This thesis develops and establishes several methods to determine the detailed geometric architecture of transiting exoplanetary systems (planets orbiting around, and periodically passing in front of, stars other than the sun) using high-precision photometric data collected by the Kepler space telescope. It highlights the measurement of stellar obliquity - the tilt of the stellar equator with respect to the planetary orbital plane(s) - and presents methods for more precise obliquity measurements in individual systems of particular interest, as well as for measurements in systems that have been out of reach of previous methods. Such information is useful for investigating the dynamical evolution of the planetary orbit, which is the key to understanding the diverse architecture of exoplanetary systems. The thesis also demonstrates a wide range of unique applications of high-precision photometric data, which expand the capability of future space-based photometry.
Kento Masuda is a NASA Sagan Postdoctoral Fellow at the Department of Astrophysical Sciences, Princeton University. He received his B.Sc., M.Sc. and Ph.D. in Physics from the University of Tokyo in March 2012, March 2014, and July 2016, respectively. He was awarded the Japan Society for Promotion of Science (JSPS) research fellowship for young scientists, and his research throughout his doctoral program was supported by the JSPS. He has also received a number of prizes and awards: the School of Science Research Award (Master) from the University of Tokyo in 2014, the JSPS Ikushi Prize in 2017, the School of Science Research Award (Ph.D.) from the University of Tokyo in 2017, and the Inoue Research Award for Young Scientists from the Inoue Foundation for Science in 2018.
