Notes. Values are the same as those used or derived in Casasayas-Barris et al. (2020), except for the rotational velocity of the star and sky-projected spin-orbit angle of the planet, taken from Casasayas-Barris et al. (2021). Parameters that we vary in the study:(†) Sect. 3 set to 3 and 20;(††) Sect. 3 set to 90;(†††) Sect. 3 set to 0 and 45.
