entered a new era: we have moved from an epoch where exocomets’ signatures were analysed to identify their true nature to a new epoch where individual exocomets’ detections are studied in detail to characterise the observed bodies. In this context, as with other astronomical objects such as exoplanets and minor bodies in the solar system, a nomenclature system is needed to uniquely identify any observed exocometary body. Here, after outlining the purpose of a nomenclature and its required characteristics, we review the information on exocomets that can be included in the nomenclature. Finally, we propose an exocomet nomenclature scheme to identify the individual exocomets that have been discovered or yet to be discovered. Examples of nomenclature names of a few archetypal exocomets are provided.
