title: Planets in Protoplanetary Disks: Theory and Observations

authors: Takayuki Muto

abstract: A protoplanetary disk is one of the most interesting targets of ALMA observation.  The unprecedented spatial resolution realized by ALMA will make it possible to reveal detailed structures of the disks such as spirals and gaps, which are predicted to exist in (some of) disks due to the dynamical interaction between planet and disks.  In this talk, we review some fundamentals of planet formation theory and planet-disk interaction.  Then, we discuss how such structures can be observed in protoplanetary disks.  We also present recent Subaru/HiCIAO observations, which have revealed the detailed structures of some transitional disks at NIR wavelengths.  We discuss how the synergy of Subaru and ALMA will advance our understaning of the structure of protoplanetary disks.
