Query: Bridging planets and stars using scaling laws in anelastic spherical
  shell dynamos   Dynamos operating in the interiors of rapidly rotating planets and low-mass
stars might belong to a similar category where rotation plays a vital role. We
quantify this similarity using scaling laws. We analyse direct numerical
simulations of Boussinesq and anelastic spherical shell dynamos. These dynamos
represent simplified models which span from Earth-like planets to rapidly
rotating low-mass stars. We find that magnetic field and velocity in these
dynamos are related to the available buoyancy power via a simple power law
which holds over wide variety of control parameters.
