mercury6.2jh	This is my variant of John Chambers' MERCURY code, which is an N-body integrator that is used to study the orbital evolution of planetary systems. The code provided here is a slightly tweaked version of John's code, and includes additional forces that can drive planet migration or orbit decay due to a drag force. Also included are several IDL routines that I use to read an analyze the output; see the README for details. A tarfile containing everything, as well as the individual files, are available. John's original MERCURY code can also be found at his website.
ddisk	Version 4.0 of ddisk.pro, which is my IDL script that calculates the time-evolution of a circumstellar debris disk; see my 2010 ApJ paper on the topic, titled 'Diagnosing Circumstellar Debris Disks'.
epi_int	epi_int is my N-body integrator for evolving gravitating planatery rings, written in IDL.
