    (2003) Poretti, E; Garrido, R; Amado, P J; Uytterhoeven, K; Handler, G; Alonso, R; Martin, S; Aerts, C; Catala, C; Goupil, M J; Michel, E; Mantegazza, L; Mathias, P; Pretorius, M L; Belmonte, J A; Claret, A; Rodríguez, E; Suarez, J C; Vuthela, F F; Weiss, W W; Ballereau, D; Bouret, J C; Charpinet, S; Hua, T; LYftinger, T; Nesvacil, N; Van\'t Veer-Menneret, C
    By pursuing the goal to find new variables in the COROT field-of-view we characterised a sample of stars located in the lower part of the instability strip. Our sample is composed of stars belonging to the disk population in the solar neighbourhood. We found that 23% of the stars display multiperiodic light variability up to a few mmag in amplitude, i.e., easily detectable on a single night of photometry.
