Since I do the same in other forums where I participate, from time to time I'll post links to current papers and/or science journal tables of contents related to planetary sciences. Below are a couple of papers in press with the Journal of Geophysical Research-Planets. Note: The Mellon and Phillips preprint may be restricted for those with
online subscriptions (i.e., may require a username and password).
