RESUMO:

The pulsation of the stars has become, from decades to now, one of the main mechanisms to obtain information about their interiors. With the advent of the missions, the need to understand how
global parameters of the star behaved in relation to the modes is crucial to the entire study of stellar evolution, especially in the Red Giant Branch. Many computational codes use inferential statistics for gather
information, all very peculiar to evolutionary states since the main sequence
until the asymptotic giant branch. Our work was to develop a tool
which will serve as a basis for new trials and works, within the Asteroseismology of Clump stars, which obtain the values of maximum oscillation frequency and the separations between these frequencies are pillars for stellar physical understanding. Herein to this, the correct modeling associated with the inclusion of metallicity obtained
from spectroscopy, may generate changes, not yet fully understood
in the seismic scales relations for mass and radius. In this way, the study of seismology of Clump stars may be the key to a promising scenario for Archeology Galactic and for the complete understanding of processes in the stellar interior.
