Multi-dimensional processes in stellar physics : Evry Schatzman School 2018 /

Mostrar otras versiones (1)

When one has to deal with fluid flows, magnetic fields or heat transfer in stars, one faces the partial differential equations that govern these processes. These phenomena are naturally multi-dimensional and their study requires new and sophisticated models. This volume gathers the lecture notes whi...
