Comparison of outgassing and atmospheric escape fluxes across a range of semimajor axes and eccentricities for different stellar types. Each panel corresponds to a specific orbital eccentricity. Colored bands represent the HZs for M-, K-, and G-type stars (R. K. Kopparapu et al. 2013). Solid and dashed lines indicate escape and outgassing fluxes for Earth-like outgassing conditions (moles H2 kg⁻¹ magma), respectively, for different stellar masses. The shaded purple regions highlight where outgassing exceeds escape within the respective HZs, indicating favorable conditions for atmospheric retention.
