Investigating Sulfur Chemistry in the HD 163296 disk
Rong Ma, Donghui Quan, Yan Zhou +6
Sulfur chemistry in the formation process of low-mass stars and planets remains poorly understood. The protoplanetary disks (PPDs) are the birthplace of planets and its distinctive…

Chemical differences among collapsing low-mass protostellar cores
Jingfei Sun, Xiaohu Li, Fujun Du +3
Organic features lead to two distinct types of Class 0/I low-mass protostars: hot corino sources, and warm carbon-chain chemistry (WCCC) sources. Some observations suggest that the…
