@Starguy32
Windows: After extracting from the archive, go into the folder and simply double click the systemic.jar file. It’ll take a few seconds to load.

Linux: Go into your command line, cd to the folder, and type “java -jar systemic.jar”.

Make sure you have a relatively up-to-date Java Runtime Environment on as well.

I’m sorry to add in an unrelated comment, but I just recently re-downloaded the console and have absolutely no idea how to start it up or what I need to do to run it.

There’s a paper about attempting to characterise the inner planet of Gliese 876 on the arXiv today… some limits in inclination/albedo/radius parameter space… arxiv:0910.1505

As our exoplanet statistics improve in the coming years, I believe that there shall be a menagerie of objects in this range, perhaps with distributed characteristics from mini-neptunes to super-earths. A 2D scatter distribution could be used to show the distribution of properties of these models (rock, ice…) perhaps even extended to 3D…

IIRC according to predictions of tidal theory it seems the HD 40307 planets are likely to be mini-Neptunes rather than super-Earths.

Wouldn’t an “Earth-like” density for a 5 M(e) planet be higher than 5.5, due to gravitational self-compression?

And does your limb-going apply to 90% of existing super-earths, or 90% of measured super-earths? Short period planets are both more likely to transit and more likely to lose volatiles, so I’d say that even if Corot 7b type planets are unusual, they will make up most of our detected samples for the next 10 years or more.
