Popis: | We present evidence supporting wave reflection in the lower solar chromosphere based on helioseismic analysis of multi-height Doppler data. This evidence is derived through a wave propagation model that incorporates both upward- and downward-traveling (reflected) waves. Moreover, we find that the height of the reflecting region varies with magnetic field strengths in a way that suggests a connection with the the plasma $\beta\sim1$ region. We measure an effective reflection coefficient of $13\,\%$ in a magnetically quiet region of the Sun. Comment: 12 pages, 4 figures, accepted for publication in ApJ |
