Non-linear models for Delta Scuti stars

Delta Scuti stars are variable stars that with the ultra precise data from spacial satellites like TESS and Kepler have experimented a skyrocketing improvement in their spectra analysis. Special importance for Asteroseismology analysis have the non-linearities that could be observed in their power spectrum, not yet thoroughly studied, because they could explain some of the unsolved enigmas about the phenomenology of these stars.

In this poster, we will be analyzing the nonlinearities of these stars with the aim of solving numerically the non-lineal differential equations that describe their pulsations.
