    Seismic analysis of HD 43587Aa, a solar-like oscillator in a multiple system
    Context. The object HD 43587Aa is a G0V star observed during the 145-day LRa03 run of the COnvection, ROtation and planetary Transits space mission (CoRoT), for...
  • Publication
    Seismic and spectroscopic analysis of nine bright red giants observed by Kepler
    Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red giant stars and to measure their...
  • Publication
    Seismic constraints on the radial dependence of the internal rotation profiles of six Kepler subgiants and young red giants
    Context. We still do not understand which physical mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed...

    Signatures of Magnetic Activity: On the Relation between Stellar Properties and p-mode Frequency Variations
    In the Sun, the properties of acoustic modes are sensitive to changes in the magnetic activity. In particular, mode frequencies are observed to increase with...
  • Publication
    Solar-like oscillations and ellipsoidal variations in TESS observations of the binary 12 Boötis
    Binary stars in which oscillations can be studied in either or both components can provide powerful constraints on our understanding of stellar physics. The...

    Solar-like Oscillations in KIC 11395018 and KIC 11234888 from 8 Months of Kepler Data
    We analyze the photometric short-cadence data obtained with the Kepler mission during the first 8 months of observations of two solar-type stars of spectral...
  • Publication
    Solar-like oscillations in red giants observed with Kepler: comparison of global oscillation parameters from different methods
    Context. The large number of stars for which uninterrupted high-precision photometric timeseries data are being collected with Kepler and CoRoT initiated the...
  • Publication
    Solar-like oscillations in γ Cephei A as seen through SONG and TESS. A seismic study of γ Cephei A
    Context. Fundamental stellar parameters such as mass and radius are some of the most important building blocks in astronomy, both when it comes to understanding...
  • Publication
    Spectroscopic and seismic analysis of red giants in eclipsing binaries discovered by Kepler
    Eclipsing binaries (EBs) are unique targets for measuring accurate stellar properties and constraining stellar evolution models. In particular, it is possible...
