C/O main sequence for both the ongoing and reset carbon erosion models. The vertical dashed lines show the C/O = 0.4 that initialized the chemical model for the volatile component of the disk. The data from Paper I are also included as faded points to show that the population of warm Jupiters does indeed follow the general trend of the main sequence from Paper I. At the very high C/O end, the population appears to drop away from the trend found at lower C/Os. The planets in this part of the figure have very large masses and are dominated by gas accretion. The colour of each point denotes the trap from which the planet originated: ice line (blue), dead zone (orange), and heat transition (green).
