New Paradigm of Stellar Convection
Tension between solar observations and theoretical and numerical models is shifting the paradigm of stellar convection: simulations produce dominant large-scale flows that are absent in the Sun and the supergranulation scale which according to helioseismology is dominant in the Sun is not captured by simulations. This discrepancy, named the convective conundrum, is the most likely reason why solar differential rotation and global dynamo cannot be reproduced by current simulations. Canonical theory of convection, adopted in many models, assumes an unstable temperature gradient and local driving of convection leading to large-scale flows. More recent models relaxing this assumption suggest…
