The effects of granulation and supergranulation on Earth-mass planet detectability in the habitable zone around F6-K4 stars

N. Meunier,
A. M. Lagrange

Abstract: Context. The detectability of exoplanets and the determination of their projected mass in radial velocity are affected by stellar magnetic activity and photospheric dynamics. Among those processes, the effect of granulation, and even more so of supergranulation, has been shown to be significant in the solar case. The impact for other spectral types has not yet been characterised. Aims. Our study is aimed at quantifying the impact of these flows for other stars and estimating how such contributions affect their… Show more
