  We report the discovery of fourteen new ZZ Cetis with the 4.1m Southern
Astrophysical Research telescope, at Cerro Pachon, in Chile. The candidates
were selected from the SDSS (Sloan Digital Sky Survey) DA white dwarf stars
with Teff obtained from the optical spectra fit, inside the ZZ Ceti instability
strip. Considering these stars are multi-periodic pulsators and the pulsations
propagate to the nucleus of the star, they carry information on the structure
of the star and evolution of the progenitors. The ZZ Cetis discovered till 2003
are mainly within 100 pc from the Sun, and probe only the solar vicinity. The
recently discovered ones, and those reported here, may sample a distinct
population as they were selected mainly perpendicular to the galactic disk and
cover a distance up to ~400pc.
