First Detection of CH3OD in Prestellar Cores
The Astrophysical JournalThe isotopic ratios of deuterated methanol derived around protostars are commonly used to infer the physical conditions under which they formed in the earlier prestellar stage.

An Embedded Disk (eDisk) in the IceAge: Investigating the Jet and Outflow from Ced 110 IRS4
The Astronomical JournalWe present a comprehensive study of the large-scale structure, jet and outflow morphology, and kinematics of the Class 0/I protostellar binary Ced 110 IRS4, using JWST NIRCam (F150W and F410M) and MIRI MRS observations from the JWST ERC program IceAge ...

First Detection of Circular Polarization in Radio Continuum Toward a Massive Protostar
The Astrophysical Journal LettersPolarization measurements provide strong constraints on magnetic fields in star-forming systems. While magnetic field estimates of a few kG have been obtained near the surfaces of low-mass protostars, there are no analogous measurements in the immediate ...

Identification of Hot Gas around Low-mass Protostars
The Astrophysical JournalThe low carbon content of Earth and primitive meteorites compared to the Sun and interstellar grains suggests that carbon-rich grains were destroyed in the inner few astronomical units of the young solar system.

ALMASOP: Inner-envelope Structures of Protostars Driving Nascent Jets
The Astrophysical JournalProtostellar jets provide valuable insight into the evolutionary stage and formation history of star-forming cores in their earliest phases. We investigated the inner envelope structures of three extremely young protostars, selected for having the ...
