AbstractMeasuring the stellar obliquity of multi-transiting planetary systems helps to distinguish whether a single planet's orbit was tilted or if the entire protoplanetary disk was misaligned. Here we present the stellar obliquity measurements of three multi-transiting systems at different ages (young, adolescent, mature). Combining our observations and dynamical analysis, we find the transiting planets in these three systems are aligned and coplanar. In conjunction with past observations, it is suggested that multi-transiting systems tend to be aligned and coplanar.
About the SpeakerHuanyu Teng is currently a postdoctoral researcher and an East Asian Core Observatories Association (EACOA) Fellow, collaborating with three institutions: the National Astronomical Observatories, Chinese Academy of Sciences (NAOC), the Korea Astronomy and Space Science Institute (KASI), and the National Astronomical Observatory of Japan (NAOJ). He received his PhD in 2023 from Tokyo Institute of Technology (now known as Institute of Science Tokyo). His primary research focuses on the detection of exoplanets using the radial velocity (RV) method, which includes blind surveys, transit follow-ups, and joint analysis with astrometry. He also works on characterizing planetary architectures, including stellar obliquity, orbital mutual inclination, and other related parameters.
