    Non-detection of magnetic fields in the central stars of the planetary nebulae NGC 1360 and LSS 1362.
    A large fraction of planetary nebulae (about 80%) are bipolar or elliptical rather than spherically symmetric. Modern theories invoke magnetic fields, among...

    On the magnetic nature of quiet-Sun chromospheric grains
    CaII Kgrains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the...

    On the origin of stars with and without planets. Tc trends and clues to Galactic evolution.
    We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature...
