Extended Data Fig. 4: Flyby field strength.
From: A modern dynamo at Triton as a consequence of its capture by Neptune
a, A simplified trajectory of a hypothetical flyby of Triton. b, The predicted strength of a dynamo field during a notional flyby with a closest approach of 400 km to Triton’s surface, based on the nominal FeS layer model at 4.5 Gyr, compared to the simulated strength of an ocean-induced magnetic field. c, A more detailed view of the simulated ocean-induced magnetic field strength.
