Progress in the studies on a relic solar magnetic field
Abstract
It is really possible that the Sun possesses a relic magnetic field of the pre-main sequence epoch in its radiative core. Due to a stably stratified fluid and an extremely high electrical conductivity in the solar interior, a relic solar magnetic field can survive for a very long time. A relic field can help us to explain many asymmetries in solar activities, such as the north-south asymmetries of solar magnetic activities, active longitudes and holes, low-latitude coronal holes, Maunder minimum, etc. In addition it can affect the distribution and evolution of solar surface magnetic field by changing the boundary conditions of solar dynamo. This paper focuses on the introduction of recent progress and issues in observations and theories of relic solar magnetic field. Some unresolved problems and highlights are also discussed.
