Irradiation-Dominated Magnetized Protoplanetary Disks: Disk Structures and Planet Formation

Abstract: Revealing the structure and evolution of protoplanetary disks is essential for understanding planet formation pathways. Although magnetic fields significantly shape disk structures, their exact influence remains uncertain, constraining our understanding of planet formation. In this talk, I present our recent work on magnetized protoplanetary disks. First, we conduct a state-of-the-art global MHD simulation incorporating full non-ideal MHD effects and radiative transfer. In particular, we focus on the temperature structures and gas dynamics controlled by stellar irradiation. Next, we examine the long-term evolution of the global temperature distribution, emphasizing how MHD effects influence disk temperatures. I present how the updating of the temperature model may impact the orbital migration and water content of super-Earths, in comparison with recent exoplanet observations.
