Rotating filament in Orion B: Do cores inherit their angular momentum from their parent filament?
Cheng-Han Hsieh, Héctor G. Arce, Diego Mardones +2
Angular momentum is one of the most important physical quantities that govern star formation. The initial angular momentum of a core may be responsible for its fragmentation and ca…
The CARMA-NRO Orion Survey: Filament Formation via Collision-Induced Magnetic Reconnection -- The Stick in Orion A
Shuo Kong, Volker Ossenkopf-Okada, Héctor G. Arce +13
A unique filament is identified in the {\it Herschel} maps of the Orion A giant molecular cloud. The filament, which, we name the Stick, is ruler-straight and at an early evolution…
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…
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…
Relative Alignment between Dense Molecular Cores and Ambient Magnetic Field: The Synergy of Numerical Models and Observations
Che-Yu Chen, Erica A. Behrens, Jasmin E. Washington +26
The role played by magnetic field during star formation is an important topic in astrophysics. We investigate the correlation between the orientation of star-forming cores (as defi…
