    99 oscillating red-giant stars in binary systems with NASA TESS and NASA Kepler identified from the SB9-Catalogue
    Oscillating red-giant stars in binary systems are an ideal testbed for investigating the structure and evolution of stars in the advanced phases of evolution...
  • Publication
    A calibration of the Rossby number from asteroseismology
    Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the...

    A Hot Saturn Orbiting an Oscillating Late Subgiant Discovered by TESS
    We present the discovery of HD 221416 b, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology...
  • Publication
    A search for red giant solar-like oscillations in all Kepler data
    The recently published Kepler mission Data Release 25 (DR25) reported on ˜197 000 targets observed during the mission. Despite this, no wide search for red...
  • Publication
    A seismic and gravitationally bound double star observed by Kepler. Implication for the presence of a convective core
    Context. Solar-like oscillations have been observed by Kepler and CoRoT in many solar-type stars, thereby providing a way to probe stars using asteroseismology...
  • Publication
    Accurate p-mode measurements of the G0V metal-rich CoRoT target HD 52265
    Context. The star HD 52265 is a G0V metal-rich exoplanet-host star observed in the seismology field of the CoRoT space telescope from November 2008 to March...

    Acoustic oscillations and dynamo action in the G8 sub-giant EK Eridani
    We present further evidence of acoustic oscillations in the slowly rotating overactive G8 sub-giant EK Eri. This star was observed with the 1m Hertzsprung SONG...

    An approach to Eddington science using OMC integral data
    The Eddington mission has two primary scientific goals: the study of stellar structure and evolution, and the search of habitable planets. The first one, based...

    An in-depth study of HD 174966 with CoRoT photometry and HARPS spectroscopy. Large separation as a new observable for δ Scuti stars
    Aims: The aim of this work was to use a multi-approach technique to derive the most accurate values possible of the physical parameters of the δ Sct star HD...
