Date & Time: 2025/May/27 17:00-18:00, Venue: Zoom TV Conference System and Kyushu University. This is an informal seminar on the formation of stars and planets. We welcome anyone interested in the subject.
Abstract:
The gas composing the interstellar medium (ISM) is inherited from old stars and, at the same time, feeds into new stars and, eventually, new planets. Understanding the chemistry in the processes of star and planet formation is a crucial step in revealing not only the chemical but also the physical processes that drive these phenomena. Stars form in dense cloud cores that can be studied through the emission of cold dust and molecules. Dense cores have a relatively high column density of dust, which effectively blocks the ambient radiation in the optical and ultraviolet regions of the electromagnetic spectrum. Thanks to this shielding, molecules can survive, and molecular complexity can be built. Molecular emission in such dense cores is how we can observe the process of star formation and study the chemical evolution from clouds to stars and planets. Because of the interconnection between the chemistry and the physics of dense cores, identification of molecules can be used to study the dynamics of the star-formation process, as well as the chemical budget that will finally be inherited by the forming planets. In my talk, I will give a general introduction to Astrochemistry through its three pillars: laboratory spectroscopy, astronomical observations, and modelling. I will also present the research done in my group and highlight some recent results linking interstellar clouds to planets.
