Left panel: final planet masses and semi-major axes from simulations that formed a giant planet with final semi-major axis a_p > 50 au and final mass m_p > 1 M_J. Each planet’s final eccentricity is colour-coded, whilst the red diamond denotes the expected mass and semi-major axis of HIP 65426b. Right panel: final planet masses and semi-major axes from all simulations. Each planet’s final eccentricity is colour-coded. Red diamonds now display the observed directly imaged planets (data taken from exoplanet.eu).
