Survey of Complex Organic Molecules in Starless and Prestellar Cores in the Perseus Molecular Cloud
Cold (∼10 K) and dense (∼105 cm−3) cores of gas and dust within molecular clouds, known as starless and dynamically evolved prestellar cores, are the birthplaces of low-mass (M ≤ […]

Formation Of Carbonyl Sulfide (OCS) via SH Radicals In Interstellar CO-rich Ice Under Dense Cloud Conditions
Carbonyl sulfide (OCS) is widely observed in the gas phase towards star-forming regions and was the first of the only two sulfur-bearing species detected in interstellar ices so far. However, […]

Chemistry Across Dust and Gas Gaps in Protoplanetary Disks: Modelling the Co-spatial Molecular Rings in the HD 100546 Disk
High-resolution observations show that typically both the dust and the gas in nearby extended protoplanetary disks are structured, possibly related to radial and azimuthal variations in the disk density and/or […]
