How the chemical complexity evolves during the process leading to the formation of a Sun and its planetary system? Is the chemical richness of a Solar-like planetary system, at least partially, inherited from the earliest stages or is there a complete chemical reset? A powerful way to answering these questions is by comparing the chemical content in young protostars and primitive bodies of the Solar System, using astrochemistry as a tool. Yet, to do so, we need to fully understand the processes that govern the chemical evolution of a molecular cloud into a young planetary system.
The goal of the conference is to gather together the actors of this intrinsically interdisciplinary endeavor: instrumentalists, astronomers, chemists and modelers. The recent progresses in the four areas make the time ripe for these communities to join and ride this scientific wave.
The conference aims to review:
The new results from the powerful observing facilities, such as the IRAM-NOEMA, ALMA and VLA interferometers, and the chemical composition during the youngest phases of Solar-like planetary systems, from prestellar cores to protoplanetary disks, with particular emphasis on the interstellar complex organic molecules;
The recent progresses due to the enhancement of high-performance computing facilities combined with efficient quantum chemistry algorithms, which allow for the in-silico simulation of many chemical processes occurring both in gas-phase and at grain surfaces;
The latest laboratory experiments which have provided new insights on the possible processes occurring in the interstellar conditions;
The new generation astrochemical models as well as the innovative tools to interpret the astronomical observations that have seen the light in the last few years;
The most recent results on the chemical composition of the small bodies of the Solar System.
This will naturally pave the way for discussing the future developments in front of us.
The meeting will consist of invited reviews, invited and contributed talks, and posters, in 4 sessions:
I. Interstellar ices,
II. Molecular complexity,
III. Molecular fractionation,
IV. Cometary ices.
The 4 sessions will cover the astronomical observations and modeling, as well as laboratory experiments and theoretical computations.
Confirmed invited speakers: Alexander Tielens (NL), Piero Ugliengo (IT), Eleonora Bianchi (DE), Fabrice Duvernay (FR), Eva Wirström (SE), Steve Charnley (USA), Oba Yashiro (JP), Stephanie Cazaux (NL).
The posters should have the usual format A0 (or smaller if you want). We have multiple railings ( each are 170cm*121cm) to hang the posters with clips. The posters will be shown the whole week.
The invited talks are 30mn long+10mn questions and the contributed talks are 15mn long+5mn questions.
It is always preferable to send the organizers the pdf of your talk in advance so that we use only 1 laptop and do not lose time to change laptop. We advise you to do that and send your pdf presentation in advance to the organisers (aco-conference2023 at sciencesconf.org). The laptop has keynote and powerpoint installed, but a good old fashioned pdf is, as you know, alway better.
