| Abstract: |
Hinode observations have provided a new view of outflows from the
Sun. These have been focussed in particular on flows emanating from
the edges of active regions. These flows are long lasting and seem to
exist to some extent in every active region. The flows measured have
values ranging between tens of km s-1 and 200 km s-1. Various
explanations have been put forward to explain these flows including
reconnection, waves, and compression. Outflows have also been observed
in coronal holes and this review will discuss those as well as the
interaction of coronal holes with active regions. Although outflowing
plasma has been observed in all regions of the Sun from quiet Sun to
active regions, it is not clear how much of this plasma contributes to
the solar wind. I will discuss various attempts to prove that the
outflowing plasma forms part of the solar wind. |
