Abstract

K2 has continued the legacy of Kepler by finding smaller exoplanets with its comparable precision photometry. Due to failure of two reaction wheels, K2 requires additional data processing caused by drifting of the targets. In this work, I discuss the discovery of triple planetary system GJ 9827 that our team at Wesleyan found in K2 campaign 12 data, and our pipeline that was used for the discovery. These triple planetary systems have some of the best mass estimates for super-earths, as well as have among the highest expected signal to noise ratio for atmospheric characterization. Additionally in my thesis, I systematically searched for the phase curves for all the K2 planets, and was able to detect phase curves in a few of the systems. I use the phase curve to better constrain the orbital parameters whenever possible. I also explore the prospects of finding Trojans objects in K2 data, and conclude K2 is not precise enough for such detections.
