Mutual relationship of oscillations in the frequency range 3.6 mHz to 22 mHz in the solar chromosphere
High frequency acoustic oscillations were suggested as the source of mechanical heating in the chromosphere. In this work the radial component of the oscillations in the frequency interval 3 mHz to 22 mHz are investigated. The observations were performed using "D spectrometry on the Fe I neutra...

| Summary: | High frequency acoustic oscillations were suggested as the source of mechanical heating in the chromosphere. In this work the radial component of the oscillations in the frequency interval 3 mHz to 22 mHz are investigated. The observations were performed using "D spectrometry on the Fe I neutral spectral line at 543:45 nm. The high frequency oscillations of different frequencies appear to be associated with different spatial scales. It seems that different sources produce high and low frequency acoustic oscillations. |
