Resumen:
We present the first results of a photometric search for transiting
exoplanets using the Very Large Telescope. The faintest stars in the
field for which we obtain precise enough lightcurves (V ≈ 20) are
three magnitudes fainter than the typical Optical Gravitational Lensing
Experiment (OGLE) candidates. The obtained precision should be enough to
detect Neptune-sized planets orbiting Sun-like stars or even
Super-Earths transiting M-dwarf stars. However, most of the faintest
lightcurves are dominated by systematics which must be filtered before
any attempt to detect transit-like features.
