In the last few years Asteroseismology has contributed to the knowledge of stellar interior, in some extend. This contribution has been done with -observations, providing the characteristics of the acuostic modes of stellar oscillations; and with theory relating them to inner parameters, locating stars in the JCD diagram (Christesen-Dalsgaard J., 1989). At the beginning only classical pulsating stars had high enough amplitudes able to be detected. But techniques have been improved and now the goal is the detection of oscillations in all kind of stars, specially solar-like ones. Up to now, few cases of possible detections have been reported, the best evidences are: Belmonte et al (1990) in an FV star, Brown et al (1991) on the subgigant Procyon, and Pottasch et al (1992), in α Cen.
