Abstract:
Although close-in Jovian planets have been studied intensively for over three decades, their formation and evolutionary histories remain incompletely understood. Thanks to a series of space missions—especially TESS—the number of known close-in Jovian planets orbiting bright stars has grown rapidly. This expansion enables a wealth of photometric and spectroscopic observations that provide new constraints on their dynamical evolution. In this talk, I will explore the dynamical histories of close-in Jovian planets through the lens of recent observations, focusing on several key topics: planetary multiplicity, stellar obliquity, and mutual inclination.
Biography:
Dr. Xian-Yu Wang is a Sullivan Prize Postdoctoral Fellow at Indiana University. His research leverages advanced photometric and spectroscopic observational techniques, along with big data analysis, to investigate exoplanet demographics and system architectures, enhancing our understanding of exoplanet formation and evolution. Before joining Indiana University, he earned his Ph.D. in Astrophysics from the National Astronomical Observatories of China (NAOC) in January 2023. As a principal investigator, he has been awarded more than 40 nights of telescope time on facilities such as NEID/WIYN, HARPS-N/TNG, LCOGT, and others. His work has frequently been featured by AAS Nova and selected for presentation at major conferences, including EXOPLANET V. More information can be found on his website: wangxianyu.com.
