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…
ALMA observations of envelopes around first hydrostatic core candidates
Maria Jose Maureira, Hector G. Arce, Michael M. Dunham +4
We present ALMA 3 mm molecular line and continuum observations with a resolution of ~3.5" towards five first hydrostatic core (FHSC) candidates (L1451-mm, Per-bolo 58, Per-bolo 45,…
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…
A Study of Millimeter Variability in FUor Objects
John Wendeborn, Catherine C. Espaillat, Enrique Macias +6
FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption,…
Star-Gas Surface Density Correlations in Twelve Nearby Molecular Clouds I: Data Collection and Star-Sampled Analysis
Riwaj Pokhrel, Robert A. Gutermuth, Sarah K. Betti +15
We explore the relation between the stellar mass surface density and the mass surface density of molecular hydrogen gas in twelve nearby molecular clouds that are located at 1.5…
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…
