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 ...

Searching for Molecular Jets from High-mass Protostars
The Astrophysical Journal Supplement Series, 2023 We report Very Large Array observations in the Q band toward 10 ionized jet candidates to search for SiO emission, a well-known shocked gas tracer. We detected 7 mm continuum counterparts toward 90% of the jet candidates. In most cases, the jet candidate

CORINOS. II. JWST-MIRI Detection of Warm Molecular Gas from an Embedded, Disk-bearing Protostar [PDF]
The Astrophysical JournalWe 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.

Frontiers in Astronomy and Space Sciences, 2021 The huge variety of planetary systems discovered in recent decades likely depends on the early history of their formation. In this contribution, we introduce the FAUST Large Program which focuses specifically on the early history of solar-like protostars

The Astrophysical Journal Supplement Series, 2023 We present a Spitzer/Herschel focused survey of the Aquila molecular clouds ( d ∼ 436 pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500 ParSecs) census of nearby protostars.

Early Planet Formation in Embedded Disks (eDisk). I. Overview of the Program and First Results
The Astrophysical Journal, 2023 We present an overview of the Large Program, “Early Planet Formation in Embedded Disks (eDisk),” conducted with the Atacama Large Millimeter/submillimeter Array (ALMA).

The Rate, Amplitude, and Duration of Outbursts from Class 0 Protostars in Orion
The Astrophysical Journal Letters, 2022 At least half of a protostar’s mass is accreted in the Class 0 phase, when the central protostar is deeply embedded in a dense, infalling envelope. We present the first systematic search for outbursts from Class 0 protostars in the Orion clouds.

300: An ACA 870 μm Continuum Survey of Orion Protostars and Their Evolution
The Astrophysical Journal, 2023 We present an 870 μ m continuum survey of 300 protostars from the Herschel Orion Protostar Survey using the Atacama Compact Array (ACA). These data measure protostellar flux densities on envelope scales ≤8000 au (20″) and resolve the structure of ...

Magnetic Effects Promote Supermassive Star Formation in Metal-enriched Atomic-cooling Halos
The Astrophysical Journal, 2023 Intermediate-mass black holes (with ≥10 ^5 M _⊙ ) are promising candidates for the origin of supermassive black holes (with ∼10 ^9 M _⊙ ) in the early universe (redshift z ∼ 6).
