About this document
Sunspot Oscillations and Their Dynamics by VRINDA JOSHI is a document available to read on EtoBox.
Oscillations in sunspots occur due to concentrated magnetic fields that form barriers to convection. There are two types of characteristic oscillations observed in sunspots - 5-minute oscillations in the photosphere and 3-minute oscillations in the chromosphere. Waves above sunspots also behave differently in the photosphere, chromosphere, and corona, with varying amplitudes and periods. The umbra shows reduced power oscillations similar to the quiet sun, while the penumbra displays 5-minute oscillations in
