    White Dwarf Spectral Analysis: Applying Unsupervised Machine Learning to the Gaia XP Coefficients
    Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary...

    White Dwarfs in Close Binaries: A Systematic Search for Mass Transfer Systems and Supernova Ia Progenitors
    White dwarfs are the evolutionary end point of the vast majority of stars (97 per cent),where a large fraction of systems, around 25 per cent, are close enough...

    White Dwarfs in Close Binaries: A Systematic Search for Mass-transfer Systems and Supernova Ia Progenitors in the APOGEE Survey
    We have created a new and unique database, the APOGEE-Galaxy Evolution Explorer (GALEX)-Gaia catalog, to study white dwarfs in close binaries, and, in...

    White dwarfs with infrared excess within 100 pc: Gaia and the Virtual Observatory
    The infrared excess shown by white dwarfs can be an indicator of a low-mass substellar companion, like a brown dwarf or even an exoplanet. In this work, we...

    Why are Massive O-rich AGB Stars in our Galaxy not S-stars?
    We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical...

    Why we need to measure turbulent magnetic fields in HII regions
    We have measured the emission line profiles in Hα from populations of HII regions in nearby spiral galaxies, and extracted their non-thermal line widths. These...
