Azimuthally averaged gas surface density for models of h/r = 0.05, 0.07, and 0.1 are shown from left to right. Disks with α = 10−4, 10−3, 10−2 are shown from top to bottom. Blue, yellow, green, red, and purple curves represent the gas surface density for planet masses Mp = 11 M⊕, 33 M⊕, 0.3 MJ, 1 MJ, and 3 MJ, respectively, if M* = M⊙. The dashed curves show the cases with visible asymmetry at the gap edge in Figure 1.
