Description
In this paper we mainly aim at the understanding of temporal evolution and spatial characterization of solar granular and supergranular features. For this purpose we apply an automatic feature-tracking algorithm to three different solar granulation timeseries and to a supergranular timeseries of near-surface divergence fields. The single lifetimes are calculated measuring the time elapsing between the birth and death of each target. In addition, we investigate spatial order of surface flows studying the g2(r) function of time-averaged supergranular fields.

    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

    Signature of the spin-down stalling in the stellar magnetic activity
    Once main-sequence (MS) solar-like stars transitioned from the saturated to the unsaturated regime in magnetic activity, their evolution was perceived as monotonic, with rotation rate and activity gradually decaying. However, Kepler revolutionized this perspective, showing that the unsaturated regime splits into different regimes. One transition

    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
