Notes. Stars are set at 47 pc distance, with solar abundances, and rotational velocities typical of the chosen type. (†)veq sin(i) is set to the Casasayas-Barris et al. (2021) value (4.23 km s−1) for HD209458 in Sect. 4.1. (‡)λ is set to different values (from −90 to 90) in Sects. 3 and 4.2. (a)Stassun et al. (2019), (b)Torres et al. (2008), (c)Addison et al. (2019), (d)Bourrier et al. (2022), Nagel et al. (2023). (e)Casasayas-Barris etal. (2021).
