Extended Data Fig. 6: Multi-harmonic model of V1298 Tau TTVs described in Methods.
From: A young progenitor for the most common planetary systems in the Galaxy
The top left panel shows the measured deviations of planet c’s transit times from the best-fitting linear ephemeris. The red lines show draws from credible models. The second panel shows the difference between measured times and the model predictions. Other panels show the same quantities for planets d, b and e. The TTVs of planets c and d are dominated by interactions between the two planets. They are well-described by a sinusoid with an amplitude of ~100 min and a period of Pcd = 1604 ± 12 days. The TTVs of planets b and e are dominated by interactions between the two planets. Here, the TTVs are well-described by a sinusoid with an amplitude of ~50 min and a period of 2852 ± 50 days.
