タイトル: Dust Size Growth and Settling in Protoplanetary Disks: 
          Effects on Observational Properties






  It is believed that in protoplanetary disks dust particles are
sticking together and settling towards the disk midplane as the first
step of planet formation. Observationally, protoplanetary disks have
been detected through thermal and scattered emission of dust grains
as well as transition line emission of molecular gas. The dust
evolution in the disks is expected to affect on the physical and
chemical disk structure, and then the observational
properties of the disks. I have been working on modeling the physical
structure of protoplanetary disks, and effects of the dust evolution
on observations of the dust and gas in the disks.
 In this talk I will summarize what I have worked on at Kobe
University. The contents of the talk will be


  - Dust size growth and settling in a protoplanetary disk

  - Effects of dust evolution on chemical structure of the disks

  - Effects on molecular hydrogen emission from the disks

  - Effects of photoevaporating flow and dust evolution on 

  thermal dust emission from the disks
