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 might be available for them upon request. (The total number of on-site participants is limited to less than or equal to 90, which may be changed without notice depending on the Covid-19 situation. If the registered number exceeds this limit, we will prioritize presenters, young scientist, and earlier registered persons.)

Registration page is opened here.

Slots of contribution talks are available. Please provide the title and abstract of your talk in the registration form. We will inform participants of the talk selection by Oct 8th. For the abstract format, we will recommend you to use the following template.

Travel information to Japan:
Please check the border measure applied to your situation.

All the non-Japanese citizens are currently required to obtain visas, even if you are from visa-exempt countries. This is due to the covid-19 restriction. We will help you with the paperwork if you need a visa. The government announced the plan to discontinue this policy in the near future, but the exact date of the policy change has not been decided. We will keep updated with the latest information.

Currently you don’t need to quarantine if you are from “blue” countries. (Most of you probably fall in here.)

You do not need to show a pre-departure negative PCR test result to enter Japan anymore if you are vaccinated for 3 times with vaccines approved by the Japanese government.

If you are not vaccinated for 3 times or your vaccine is one that is not recognized by the Japanese government, you need to show a negative PCR test result 72 hours prior to the boarding from the origin of your trip. See below for the requirement.
