An ALMA search for substructure and fragmentation in starless cores in Orion B North
Samuel Fielder, Helen Kirk, Michael Dunham +1
We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 3 observations of 73 starless and protostellar cores in the Orion B North molecular cloud. We detect a total of…
Can Protostellar Outflows Set Stellar Masses?
Philip C. Myers, Michael M. Dunham, Ian W. Stephens
The opening angles of some protostellar outflows appear too narrow to match the expected core-star mass efficiency SFE = 0.3-0.5 if outflow cavity volume traces outflow mass, with…
Evolution and Kinematics of Protostellar Envelopes in the Perseus Molecular Cloud
Daniel J. Heimsoth, Ian W. Stephens, Hector G. Arce +3
We present a comprehensive analysis on the evolution of envelopes surrounding protostellar systems in the Perseus molecular cloud using data from the MASSES survey. We focus our at…
VLA and NOEMA view of the Bok Globule CB 17: the starless nature of a proposed FHSC candidate
Stephanie Spear, María José Maureira, Héctor Arce +4
We use 3mm continuum NOEMA and NH VLA observations towards the First Hydrostatic Core (FHSC) candidate CB 17 MMS to reveal the dust structure and gas properties down to 600-1,1…
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…
Detection of a Disk Surrounding the Variably Accreting Young Star HBC722
Xi Yek, Michael M. Dunham, Héctor G. Arce +5
We present new ALMA 233 GHz continuum observations of the FU Orionis Object HBC722. With these data we detect HBC722 at millimeter wavelengths for the first time, use this detectio…
