    Using reduction and inversion tools for THEMIS-MTR data: chromospheric reversals of a moving magnetic feature and an ephemeral region .
    New tools have been developed for THEMIS spectropolarimetric data. In this paper we present how these tools work and can be used in order to understand two...

    Using symmetries and generating functions to calculate and minimize moments of inertia
    This paper presents some formulae to calculate moments of inertia for solids of revolution and for solids generated by contour plots. For this, the symmetry...

    Using the Tremaine-Weinberg method to measure pattern speeds from Halpha velocity maps.
    The Tremaine-Weinberg method is a well-known model-independent technique for measuring density wave pattern speeds in spiral galaxies. Here we show how it can...

    UV and optical quantitative spectroscopy of early B-type supergiants in M 33
    We present the analysis of UV and optical spectra of M 33 early B-type supergiants. Stellar parameters, metal abundances (Si, Mg, O and N) and mass loss rates...
