    Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?
    We report the confirmation of a transiting planet around the bright weakly active M0.5 V star TOI-1235 (TYC 4384-1735-1, V ≈ 11.5 mag), whose transit signal was...
  • Publication
    Precise mass determination for the keystone sub-Neptune planet transiting the mid-type M dwarf G 9-40
    Context. Despite being a prominent subset of the exoplanet population discovered in the past three decades, the nature and provenance of sub-Neptune-sized...

    Precise radial velocities of giant stars. XIII. A second Jupiter orbiting in 4:3 resonance in the 7 CMa system
    We report the discovery of a second planet orbiting the K giant star 7 CMa based on 166 high-precision radial velocities obtained with Lick, HARPS, UCLES, and...

    Precision Ephemerides for Gravitational Wave Searches. II. Cyg X-2
    Accreting neutron stars in low-mass X-ray binaries are candidate high-frequency persistent gravitational wave sources. These may be detectable with next...
  • Publication
    Precision Ephemerides for Gravitational-wave Searches - III. Revised system parameters of Sco X-1
    Neutron stars (NSs) in low-mass X-ray binaries are considered promising candidate sources of continuous gravitational waves. These NSs are typically rotating...
  • Publication
    Precision Ephemerides for Gravitational-wave Searches - IV. Corrected and refined ephemeris for Scorpius X-1
    Low-mass X-ray binaries have long been theorized as potential sources of continuous gravitational-wave radiation, yet there is no observational evidence from...

    Precision Ephemerides for Gravitational-wave Searches. I. Sco X-1
    Rapidly rotating neutron stars are the only candidates for persistent high-frequency gravitational wave emission, for which a targeted search can be performed...

    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...
