Study of the deuterium Lyman-alpha emission observed with the "low resolution mode"of MAVEN/IUVS

Résumé

We studied a set of observations of the Lyman-α profile by MAVEN/IUVS using the low resolution mode. The brightness profile in the lower corona, especially the bright limb, is best reproduced with a deuterium population during the southern summer as expected from the high resolution echelle mode observations. Therefore it is possible to derive information on the atomic deuterium density at this season not only from the echelle mode but also from the coarser spectral resolution.
