Abstract

Detailed analysis of free parameters of the Florida-Budapest turbulent convective stellar model were carried out. A recent explanation of the Blazhko effect ties the observed modulation to convective structure changes inside the star. Before modelling this process, we test relations of growth rates and linear periods to the free parameters. This information is required to model the varying physical characteristics in the code appropriately. Our analysis shows that parameters related to the properties of the turbulent convective zone have the potential to create variations in pulsation periods and amplitudes, however the magnitudes may not be sufficient.
