Evershed effect

Webphotospheric layers, the Evershed effect (Evershed 1909).At high spatial resolution, the Evershed effect was found to be structured into thin, elongated radial flow filaments in which the material flows intermittently at a speed of about 1–6kms−1 along those elevated flow channels from inside the sunspot to WebDec 4, 1997 · The Evershed effect 1 —a wavelength shift and profile asymmetry in the spectral lines observed from the outer regions of sunspots (the penumbra)—has …

John Evershed British astronomer Britannica

The Evershed effect, named after the British astronomer John Evershed, is the radial flow of gas across the photospheric surface of the penumbra of sunspots from the inner border with the umbra towards the outer edge. The speed varies from around 1 km/s at the border between the umbra and the penumbra to a maximum of around double this in the middle of the penumbra and falls off to zero at the outer e… WebDiscovered in 1909, the Evershed effect represents strong mass outflows in sunspot penumbra, where the magnetic field of sunspots is filamentary and almost … personal finance software india https://tfcconstruction.net
