Abstract In this work, the pulsation analysis is performed on 83 high-amplitude δ Scuti stars (HADS), which have been observed by Transiting Exoplanet Survey Satellite. The results show that 49 of these HADS single-mode pulsation, 27 them radial double-modes (in 22 pulsate with fundamental and first overtone modes five second modes), seven triple-modes (three are newly confirmed triple-mode HAD...

Granada oscillation code (GraCo) is a software constructed to compute adiabatic and non-adiabatic oscillation eigenfunctions and eigenvalues. The adiabatic version gives the standard numerical resolution, and also the Richardson extrapolation, different sets of eigenfunctions, different outer mechanical boundary conditions or different integration variables. The non-adiabatic version can includ...
