finding planets with TTVs

In the tiny bit of research time available today, I spoke with Kat Deck (Caltech) and Foreman-Mackey about finding planets with large transit-timing residuals. These signals aren't precisely periodic, so some searches could miss them entirely. Deck has simple models (based on perturbation theory) for the variations, so we can in principle add only a few parameters and capture a large range in possible variations. This might make us much more sensitive to extremely important and interesting systems hiding in existing data.

The rest of the day was spent writing our NASA proposal, with the exception of lunch with Yann LeCun (facebook) and Léon Bottou (facebook) at the NYC office of facebook Research.
