Pebble accretion efficiency vs planet eccentricity for the default run: M_p = 0.1 M_⊕, M_⋆ = 1 M_⊙, v_hw = 30 m s⁻¹, and τ_s = 10⁻². Eccentricities have been explored from e_p = 6 × 10⁻⁵ to 0.2. The dot gives the mean value, and the errorbar indicates the Poisson counting error. The solid line represents the analytical fit. The efficiency peaks around an eccentricity of 0.03, and this peak efficiency is four times of the circular efficiency when e_p ≃ 0.
