    Using nitrogen as a tracer of the chemical content of the Universe: from WR nebulae to early star-forming galaxies
    Chemical abundances derived using emission-line spectra in ionized gaseous nebulae are between the most useful properties that can be derived to understand the...

    Variability surveys from today to future extremely large telescopes
    I will make an overview of the classical pulsating variable stars (i.e. SX Phoenicis, RR Lyrae, Anomalous Cepheids, Classical Cepheids) in our Local Group and...

    Vertical magnetic field on the boundary of an evolving pore
    Jurčák criterion states that umbra-penumbra boundaries are defined by a constant vertical magnetic field in stable sunspots. In this seminar I will talk about...

    Warps in galactic H I disks
    Warps of disk galaxies are ubiquitous. In almost every disk galaxy a bending of the disk occurs where the stars fade away and hence where the dark matter halo...
