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…
Research on the Interstellar Medium and Star Formation in the Galaxy: An Indian Perspective
Bhaswati Mookerjea, Maheswar G., Kinsuk Acharyya +24
Although the star formation process has been studied for decades, many important aspects of the physics involved remain unsolved. Recent advancement of instrumentation in the infra…
The first Ka-band (26.1-35 GHz) blind line survey towards Orion KL
Xunchuan Liu, Tie Liu, Zhiqiang Shen +30
We conducted a Ka-band (26.1--35 GHz) line survey towards Orion KL using the TianMa 65-m Radio Telescope (TMRT). It is the first blind line survey in the Ka band, and achieves a se…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Discovery of an extremely dense and compact object embedded in the prestellar core G208.68-19.92-N2
Naomi Hirano, Dipen Sahu, Sheng-Yaun Liu +19
The internal structure of the prestellar core G208.68-19.02-N2 (G208-N2) in the Orion Molecular Cloud 3 (OMC-3) region has been studied with the Atacama Large Millimeter/submillime…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): The Warm-Envelope Origin of Hot Corinos
Shih-Ying Hsu, Sheng-Yuan Liu, Doug Johnstone +24
Hot corinos are of great interest due to their richness in interstellar complex organic molecules (COMs) and the consequent potential prebiotic connection to solar-like planetary s…
Episodic Accretion in Protostars -- An ALMA Survey of Molecular Jets in the Orion Molecular Cloud
Somnath Dutta, Chin-Fei Lee, Doug Johnstone +20
Protostellar outflows and jets are almost ubiquitous characteristics during the mass accretion phase, and encode the history of stellar accretion, complex-organic molecule (COM) fo…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): A forming quadruple system with continuum `ribbons' and intricate outflows
Qiu-yi Luo, Tie Liu, Aaron T. Lee +31
One of the most poorly understood aspects of low-mass star formation is how multiple-star systems are formed. Here we present the results of Atacama Large Millimeter/submillimeter…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): How do dense core properties affect the multiplicity of protostars?
Qiuyi Luo, Tie Liu, Kenichi Tatematsu +34
During the transition phase from a prestellar to a protostellar cloud core, one or several protostars can form within a single gas core. The detailed physical processes of this tra…
