CORINOS. II. JWST-MIRI Detection of Warm Molecular Gas from an Embedded, Disk-bearing Protostar

The Astrophysical Journal
We present James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) observations of warm CO and H _2 O gas in emission toward the low-mass protostar IRAS 15398-3359, observed as part of the CORINOS program.

An Embedded Disk (eDisk) in the IceAge: Investigating the Jet and Outflow from Ced 110 IRS4

The Astronomical Journal
We 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 ...

The ALMA-QUARKS Survey: Investigating Thermal Feedback of Massive Protostars in Hot Molecular Cores

The Astrophysical Journal Supplement Series
We identify a sample of 83 spatially resolved hot molecular cores (HMCs) in the Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures (QUARKS) survey, aiming at investigating thermal feedback from ...

Structure and Evolution of Intermediate-mass Protostars [PDF]

, 2007
総合研究大学院大学博士（理学）In the last two decades, the development of millimeters interferometers has enabled us to establish a standard scenario of sun-like (M*～1 MΘ ) star formation. However, details of formation and　evolution of more massive stars (≥2 M&

First Detection of Circular Polarization in Radio Continuum Toward a Massive Protostar

The Astrophysical Journal Letters
Polarization 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 ...

The Evolution of Far-infrared CO Emission from Protostars [PDF]

, 2016
We investigate the evolution of far-IR CO emission from protostars observed with Herschel/PACS for 50 sources from the combined sample of HOPS and DIGIT Herschel key programs. From the uniformly sampled spectral energy distributions, whose peaks are well

Probing the Ubiquity of Complex Ices in Protostars with JWST: The First Systematic Quantification of Weak Ice Bands between 6.8 and 7.9 μm

The Astrophysical Journal Letters
Complex organic molecules (COMs) are the key to understanding the chemical evolution from simple interstellar molecules to potential prebiotic material. Although COMs have been extensively studied in the gas phase toward protostars, their counterparts in
