Observations of DNC and DCO toward the -shaped Filament and Starless Cores in the Orion Molecular Clouds

Ken'ichi Tatematsu, Atsushi Nishimura, Hideo Ogawa +25

Although the deuterium fraction is known to be a powerful evolutionary tracer, its variation within individual molecular cloud cores is still poorly understood. The northern …

MAJORS II: HCO+& HCN Abundances in W40

René Plume, David J. Eden, Malcolm J. Currie +34

We present observations of HCN and HCO J = in the central region of the W40 massive star forming region. The observations were taken as part of a p…

Backlighting young stellar objects in the Central Molecular Zone: an ensemble-averaged abundance structure of methanol ices

Yewon Kang, Deokkeun An, Jiwon Han +5

The Central Molecular Zone (CMZ) contains a substantial reservoir of dense molecular gas, where numerous young stellar objects (YSOs) and dense cloud cores have been identified. Ho…

ALMASOP: Inner-Envelope Structures of Protostars Driving Nascent Jets

Somnath Dutta, Chin-Fei Lee, Naomi Hirano +15

Protostellar jets provide valuable insight into the evolutionary stage and formation history of star-forming cores in their earliest phases. We investigated the inner envelope stru…
