    Prediction of close binarity based on nebula morphology
    A thorough search of the OGLE-III microlensing project has more than doubled the total sample of PNe known to have close binary central stars. These discoveries...

    Probing O-enrichment in C-rich dust planetary nebulae
    The abundance of O in planetary nebulae (PNe) has been historically used as a metallicity indicator of the interstellar medium (ISM), where they originated; e.g...

    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...
