    Precise radial velocities of giant stars. XV. Mysterious nearly periodic radial velocity variations in the eccentric binary ε Cygni
    Context. Using the Hamilton Échelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars...

    Precision measurement of a brown dwarf mass in a binary system in the microlensing event. OGLE-2019-BLG-0033/MOA-2019-BLG-035
    Context. Brown dwarfs are transition objects between stars and planets that are still poorly understood, for which several competing mechanisms have been...

    Predicted asteroseismic detection yield for solar-like oscillating stars with PLATO
    Aims: In this work, we determine the expected yield of detections of solar-like oscillations for the targets of the foreseen PLATO ESA mission. Our estimates...

    Preparing for LSST data. Estimating the physical properties of z < 2.5 main-sequence galaxies
    Aims: We study how the upcoming Legacy Survey of Space and Time (LSST) data from the Vera C. Rubin Observatory can be employed to constrain the physical...

    Preparing the COROT space mission: Incidence and characterisation of pulsation in the lower instability strip
    By pursuing the goal to find new variables in the COROT field-of-view we characterised a sample of stars located in the lower part of the instability strip. Our...

    Probable brown dwarf companions detected in binary microlensing events during the 2018-2020 seasons of the KMTNet survey
    Aims: We inspect the microlensing data of the KMTNet survey collected during the 2018-2020 seasons in order to find lensing events produced by binaries with...

    Probing 3D and NLTE models using APOGEE observations of globular cluster stars
    Context. Hydrodynamical (or 3D) and non-local thermodynamic equilibrium (NLTE) effects are known to affect abundance analyses. However, there are very few...

    Probing deep photospheric layers of the quiet Sun with high magnetic sensitivity
    Context. Investigations of the magnetism of the quiet Sun are hindered by extremely weak polarization signals in Fraunhofer spectral lines. Photon noise...

    Probing downflows in solar magnetic elements: the Fe II test
    In an attempt to assess the physical realism of the plage flux tube model derived by Bellot Rubio, Ruiz Cobo & Collados (cite{brc}, cite{bellot}) we extend its...
