Measurements of dust reveal the magnetic field in a protoplanetary disk
Nature Astronomy, Published online: 05 February 2025; doi:10.1038/s41550-024-02455-w
Observations of polarized thermal emission from dust grains in the protoplanetary disk around the HD 142527 protostar suggest that in part of the disk the polarization is caused by the magnetic field. The strength and structure of this magnetic field are deduced from these observations using a modelling approach.
