    The Na-O anticorrelation in horizontal branch stars. IV. M 22
    We obtained high-resolution spectra for 94 candidate stars belonging to the HB of M 22 with FLAMES. Previous works have indicated that this cluster has split...

    The Na-O anticorrelation in horizontal branch stars. V. NGC 6723
    We used FLAMES+GIRAFFE (Medusa mode) at the VLT to obtain moderately high resolution spectra for 30 red horizontal branch (RHB) stars, 4 RR Lyrae variables, and...

    The NaI resonance lines as a spectroscopic test of late-type stellar atmospheres.
    We have tested current models for the atmospheres (including photosphere and low chromosphere) of late-type stars using the D resonance lines of neutral sodium...
