Transiting planet
We are sometimes faced with the situation where one planet is detected by its photometric transit and we are interested in doing RV follow-up to (i) confirm it, (ii) measure its mass, and (iii) detect additional planets in the system.
kima can now help with the analysis of the RV data in these cases.
By default, the Keplerian model we use assumes the same priors for the orbital parameters of all the planets in the system. But when doing RV follow-up, there is extra information about one of the planets: its orbital period, and some phase in the orbit, usually the time of mid-transit. We can use this information to set tighter priors for one specific planet.
Notes
- currently, only one known transiting planet can be considered
(this limitation is fairly easy to address if needed) - this feature is available only in the
bgplanet
branch, it is not backward-compatible, and will not be added to the master branch for now
