Sunspots: Evershed Effect
Abstract
The Evershed Effect is an observational effect in the penumbra of SUNSPOTS consisting in displacements of the spectral line profiles towards either shorter wavelengths (that is, blueshifts) in the zones closest to the Sun's disk center or larger wavelengths (that is, redshifts) in those zones closest to the solar limb. Since the first detection in 1909, this effect was correctly interpreted by it...
