Multiwavelength studies of MHD waves in the solar chromosphere: An overview of recent results
The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool
photosphere and the intensely heated transition region and corona. Compressible and …

Spatial distribution of oscillations in faculae
NI Kobanov, VA Pulyaev - Solar Physics, 2011 - Springer
We find that oscillations of the LOS velocity in Hα vary within facula regions. The power
spectra show that the contributions of low-frequency modes (1.2–2 mHz) increase at the …
