Effects of Full-sphere Convection on M-dwarf Dynamo Action, Flux Emergence, and Spin-down

Effects of Full-sphere Convection on M-dwarf Dynamo Action, Flux Emergence, and Spin-down

We present an analysis of 21 global MHD simulations of the dynamo action taking place in the interiors of fully convective M4 stars. We leverage our past work involving 45 simulations of shell-convecting-type M2 stars in a very similar parameter space to identify properties that their dynamos share...
