    Radial metallicity gradients with Galactic nebular probes
    The study of radial metallicity gradients in the disc of the Milky Way is a powerful tool to understand the mechamisms that have been acting in the formation...

    Ram Pressure Stripping in Planetary Nebulae
    We present two-dimensional numerical simulations of the evolution of a low-mass star moving supersonically through its surrounding interstellar medium (ISM). We...

    Recovering lenticular galaxies past histories using planetary nebulae kinematics: the case of NGC1023
    We present a detailed study of the lenticular galaxy NGC 1023 kinematics. To perform this analysis we use planetary nebulae (PNe). which can be observed in the...

    Rediscovering the hydrogen atom
    Common wisdom identifies hydrogen lines in photoionized region with recombination lines. However, these lines can also be excited by different atomic mechanisms...

    Rings in the haloes of planetary nebulae
    We present a search for rings or arcs in the haloes of planetary nebulae (PNe). We discovered such structures in eight PNe, tripling the sample of PNe with...

    Rotating Stars and the Formation of Bipolar Planetary Nebulae. II. Tidal Spin-up
    We present new binary stellar evolution models that include the effects of tidal forces, rotation, and magnetic torques with the goal of testing planetary...
