报告摘要：Chemical inventories of planet formation are established in stellar nurseries, where ices accumulate on dust grains before stars and disks emerge. ALMA observations of protostars suggest that a substantial fraction of this interstellar ice inventory is inherited by planet-forming disks. Yet, meteoritic records reveal that some solids undergo significant thermal processing, reshaping the material available for planet formation. Understanding the balance between inheritance and processing therefore requires a joint view of the gas and ice reservoirs. In this talk, I will present recent JWST results from molecular clouds, protostars, and planet-forming disks that trace the evolving chemical inventory and element partitioning during the earliest stages of planet formation. I will then touch upon ongoing efforts to connect these findings with an ALMA large program investigating the formation and evolution of complex organic molecules.

主讲人简介：Dr. Daniel Harsono works on the early stages of star and planet formation. He earned his Ph.D. from Leiden University in the Netherlands in 2014, where he studied disk formation around low-mass stars. He was an EACOA fellow between 2019 and 2021. In recent years, he has focused on analyzing JWST observations of atomic and molecular lines toward protostars and protostellar disks.
