Disks and Outflows in the Intermediate-mass Star Forming Region NGC 2071 IR
Yu Cheng, John J. Tobin, Yao-Lun Yang +13
We present ALMA band 6/7 (1.3 mm/0.87 mm) and VLA Ka band (9 mm) observations toward NGC 2071 IR, an intermediate-mass star forming region. We characterize the continuum and associ…
The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars V. A Characterization of Protostellar Multiplicity
John J. Tobin, Stella S. R. Offner, Kaitlin M. Kratter +16
We characterize protostellar multiplicity in the Orion molecular clouds using ALMA 0.87~mm and VLA 9~mm continuum surveys toward 328 protostars. These observations are sensitive to…
Detection of Substructures in Young Transition Disk WL 17
Hannah Gulick, Sarah Sadavoy, Luca Matra +2
WL 17 is a young transition disk in the Ophiuchus L1688 molecular cloud complex. Even though WL 17 is among the brightest disks in L1688 and massive enough to expect dust self-scat…
Kinematic Analysis of a Protostellar Multiple System: Measuring the Protostar Masses and Assessing Gravitational Instability in the Disks of L1448 IRS3B and L1448 IRS3A
Nickalas K. Reynolds, John J. Tobin, Patrick D. Sheehan +7
We present new Atacama Large Millimeter/submillimeter Array (ALMA) observations towards a compact (230~au separation) triple protostar system, L1448 IRS3B, at 879~\micron with \con…
The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars IV. Unveiling the Embedded Intermediate-Mass Protostar and Disk within OMC2-FIR3/HOPS-370
John J. Tobin, Patrick Sheehan, Nickalas Reynolds +13
We present ALMA (0.87~mm and 1.3~mm) and VLA (9~mm) observations toward the candidate intermediate-mass protostar OMC2-FIR3 (HOPS-370; L~314~L) at 0.1" (40~…
Astro2020 Science White Paper: Measuring Protostar Masses: The Key to Protostellar Evolution
John J. Tobin, Stella Offner, Patrick Sheehan +10
Knowledge of protostellar evolution has been revolutionized with the advent of surveys at near-infrared to submillimeter wavelengths. This has enabled the bolometric luminosities a…
