Changes in Solar Oscillation Frequencies during the Current Activity Maximum: Analysis and Interpretation
Changes in Solar Oscillation Frequencies during the Current Activity Maximum: Analysis and Interpretation
Abstract We describe systematic changes in the centroid frequencies and the splitting coefficients as found using data from MDI on board SOHO, covering cycle 23. The data allow us to construct a seismic map of the evolving solar activity - covering all latitudes. At lower latitudes, the temporal evolution closely …
