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 CARMA-NRO Orion Survey: Protostellar Outflows, Energetics, and Filamentary Alignment

Jesse R. Feddersen, Héctor G. Arce, Shuo Kong +7

We identify 45 protostellar outflows in CO maps of the Orion A giant molecular cloud from the CARMA-NRO Orion survey. Our sample includes 11 newly detected outflows. We measure the…

The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars. A Statistical Characterization of Class 0 and I Protostellar Disks

John J. Tobin, Patrick Sheehan, S. Thomas Megeath +33

We have conducted a survey of 328 protostars in the Orion molecular clouds with ALMA at 0.87 mm at a resolution of 0.1" (40 au), including observations with the VLA at 9 mm t…
