Abstract
In this chapter, I present the work I have done towards characterising three planetary systems: CoRoT-7, Kepler-78 and Kepler-10. CoRoT-7 is an active star host to a small hot Neptune and the first Earth-size exoplanet ever discovered. Kepler-78 is an active star orbited by an extremely close-in hot, Earth-mass planet. Kepler-10 is old and quiet, and harbours two transiting planets—one a super-Earth, the other a rocky world the size of Neptune whose discovery challenges our theories of planet formation. All three of these systems were first discovered via the transit method, by the CoRoT and Kepler space missions. They were followed up with HARPS, HARPS-N and HIRES in order to obtain a precise mass determination of the planets present in these systems.
This chapter uses material from, and is based on, Haywood et al. (2014), MNRAS, 443, 2517 and my own contributions to Dumusque et al. (2014), ApJ, 789, 154, and Grunblatt et al. (2015), ApJ, 808, 127.
