Do HgMn (peculiar A type) stars really possess global magnetic fields? See, for example, this paper by Hubrig et al. from 2012.
The magnetic field activity in a star can be very chaotic and my question is are they somehow related?
Is it observable what is the north and what is the south pole of magnetic fields of stars and black holes?
The question is related to this about Are there collected data about the direction of rotation of black holes and the direction of the magnetic field?. Perhaps it is observable for pulsars?
Are there collected data about the direction of rotation of black holes and the direction of the magnetic field?
Is there a relation between the direction of rotation of black holes or neutron stars and the magnetic dipole moment of BH or neutron stars? BTW, are there different directions of this two parameters ...
