Scientific Rationale:
覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧
      Ever since the first discovery of an extrasolar planet orbiting around a Sun-like star in 1995, more than 1900 exoplanets (+ about 4000 candidates) have been observed so far. A number of ongoing and future surveys do and will keep increasing the population of observed exoplanets. In addition, the advent of ALMA with significantly upgraded capabilities has recently enabled the unprecedented high resolution observations at (sub)mm wavelengths. For instance, the long-baseline science verification campaign reveals multiple gaps in a circumstellar disk around HL Tau, a young (< Myrs) YSO, which may be a signature of planet formation. These revolutionary observations are currently triggering the rapid progress on the understanding of the formation and evolution of planets, which may occasionally require paradigm shifts. It is fascinating that planet formation can serve as a fundamental platform to unite these observations and related sciences.

Aims and Scopes:
覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧覧
In a golden era of planetary sciences, it would be of essential importance to
(1) examine both theoretically and observationally the current understanding of how planetary systems are born out of their natal circumstellar disks and of how the systems evolve with time,
(2) summarize unresolved issues and open questions, and
(3) attempt to develop new ideas/visions to derive a better understanding of planet formation.
This workshop will be designed to cover the above points.

Specifically, this workshop will stimulate the following activities;
- review the current status of both theory and observations
- discuss the latest results of both theoretical and observational work
- summarize key questions that will/should be addressed in the near future
- trigger new collaborative work among theorists and observers
- enhance interactions between theorists and observers
- encourage involvement of young people including postdocs and students
- provide young students with plenty of chance to interact both with active researchers in the world and with key scientists in Japan

Sunday, May 31, Day 0:  Welcome party

Monday, June 1, Day 1: Current view of planet formation
Aim: to make sure that everyone is on the same page, and to pose key questions -
     is our understanding of star and planet formation right??

- disk formation in the context of star formation
- statistical properties of exoplanets
- ALMA observation of HL Tau

Tuesday, June 2, Day 2: Formation and evolution of circumstellar disks
Aim: to make a connection between Classes I and II

- disk formation in the context of star formation
- properties of protoplanetary disks (dust/gas, chemistry, asymmetry etc)
- evolution of protoplanetary disks (full disks to transition disks, dust traps etc)

Wednesday, June 3, Day 3: Formation and evolution of planets
Aim: to make a connection between disks and planets and between formation and evolution of planets

- growth of dust grains/formation of planetesimals
- planet formation (CA vs GI, migration)
- evolution of planets (planetary dynamics, atmospheres)

Thursday, June 4, Day 4: Toward the future
Aim: to summarize the future missions and key questions that can be answered in the near future

- the future mission
- Astrobiology
