Research Abstract

Following the recent discovery of exoplanets and development of detailedobservations of protoplanetary disks, we have studied evolution of dust and gas in the disks, which will turn into Terrestrial and Jovian planets, its environmental effects, and its effects on observational properties. Comparison between our model calculations with brand-new observations suggests existence of small dust grains and turbulent mixing in the disk surfaces. Also, our model calculations suggest that molecular line observations with the Atacama large millimeter/submillimeter array (ALAM) will revealvarious gas dispersal mechanisms from disks.
