CSN invites contributions from the astronomical and planetary science communities, including abstracts of papers accepted for publication in refereed journals, thesis abstracts, timely notes on particular comets, conference announcements, job announcements, or other relevant and brief scientific communications. Relevant topics include observational, theoretical, and laboratory work concerning comets, but also may include studies of associated phenomena, such as Centaurs, asteroid-comet transition objects, debris disks, and protoplanetary disks.
