Vertical propagation of waves in the solar atmosphere. I. Observations of phase delays

摘要: The Sacramento Peak Observatory Tower Vacuum Telescope, echelle spectrograph, and diode array were used to simultaneously measure velocities intensities in three spectral lines the continuum. According our contribution function calculations, these wavelengths are formed at heights from low photosphere chromosphere. phase of intensity velocity oscillations between various heights, relations one height determined as a frequency range 0--11.1 mHz. found be predominantly evanescent nature for frequencies less than 4 mHz propagating upward higher frequencies, with approaching sound speed approximately 6 We calculated mechanical flux observed waves two atmospheric by an integration frequency, we show that chromosphere propagated power is centered MHz but still much too small heat overlying atmosphere.
