Extended Data Fig. 4: Generation of the mean poloidal-magnetic flux inside the merger remnant.
From: A large-scale magnetic field produced by a solar-like dynamo in binary neutron star mergers

Mean poloidal-magnetic flux as a function of the time after the merger. Blue and green-solid curves denote the flux on the sphere of r = 8 and 20 km, respectively, which are representative for the magnetorotational instability inactive and active region, in the simulation with Δxfinest = 12.5 m. The dashed counterparts denote the simulation with Δxfinest = 200 m.
