Laboratory of theoretical astrophysics / laboratory of magnetic activity of the sun and stars  

Introduction to MESA stellar evolution code. Description of the possibilities and limitations of the program. Calibration of numerical parameters in order to obtain results that make physical sense. Learning how to model different astrophysical objects: molecular clouds contracting on the main sequence, main sequence stars, red giants, AGB stars, horizontal branch stars, white dwarfs, black holes. Analysis of physical processes in different phases of stellar evolution (nuclear reactions, convection, diffusion of chemical elements, energy transport, mass loss, mixing of matter, angular momentum transport). Modeling the evolution of binary systems with mass exchange between the components./ Calibration methods for spectroscopic observations of solar flares and prominences obtained in the optical range. Ultraviolet spectroscopy and photometry of active solar phenomena. Temporal evolution of stellar and solar flare emissions. Strategies and methods used in the modelling of solar and stellar flares. One-dimensional models of the active atmosphere of the Sun and stars. Distributions of non-thermal electrons in the flaring loop (Fokker-Planck). Diagnostics of star spots based on the photometric modulations. Analysis of solar and stellar activity cycles. Detection of stellar flares in global surveys of the sky.
