Gravito-inertial waves generation by convective plumes

Abdulnour N., Bessila L. , Mathis S., in preparation for Astronomy & Astrophysics

We have developed a semi-analytical framework to model the excitation of gravito-inertial waves by convective plumes, as well as their implications for angular momentum transport.
