Living with an active star
Abstract
The Sun's dynamic magnetic field drives space weather throughout the heliosphere, and impacts planetary atmospheres by subtle effects linked by complex pathways. The magnetic field in the solar atmosphere is continually adjusting to the large-scale flows on the surface, to flux emergence and subduction through that surface, and to the forces that open up the field into interplanetary space. Whereas many of the processes involved in the evolution of the field continue to be elusive in their details, the International Living With a Star program requires us to take a systems engineering point of view, that is, to assemble our piece-wise knowledge into a comprehensive model. In this talk, I plan to show early results of this effort, with emphasis on the surface magnetic field, on coronal heating and irradiance, and on the corona-heliosphere connection.
