Context. Dust polarization observations of the massive protocluster G31.41+0.31 carried out at ~1'' (~3750 au) resolution with the SMA at 870 microm have revealed one of the clearest examples to date of an hourglass-shaped magnetic field…

When dust particles are immersed in a plasma, and the power that sustains a plasma is terminated, the charge of dust particles will change in the early afterglow, as electrons and ions gradually diminish in number. The possibility of…
