Abstract:
I present an overview of some observations of young and active
solar-like stars with non-solar-like characteristics.
I ask whether the solar analogy can be extrapolated
to explain very active stars without violating simple geometrical constraints.
Is a young and active star merely an extreme version of today's Sun, with the
same atmospheric structures but with filling factors reaching (or exceeding)
unity? In light of evidence for large scale quasi-dipolar magnetic topologies
on the young and restless stars, maybe it is time to rethink our paradigms.
