Density distributions, magnetic field structures, and fragmentation in high-mass star formation★

Context . The fragmentation of high-mass star-forming regions depends on a variety of physical parameters, including density, the magnetic field, and turbulent gas properties. Aims . We evaluate the importance of the density and magnetic field structures in relation to the fragmentation properties during high-mass star formation. Methods . Observing the large parsec-scale Stokes I millimeter dust continuum emission with the IRAM 30 m …
