Description
Preliminary results are presented of spectroscopic analysis of ten young stars in OB associations using high resolution spectra and NLTE calculations. From the known distances the stellar masses are derived. The comparison with evolutionary tracks indicates a possible discrepancy between the masses and enhanced helium abundances derived from the tracks and from the analysis.

    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

    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

    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
