The effects of a magnetic field on planetary migration in laminar and turbulent discs

We investigate the migration of low-mass planets (1, 5 and 20 M⊕) in accretion discs threaded with a magnetic field using 2D magnetohydrodynamic code in polar coordinates. We observed that, in the case of a strong azimuthal magnetic field where the plasma parameter is β ∼ 2–4, density waves at the m...
