TRADES: a new software to derive orbital parameters from observed Transit Times and Radial Velocities. Revisiting Kepler-11 and Kepler-9
http://arxiv.org/abs/1408.2844

They use the software to constrain Kepler-11 and Kepler-9, finding lower planet masses than previously reported in these systems. This might be some fun to play with when the software is released.

Nice to see that the paper confirms the results of Dreizler and Ofir (which remain unpublished in a refereed journal) for Kepler-9.
