Detecting phasecurves in the K2 data

Hajj Sleiman, Jana (Notre Dame University-Louaize., 2019-02)

Exoplanets are planets orbiting stars other than our Sun. During their motion around their star, due to gravitational eﬀects, and due to the planet’s thermal and reﬂective radiation, small variations in the lightcurve could be detected (Esteves et al. 2015). Phasecurves are small-scale variations in planetary ﬂux that arise from an exoplanet’s motion around its host star. If detected, the phasecurve can lead to determining the planet’s mass, its albedo, and it can give us an idea about its atmosphere. In this work we aim to detect these variations in the data from the K2 mission. To do this we ...
Planet-metallicity correlation for Kepler’s giant planets

Nehme, Mireille Hanna (Notre Dame University-Louaize, 2014-07)

This study is part of a newly growing science in exoplanet characteristics. We present an initial attempt to investigate the relationship between the eclipse depth of giant exoplanets and the metallicity of their host stars to show the best eclipse depth-metallicity trend. This will help us to better understand the conditions that lead to giant planets formation, which helps to postulate about the formation of our Solar System and more generally the planet formation theories. Previous studies have shown that stars with giant planets tend to have higher metallicities than stars without giant ...
