    Analysis of the acoustic cut-off frequency and high-frequency peaks in six Kepler stars with stochastically excited pulsations
    Gravito-acoustic modes in the Sun and other stars propagate in resonant cavities with a frequency below a given limit known as the cut-off frequency. At higher...

    Asteroseismic Fundamental Properties of Solar-type Stars Observed by the NASA Kepler Mission
    We use asteroseismic data obtained by the NASA Kepler mission to estimate the fundamental properties of more than 500 main-sequence and sub-giant stars. Data...

    Asteroseismology of 19 low-luminosity red giant stars from Kepler
    Context. Frequencies of acoustic and mixed modes in red giant stars are now determined with high precision thanks to the long continuous observations provided...
  • Publication
    Asteroseismology of iota Draconis and Discovery of an Additional Long-period Companion
    Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted...
