The Astrophysical Journal, 2010 We explore the origin of a population of distant companions (~1000 - 5000 AU) to Class I protostellar sources recently found by Connelley and co-workers, who noted that the companion fraction diminished as the sources evolved.

CO in Protostars (COPS): $Herschel$-SPIRE Spectroscopy of Embedded Protostars [PDF]
The Astrophysical Journal, 2018 We present full spectral scans from 200-670$\mu$m of 26 Class 0+I protostellar sources, obtained with $Herschel$-SPIRE, as part of the "COPS-SPIRE" Open Time program, complementary to the DIGIT and WISH Key programs.

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).

Herschel-PACS imaging of protostars in the HH 1–2 outflow complex [PDF]
, 2010 We present 70 and 160 μm Herschel science demonstration images of a field in the Orion A molecular cloud that contains the prototypical Herbig-Haro objects HH 1 and 2, obtained with the Photodetector Array Camera and Spectrometer (PACS).

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.

Interacting jets from binary protostars [PDF]
Astronomy & Astrophysics, 2007 We investigate potential models that could explain why multiple proto-stellar systems predominantly show single jets. During their formation, stars most frequently produce energetic outflows and jets. However, binary jets have only been observed in a very small number of systems. We model numerically 3D binary jets for various outflow parameters.
