Comparison of the oscillations of network and internetwork versus height in
the solar atmosphere (PNST)
F. Baudin, K. Bocchialini and S. Koutchmy
The oscillations of the solar atmosphere are studied based on several time
series obtained in different lines (Na D1, He D3, Mg b2, Halpha, Hbeta,
FeI, CaI) with the telescope Themis and its spectrograph MTR. The
behaviour of the oscillations is compared in the network and internetwork
regions and also at different height in the solar atmosphere. We discuss the
possibility to identify the occurence of propagating waves taking into account
the expected formation heights of the measured lines.
