    The multifarious ionization sources and disturbed kinematics of extraplanar gas in five low-mass galaxies
    Aims: We investigate the origin of the extraplanar diffuse ionized gas (eDIG) and its predominant ionization mechanisms in five nearby (17-46 Mpc) low-mass (10...

    The MURALES survey. IV. Searching for nuclear outflows in 3C radio galaxies at z &lt; 0.3 with MUSE observations
    We analyze VLT/MUSE observations of 37 radio galaxies from the Third Cambridge catalogue (3C) with redshift < 0.3 searching for nuclear outflows of ionized gas...

    The mysterious eruption of V838 Mon
    V838 Mon is marking one of the most mysterious stellar outbursts on record. The spectral energy distribution of the progenitor resembles an under-luminous F...

    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...
