The kinematic Kelvin–Helmholtz instability-driven dynamo: implications for merging compact objects
The kinematic Kelvin–Helmholtz instability-driven dynamo: implications for merging compact objects

Shear, unstable billows, and a rapid dynamo: how merging neutron stars can build magnetar-strength magnetic fields in roughly 0.1 ms.

How merging neutron stars amplify magnetic fields

Our new preprint traces the Kelvin–Helmholtz dynamo from shear winding to three-dimensional magnetic amplification. The models predict magnetar-strength fields on roughly 0.1 ms timescales in neutron-star mergers.
