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 …
A Monopolar Jet from Protostar HOPS 10: Evidence for Asymmetric Magnetized Launching
Somnath Dutta
A fundamental challenge in star formation is understanding how a protostar accretes mass from its circumstellar disk while removing excess angular momentum. Protostellar jets are w…
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…
Jets in Low-Mass Protostars
Somnath Dutta
Jets and outflows are key components of low-mass star formation, regulating accretion and shaping the surrounding molecular clouds. These flows, traced by molecular species at (sub…
Molecular Jets from an Evolved Protostar: Insights from JWST-ALMA Synergy
Somnath Dutta
The combination of ALMA submillimeter and JWST/MIRI mid-infrared observations offers a transformative view of protostellar jets and outflows by probing cold and warm gas components…
ALMASOP. A Rotating Feature Rich in Complex Organic Molecules in a Protostellar Core
Shih-Ying Hsu, Chin-Fei Lee, Doug Johnstone +25
Interstellar complex organic molecules (COMs) in solar-like young stellar objects (YSOs), particularly within protostellar disks, are of significant interest due to their potential…
