Seeking a Postdoctoral Researcher or Research Associate (W24057)

Laboratory

Star and Planet Formation Laboratory
RIKEN Cluster for Pioneering Research
(Laboratory head: Nami Sakai)

Research Field

Star formation is one of the most fundamental structure-formation processes in the universe. By use of the state-of-the-art radio telescopes including ALMA, we are investigating chemical evolution along star and planet formation. At the same time, we are also revealing its formation mechanism by full use of physicochemical tools. When and how is a disk structure formed around a protostar, how is it evolved into a protoplanetary disk and eventually to a planetary system, and how does chemical composition change along them? Those are essential questions deeply related to the origin of the Solar system and even the life. Toward full understanding of the chemical evolution, we are also conducting related laboratory experiments; spectroscopy of molecules in astronomical interests in the millimeter and submillimeter regimes.
