Speaker Choi, Yunhee (Radio Science Group, KASI)
Abstract The purpose of this work is to study the physical and chemical evolution of high-mass star formation using H2O, which is a sensitive tracer of conditions in star-forming regions. Herschel/HIFI allows us to observe velocity-resolved multiple rotational transitions of H2O including the ground-state levels, and also its isotopologues. In addition, photodissociation regions (PDRs) are targeted to investigate the distribution of water and its chemistry, especially the ortho-to-para ratio (OPR) of H2O in PDRs.
Remarks This talk will be given in Korean.
