1. Kore: the numerical explorer of rapidly rotating planets with liquid cores

Kore is a numerical code for the exploration of motions in the liquid cores of rapidly rotating planets. Kore, from the Greek Κόρη, the queen of the underworld, daughter of Zeus and Demeter, solves the linear Navier-Stokes and magnetic induction equations for a viscous, incompressible and conductive fluid (the planet's liquid core) enclosed within a solid inner core and a rigid mantle.
