Solar cycle evolution of dipolar and pseudostreamer belts and their relation to the slow solar wind

Owens, M. J.; Crooker, N. U.; Lockwood, M.

Dipolar streamers are coronal structures formed by open solar flux converging from coronal holes of opposite polarity. Thus, the dipolar streamer belt traces the coronal foot point of the heliospheric current sheet, and it is strongly associated with the origin of slow solar wind. Pseudostreamers, on the other hand, separate converging regions of …
