Description
We present a new inversion methodology that adapts the inversion grid in both radius and co-latitude to the data set and solves the inversion problem through an iterative procedure. This method was tested on state-of-the-art global mode frequency splittings to assess the solar interior rotation rate and its temporal variation. We also explore the influence of different data sets on the interpretation of the dynamics of the solar interior, particularly the spatial extend of the torsional oscillations.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary

    Massive characterisation of subgiants and red giants with TESS (Kepler and Gaia)
    TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

    The Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields including Galactic studies, asteroseismology, and exoplanets, and continue to be an astrophysical gold mine to this day. Because of this, thorough investigations of the ∼200,000 stars observed by Kepler remain of paramount

    Gas Flows in the Central Region of NGC 4593 with Muse
    Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate the role AGN play in the growth and evolution of galaxies. We use MUSE-AO optical spectra of the inner 7''. 5 × 7''. 5 of the nearby Seyfert 1 galaxy NGC 4593 to understand how gas flows in
