Description
In this work we investigate p-mode power variation with solar
atmosphere. To this aim, we use THÉMIS observations of the Na D1
(λ5896 Å) and K (λ7699 Å) spectral lines. While
the formation heights of the K spectral line are essentially located in
the photospheric layer, the formation heights of the Na D1 line span a
much wider region: from photosphere up to chromosphere. Hence, we had
the opportunity to infer p-mode power variation up to the chromospheric
layer. By analyzing power spectra obtained by temporal series at
different points of the Na D1 and K spectral lines, we confirm and
quantify the increase in p-mode power towards higher atmospheric layers.
Furthermore, the large span in formation heights of the Na D1 line
induces a larger enhancement of p-mode power with solar atmosphere
compared to the K spectral line.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
