    New near-infrared JHKs light-curve templates for RR Lyrae variables
    We provide homogeneous optical (UBVRI) and near-infrared (NIR, JHK) time series photometry for 254 cluster (ω Cen, M 4) and field RR Lyrae (RRL) variables. We...

    New Theoretical Period-Luminosity-Metallicity Relations for RR Lyrae in the Rubin-LSST Filters
    The revolutionary power of future Rubin-LSST observations will allow us to significantly improve the physics of pulsating stars, including RR Lyrae. In this...

    New very massive stars in Cygnus OB2
    Context: The compact association Cygnus OB2 is known to contain a large population of massive stars, but its total mass is currently a matter of debate. While...
