Abstract: The solar analogy is generally accepted for interpretation of stellar activity, yet coronal and chromospheric data of active stars often show very non-solar-like characteristics. Rather than beginning with the Sun and extrapolating backwards, we begin with the pre-main sequence stars and extrapolate forward in time. Among the youngest active stars, above the main sequence, there is strong evidence for quasi-dipolar magnetic fields. Time-series spectroscopy of chromospheres of diverse active stars shows characteristics consistent with matter trapped in a magnetic canopy. Radio observations suggest highly extended radio coronae. We present new and published data in support of a new paradigm for stellar activity based on the decay of large-scale organized magnetic fields.
