TitleClosing the solar cycle: emerging active regions
AuthorsHannah Schunker
AbstractThe emergence of magnetic field from the interior of the Sun generates a poloidal magnetic field from rising toroidal magnetic field. How sunspots and active regions emerge is a crucial, but poorly understood aspect of the solar dynamo. Only since the advent of the SDO/HMI monitoring campaign has it been possible to capture the emergence process of hundreds of active regions in observations of the magnetic field, Doppler velocity and intensity continuum. By measuring the average motion of the polarities, surface velocities and pattern of convection, it is clear that convection plays an important role in the emergence of magnetic field on the Sun.
