    The oxygen abundance gradient in M 101: The reliability of the P method
    We present the oxygen abundance determination for 90 H II regions in the inner parts of the grand design galaxy M 101. The abundances were derived employing the...

    The PAU Survey and Euclid: Improving broadband photometric redshifts with multi-task learning
    Current and future imaging surveys require photometric redshifts (photo-zs) to be estimated for millions of galaxies. Improving the photo-z quality is a major...

    The PAU survey: Enhancing photometric redshift estimation using DEEPz
    We present photometric redshifts for 1 341 559 galaxies from the Physics of the Accelerating Universe Survey (PAUS) over 50.38 deg 2 of sky to i AB = 23...

    The Penn State - Toruń Centre for Astronomy Planet Search stars. II. Lithium abundance analysis of the red giant clump sample
    Context. Standard stellar evolution theory does not predict existence of Li-rich giant stars. Several mechanisms for Li-enrichment have been proposed to operate...

    The Penn State - Toruń Centre for Astronomy Planet Search stars. IV. Dwarfs and the complete sample
    Context. Our knowledge of the intrinsic parameters of exoplanets is as precise as our determinations of their stellar hosts parameters. In the case of radial...
