Global 3D simulations of convection and dynamos in Red Giants
Carolina Ortiz-Rodríguez, Petri Käpylä, Juan Pablo Hidalgo +2
Understanding the internal dynamics of red giants is essential for studying angular momentum transport and magnetic field generation during stellar evolution. We present three-dime…
