Notes and references for each individual system of the P-type (circumbinary) database. This is only a highlight of the full notes that can be accessed at the following URL: https://exoplanet.eu/planets_binary_notescirc/.
| DP Leo | planet detected by timing by Qian et al. (2010) / Post-common envelope cataclysmic binary |
| NN Ser | First planets hinted at in Beuermann et al. (2010), still debated but claimed as probably confirmed by Özdönmez et al. (2023). Planets’ characteristics not fully constrained yet / Post-common envelope cataclysmic binary |
| Kepler-64* (PH1) | Planet by Kostov et al. (2013) and Schwamb et al. (2013) / Quadruple system with another (60au separated) binary at 1000au from the central one. Rare case of planet on both a P-type and an S-type orbit |
| b Cen (HD129116) | Planet by Janson et al. (2021), whose eccentricity is very loosely constrained (0.4 ± 0.4)/ stellar companion by Rizzuto et al. (2013) / Stellar masses derived by Squiciarrini (2025, personal communication) |
