Influence of different aspect ratios with α = 10⁻² and m_init = 20 M_⊕. Top: time evolution of the planetary accretion rate. The flip in the accretion rate occurs at different moment (i.e., different planet mass) due to the dependence on h of the Machida accretion rate (Eq. (2)). As the time needed for the initial mass to reach an equilibrium is higher for lower aspect ratios, gas accretion starts later for h = 0.03 (see Table 2). Middle 1: evolution of the accretion rates as a function of the time after gas accretion is turned on. Middle 2: time evolution of the planetary mass. Lower aspect ratios result in more massive planets. Bottom: perturbed surface density at the time where m_p = 0.5 M_J (dots on previous panels). The two effects added up here make the gap shapes really different, namely, the influence of the aspect ratio on the shape of the gap and the time at which the planet reaches 0.5 M_J. We comparethe gap shapes of accreting planets with gaps created by fixed mass planets: depending on the aspect ratio, gas accretion has a different influence. The horizontal gray dashed line marks the gap-opening criterion as defined by Crida et al. (2006).
