Asteroseismology of A to F-type Stars Using Satellite Data: Delta Scuti Pulsators

Resumo

Delta Scuti are main-sequence intermediate-mass stars. They form part of the grou known as classical pulsators, because they were discovered in the early years of Astronomy. However, due to some characteristics in their pulsating behaviour, they are not well understood yet (above all, compared to the solar type stars) Delta Scuti stars are interesting objectives of study. Their range of masses makes them suitable laboratories for understanding several processes of the internal structure during the stellar evolution. On the other hand, the increasing o the discovering of A to F-type stars harbouring planets enhances the interest in obtaining a good characterization of the system. As I will show you, the asteroseismology study of satellite data could help us to achieve these objectives. However, life is not so easy…
