Descripción
δ Sct are one of the most abundant pulsating stars in our Galaxy.
In addition, they have moderate to fast rotations and periods of several
hours. That makes them the suitable targets for studying the effects of
rotation on stellar evolution. In this work, we show how to infer the
mean density and the surface gravity of an A-type pulsanting star only
from its oscillation frequencies. To do this, we used a separation
between frequencies, known as large separation, which is proportional to
the stellar mean density. This is the first step towards a reliable mode
identification of their oscillation modes.
