    Photospheric magnetic topology of a north polar region
    Aims: We aim to characterise the magnetism of a large fraction of the north polar region close to a maximum of activity, when the polar regions are reversing...

    Physical conditions in the partially ionized zone of the Orion nebula
    We report the first reliable measurement of the nebular [O i] lambda 5577 emission line in the Orion nebula. Diagnostic diagrams based on the [O i] lambda...

    Physical limits to the validity of synthesis models. The Lowest Luminosity Limit
    In this paper we establish a necessary condition for the application of stellar population synthesis models to observed star clusters. Such a condition is...

    Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group
    Context. Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late...
