Prestellar cores represent the initial conditions of star formation, but heavy molecules such as CO are strongly depleted in their cold, dense interiors, limiting the ability to pr…
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…

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…
Density Structure of Centrally Concentrated Prestellar Cores from Multi-scale Observations
Dipen Sahu, Sheng-Yuan Liu, Doug Johnstone +23
Starless cores represent the initial stage of evolution toward (proto)star formation, and a subset of them, known as prestellar cores, with high density (~ 10^6 cm^-3 or higher) an…
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…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Deriving Inclination Angle and Velocity of the Protostellar Jets from their SiO Knots
