Planet formation processes depend on the evolution of protoplanetary disks. It is therefore important to use a realistic model of disk evolution in studies of planet formation. In previous studies, however, a classical disk model with power-law distributions is used. In this talk, I will present recent studies on planet formation that consider a new model of disk evolution including the effects of disk winds and photoevaporation. In particular, I will discuss the formation of super-Earths in close-in orbits and examine whether observed features can be reproduced by N-body simulations. I will also present results of simulations of giant planet formation that use the latest disk evolution model. In addition, I will mention future observations of exoplanets and discuss research directions of planet formation.
Dr. Masahiro Ogihara earned his Ph.D. from Tokyo Institute of Technology in 2011. During the Ph.D. course, he was selected as a JSPS Research Fellow for Doctoral Course Students. Then he was a JSPS Research Fellow for Postdocs at Nagoya University during 2011-2014 and a JSPS Research Fellow for Research Abroad at Observatoire de la Cote d'Azur during 2014-2016. Since 2016 he has been an NAOJ fellow at National Astronomical Observatory of Japan. His research interests include formation and dynamics of planets and satellites, evolution of protoplanetary disks, and exoplanet observation.
