PublicationAn attempt to compare the differential rotation of the Ca/plus/-network with that of the photospheric plasma
Results of almost simultaneous observations of the differential rotation of the Ca(plus) chromosphere and the photospheric plasma are reported. The observations...

PublicationAnalysis of the solar low-l p-mode asymmetries using wavelets
It is presently widely accepted that the solar low l p modes show asymmetric profiles when their power spectrum is analysed and that the fact of fitting...
