Close-in Exoplanets in the K2 era
Roberto Sanchis-Ojeda



Since its launch in 2009, the Kepler telescope has revolutionized the field of exoplanets. After staring at approximately 200,000 stars for four years, the Kepler telescope has discovered more than 4000 planet candidates, of which more than 1000 have been confirmed as bona fide planets, corresponding to almost 60% of all confirmed exoplanets to date. The discovery of the first earth-size transiting planets in the Habitable Zone of main sequence stars and the first circumbinary planets are two of the great discoveries of Kepler. After the main mission ended in 2013 when two of the four reaction wheels failed, a two-wheel mission concept was born, K2. In this new mission, the telescope stares at a different field in the ecliptic plane every three months. This new setting makes the telescope particularly attune to the detection of hundreds of close-in exoplanets orbiting host stars that are typically a few magnitudes brighter on average than the Kepler host stars. In this talk I will review some of the key Kepler discoveries about close-in exoplanets, and how K2 has the potential to improve on these discoveries, including some early scientific results from the first three months of K2 observations like the discovery of the first disintegrating planet orbiting an M-dwarf or the first K2 pair of planets near a first order resonance.
