Research Interests

My current research interests focus primarily on modeling various interactions between hot Jupiters and their parent stars. Hot Jupiters are the Jupiter-mass planets located within ~ 0.1 AU from their parent stars. As a result, these exotic giant planets are intensely illuminated, and magnetically as well as tidally interact with their parent stars. I have been studying thermal tides that drive atmospheric circulation on hot Jupiters. I am also modeling stellar and planetary atmospheres to study the possibility of planet-induced emissions and planet transits as a result of both stellar and planetary MHD winds. In addition, I have been engaging in the calculation that the star-planet interactions can destruct a young hot Jupiter in a proto-planetary disk, therefore explaining the mass distribution of hot Jupiters observed today. Furthermore, the presence of a cavity in a protoplanetary disk as revealed by dust continuum emissions has at times been postulated as a potential signopst of an embedded gas giant planet. I recently have started a research to investigate how to dynamically indentify a massive planet in a protoplanetary disk.
