  • Asymptotic g modes: Evidenc... Asymptotic g modes: Evidence for a rapid rotation of the solar core
    Fossat, E.; Boumier, P.; Corbard, T. ... Astronomy and astrophysics (Berlin), 08/2017, Volume: 604
    Journal Article
    Peer reviewed
    Open access

    Context. Over the past 40 years, helioseismology has been enormously successful in the study of the solar interior. A shortcoming has been the lack of a convincing detection of the solar g modes, ...

  • The envelope of the power s... The envelope of the power spectra of over a thousand δ Scuti stars
    Barceló Forteza, S.; Roca Cortés, T.; García, R. A. Astronomy and astrophysics (Berlin), 06/2018, Volume: 614
    Journal Article
    Peer reviewed
    Open access

    CoRoT and Kepler high-precision photometric data allowed the detection and characterization of the oscillation parameters in stars other than the Sun. Moreover, thanks to the scaling relations, it is ...

    Barceló Forteza, S.; Roca Cortés, T.; García Hernández, A. ... Astronomy and astrophysics (Berlin), 05/2017, Volume: 601
    Journal Article
    Peer reviewed
    Open access

    Context. Since CoRoT observations unveiled the very low amplitude modes that form a flat plateau in the power spectrum structure of δ Scuti stars, the nature of this phenomenon, including the ...
