    Preliminary results on the determination of the theoretical non-adiabatic observable phase lag (ψT) using VIRGO color photometry
    The helioseismic instruments aboard the SOHO satellite make it possible to measure solar oscillations as variations of the irradiance (VIRGO) or as variations...

    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 Na in giant exoplanets with ESPRESSO and 3D NLTE stellar spectra
    Context. Neutral sodium was the first atom that was detected in an exoplanetary atmosphere using the transmission spectroscopy technique. To date, it remains...

    Probing the Upper Scorpius mass function in the planetary-mass regime
    We present the results of a deep ZYJ near-infrared survey of 13.5 deg2 in the Upper Scorpius (USco) OB association. We photometrically selected ˜100 cluster...

    Prolate rotation and metallicity gradient in the transforming dwarf galaxy Phoenix
    Transition type dwarf galaxies are thought to be systems undergoing the process of transformation from a star-forming into a passively evolving dwarf, which...

    Proper motions and velocity asymmetries in the RW Aur jet
    We present adaptive optics spectro-imaging observations of the RW Aur jet in optical forbidden lines, at an angular resolution of 0.4''. Comparison with HST...
