[...] In the second and third phases of the systemic project, we’ll be studying synthetic data sets that have been produced using our own algorithms. “Systemic Jr.” will launch at the beginning of September, and will contain 100 synthetic data sets, four of which will be special challenge systems. The Systemic Challenge, sponsored by Sky and Telescope will be explained in more detail, and will be available at a link on their website. The challenge systems will be released on September 3, 10, 17, and 24, along with a specific set of contest rules. The first person to crack each of these systems will recieve a paperback edition of the Millennium Star Atlas (a $149.95 value). In order to prepare for the contests, go ahead and download a copy of the systemic console, and work through tutorials one, two, and three. A full technical manual for the console is in the works, and will be ready for download quite soon. [...]

[...] Although the media glare focused almost entirely on the dramatic extraction of the inner planet from the radial velocities (to replicate this feat, try systemic console tutorial #3), Eugenio’s paper contains a number of other very significant, albeit subtler results. Perhaps the most important of these is the fact that the orbital inclination of the GJ 876 outer-planet orbits can be determined to a very high accuracy from the analysis of the radial velocity data. There are no other extrasolar planetary systems for which this is possible, and it seems unlikely that this situation will change for at least a decade. [...]

[...] Users familiar with console tutorial #3 will have noticed that the self-consistent 2-planet fit to the system is presented as a fait accompli. We are currently implementing an “epoch” slider for the console which will greatly smooth the transition from Keplerian to Newtonian fits for interacting systems, but amazingly, it turns out to be possible to obtain a competitive 3-planet fit to the Rivera et al (2005) GJ 876 data set using only the current version of the systemic console. This post gives the details, and gets a bit technical, so if you are interested in following it closely, we suggest that you first work through tutorials 1, 2, and 3. [...]

[...] The project will officially start in early 2006. In the meantime, we have released a beta version of the systemic console, along with three tutorials (1, 2, and 3). [...]

[...] Tutorial #3 tackles the tough problem of multiple-planet fitting in the presence of planet-planet interactions, and uses the console to explore the remarkable, recently published Gl 876 data set. [...]
