    A hydrodynamical study of multiple-shell planetary nebulae. III. Expansion properties and internal kinematics: Theory versus observation
    We present the result of a study on the expansion properties and internal kinematics of round/elliptical planetary nebulae of the Milky Way disk, the halo, and...

    A KMOS survey of the nuclear disk of the Milky Way. I. Survey design and metallicities
    Context. In the central few degrees of the bulge of the Milky Way there is a flattened structure of gas, dust, and stars, known as the central molecular zone...

    A large sub-Neptune transiting the thick-disk M4 V TOI-2406
    Context. Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the...

    A multi-planetary system orbiting the early-M dwarf TOI-1238
    Context. The number of super-Earth and Earth-mass planet discoveries has increased significantly in the last two decades thanks to the Doppler radial velocity...

    A multi-wavelength analysis of M 81: insight on the nature of Arp's loop
    Context. The optical ring-like structure detected by Arp (1965) around M 81 (commonly referenced as “Arp's loop”) represents one of the most spectacular...

    A multifrequency maximum-entropy joint analysis of COBE and Tenerife data
    We use data from the Tenerife 10-, 15- and 33-GHz beam-switching experiments along with the COBE 53- and 90-GHz data to separate the cosmic microwave background...

    A multiwavelength analysis of a collection of short-duration GRBs observed between 2012 and 2015
    We investigate the prompt emission and the afterglow properties of short-duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015...

    A near-infrared survey for new low-mass members in α Per
    We present a near-infrared (K'-band) survey of 0.7 square degree area in the α Persei open cluster (age = 90 Myr, distance = 182 pc) carried out with the Omega...
