Notes. vrot(init) refers to the input initial surface rotational velocity, and vstable is the value corresponding to a stable surface rotational velocity caused by the efficient angular momentum transport due to a Spruit-Tayler dynamo and the fully diffusive treatment of angular momentum transport. Δt is the age of the model at stabilization.
