    Photospheric activity, rotation, and radial velocity variations of the planet-hosting star CoRoT-7
    Context. The CoRoT satellite has recently discovered the transits of an Earth-like planet across the disc of a late-type magnetically active star dubbed CoRoT-7...

    Photospheric activity, rotation, and star-planet interaction of the planet-hosting star CoRoT-6
    Context. The CoRoT satellite has recently discovered a hot Jupiter that transits across the disc of a F9 main-sequence star called CoRoT-6 with a period of 8...

    Photospheric and chromospheric magnetic activity of seismic solar analogs. Observational inputs on the solar-stellar connection from Kepler and Hermes
    We identify a set of 18 solar analogs among the seismic sample of solar-like stars observed by the Kepler satellite rotating between 10 and 40 days. This set is...

    Photospheric downward plasma motions in the quiet Sun
    Context. We analyze spectropolarimetric data taken with the Hinode spacecraft in quiet solar regions at the disk center. Distorted redshifted Stokes V profiles...

    Photospheric Hanle diagnostic of weak magnetic dipoles in stars
    Aims: We propose and explore a new diagnostic technique based upon the linear polarization emitted in Hanle-sensitive lines in disk-integrated stars where a...

    Photospheric magnetic topology of a north polar region
    Aims: We aim to characterise the magnetism of a large fraction of the north polar region close to a maximum of activity, when the polar regions are reversing...

    Photosynthetic Fluorescence from Earthlike Planets around Sunlike and Cool Stars
    Remote sensing of the Earth has demonstrated that photosynthesis is traceable as the vegetation red edge (VRE), which is a steep rise in the reflection spectrum...

    Physical and dynamical characterization of hyperbolic comet C/2017 U7 (PANSTARRS)
    We present here a dynamical and observational study of the comet C/2017 U7 (PANSTARRS). This comet was discovered in 2017 and found to have a hyperbolic orbit...

    Physical and dynamical properties of the anomalous comet 249P/LINEAR
    Images and low-resolution spectra of the near-Earth Jupiter family comet (JFC) 249P/LINEAR in the visible range obtained with the instrument OSIRIS in the 10.4...
