Magnetic Fields in Massive Star-forming Regions (MagMaR) IV: Tracing the Magnetic Fields in the O-type protostellar system IRAS 165474247
Luis A. Zapata, Manuel Fernández-López, Patricio Sanhueza +24
The formation of the massive stars, and in particular, the role that the magnetic fields play in their early evolutionary phase is still far from being completely understood. Here,…

ALMA-IMF XIV: Free-Free Templates Derived from H and Ionized Gas Content in Fifteen Massive Protoclusters
Roberto Galván-Madrid, Daniel J. Díaz-González, Frédérique Motte +25
We use the H recombination line to create templates of the millimeter free-free emission in the ALMA-IMF continuum maps, which allows to separate it from dust emission. This m…

Badminton Birdie-Like Aerodynamic Alignment of Drifting Dust Grains by Subsonic Gaseous Flows in Protoplanetary Disks
Zhe-Yu Daniel Lin, Zhi-Yun Li, Haifeng Yang +4
Recent (sub)millimeter polarization observations of protoplanetary disks reveal toroidally aligned, effectively prolate dust grains large enough (at least ~100 m) to efficiently…
