But on-line options are prepared for participants from abroad. This conference will celebrate the career of Satoshi Yamamoto, who has made enormous contributions to establish the concept of "chemical evolution" in astrochemistry. Invited speakers will be announced soon. With best regards, Organizing committee Nami Sakai(chair, RIKEN), Shogo Tachibana(The Univ. of Tokyo), Yuri Aikawa(The Univ. of Tokyo), Yuji Nakano(Rikkyo Univ.), Hiroshi Imada(RIKEN), Naoki Watanabe(Hokkaido Univ.), Toshiyuki Takayanagi(Saitama Univ.), Hajime Tanuma (Tokyo Metropolitan Univ.), and Yousoo Kim(RIKEN) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 29 Nov.- 2 Dec. 2022, Tokyo Venue: The University of Tokyo, Koshiba-Hall +++1st circuler+++ Next Generation Astrochemistry: Reconstruction of the Science Based on Fundamental Molecular Processes Planet formation is a natural consequence of the star formation process, and there is an incredible variety of planetary systems, which are significantly different from the Solar System. Recent observations have revealed chemistry in planet-forming regions. Various complex organic molecules are found in protoplanetary- disk forming regions, and their abundances vary significantly among objects. This indicates that the Solar System may not have been common in terms of its initial chemistry, which invokes the discussion on the rarity of our existence. Progress of the Solar System exploration, including the recent successful return of the Hayabusa2 spacecraft, makes it possible to analyze pristine Solar System materials directly. The combination of such analysis with high-sensitivity observations of planet-forming regions will tell us the chemical origin of our Solar System and how common or rare it is in the universe. However, to tackle these questions, we have to revisit fundamental astrochemical processes. In the past decades, the astrochemical studies focused on chemistry under extremely low temperature and density conditions, where only barrier-less exothermic reactions proceed efficiently. During the planetary system formation, on the other hand, the physical condition changes dynamically resulting in dynamic interactions of molecules between gas and dust(ice) surface. Investigation of such physical and chemical processes is crucial to understand the formation of complex organic molecules and the chemical variety of planet-forming regions. Through this conference we will facilitate interdisciplinary studies among the fields of molecular science, planetary science, and astronomy. This conference will celebrate the career of Satoshi Yamamoto, who has made enormous contributions to establish the concept of "chemical evolution" in astrochemistry. Students and young researchers are encouraged to attend and interact with all participants, and to present their works. Although there is a limitation, financial help will be available for them upon request. (The total number of on-site participants is limited to less than or equal to 80, which may be changed without notice depending on the Covid-19 situation). If the registered number exceeds this limit, we will prioritize presenters.) Registration page will be opened in mid September. ********************************************************************* 分子科学会速報 発行：分子科学会 http://www.molsci.jp/index.html 速報投稿規程等は下記をご覧下さい。 http://www.molsci.jp/bulletin.html ********************************************************************* 高速・高分解能MCAとSDDX線検出器用アンプは、お任せください。 (株)ラボラトリ・イクイップメント・コーポレーション http://www.labo-eq.co.jp Mail:sales@labo-eq.co.jp Tel:029-850-3333 *********************************************************************
