Abstract
The project proposes a novel and original research in the theory of Rossby waves in various
applications of stellar interiors including magnetic dynamo and tidal interaction.
The scientific tasks are:
to study the radial/latitudinal structures of Rossby waves in stellar interiors as well as possible
wave trapping in layers of minimum temperature gradient; to study the coupling of Rossby and
dynamo waves in the dynamo layers of Sun-type stars and their role in activity cycles;
to study the Rossby waves in stellar interiors under the tidal influence of a companion star or
an exoplanet.
Each task of the project will push forward corresponding original research field in the theory of
stellar Rossby waves. The project will be fulfilled by the main proposer, Dr Zaqarashvili, during
4 years. The field of expertise of the proposer includes the theoretical modelling of solar
atmosphere and interior, stellar activity and stellar-planetary interaction. Dr Zaqarashvili has a
long-term experience in Rossby wave theory (including magnetic field influence) with the
relation to solar interior and activity. The fulfilment of project tasks will be coordinated with
international experts from USA, Italy and Spain.
