Alignment of dense molecular core morphology and velocity gradients with ambient magnetic fields
A. Pandhi, R. K. Friesen, L. Fissel +15
Studies of dense core morphologies and their orientations with respect to gas flows and the local magnetic field have been limited to only a small sample of cores with spectroscopi…
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…
Models of Rotating Infall for the B335 Protostar
Neal J. Evans, Yao-Lun Yang, Joel D. Green +7
Models of the protostellar source, B335, are developed using axisymmetric three-dimensional models to resolve conflicts found in one-dimensional models. The models are constrained…
Role of Filamentary Structures in the Formation of Two Dense Cores, L1544 and L694-2
Shinyoung Kim, Chang Won Lee, Mario Tafalla +5
We present mapping results of two prestellar cores, L1544 and L694-2, embedded in filamentary clouds in CO (3-2), CO (3-2), CO (3-2), HCO (4-3), and H$^{13…
Virial Clumps in Central Molecular Zone Clouds
Philip C. Myers, H Perry Hatchfield, Cara Battersby
CMZoom survey observations with the Submillimeter Array are analyzed to describe the virial equilibrium (VE) and star-forming potential of 755 clumps in 22 clouds in the Central Mo…
The Magnetic Field in the Milky Way Filamentary Bone G47
Ian W. Stephens, Philip C. Myers, Catherine Zucker +21
Star formation primarily occurs in filaments where magnetic fields are expected to be dynamically important. The largest and densest filaments trace spiral structure within galaxie…
