Magnetic fields and massive star formation

Q Zhang, K Qiu, JM Girart, YW Tang… - The Astrophysical …, 2014 - iopscience.iop.org
ABSTRACT Massive stars (M> 8 M☉) typically form in parsec-scale molecular clumps that
collapse and fragment, leading to the birth of a cluster of stellar objects. We investigate the …
