  • 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 Fourth S-PLUS Data Release: 12-filter photometry covering 3000 square degrees in the southern hemisphere
    Context. The Southern Photometric Local Universe Survey (S-PLUS) is a project to map ~9300 sq deg of the sky using twelve bands (seven narrow and five broadbands). Observations are performed with the T80-South telescope, a robotic telescope located at the Cerro Tololo Observatory in Chile. The survey footprint consists of several large contiguous

  • Asteroseismic grid-modelling of the binary system KIC 9163796
    The age of a star cannot be measured but only inferred from observational quantities related to age. For stars in the red-giant phase, classical methods such as isochrone fitting can deliver ages with statistical uncertainties between 30% and 50%. Asteroseismic modelling is known to provide the most precise ages for red giants to date. Furthermore

  • Kepler meets Gaia: Binary systems, color-magnitude diagram, and kinematic analysis
    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

  • Measuring stellar long surface rotation periods by combining multi-sector/cycle long-cadence data from TESS
    The evolution of surface magnetic features on stars, such as spots and faculae, produces modulations in light curves. These modulations allow us to measure the surface rotation period, P_rot, of stars from the main sequence (e.g., McQuillan et al. 2014; Santos et al. 2019, 2021) to the red-giant (Ceillier et al. 2017) phase. Nevertheless, the

  • Spectroscopy and asteroseismic modelling of the red giant binary system KIC 10841730
    Stellar modelling is crucial for understanding the structure and age of stars. The accuracy of a stellar model is limited by the constraints from observations and the theory behind the physical processes. Gravitationally bound stars of a binary system provide an excellent opportunity for a combined study, which provides strong constraints on the
