Abstract

Observations of exoplanets have made significant progress over the past decade, and we have obtained a variety of information about them. At the same time, theoretical studies on the origin of exoplanets have also progressed. Planet formation processes depend on the evolution of protoplanetary disks. Therefore, it is important to use a realistic model of disk evolution in planet-formation simulations. In this talk, I will present recent studies on formation of exoplanets that consider a new model of disk evolution, including the effects of disk winds and photoevaporation.

Biography

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.
