Resumen:
In this contribution we present a search for Planemos (Planetary Mass Objects) in the L 1495 dark cloud, belonging to the Taurus molecular complex. The observations were obtained in the K (2.2 microns) and H (1.6 microns) bands with the near-IR instrument CAMILA, attached to the 2.1 m telescope of the San Pedro Martir Observatory, in Baja California, Mexico. These observations have been supplemented with data from the 2MASS, which cover a larger area and provide magnitudes in J (1.25 microns) band. We used the Baraffe et al. (1998; 2002) and Chabrier et al. (2000) pre-main sequence evolutionary model to select about 90 planetary mass candidates with magnitudes and colors roughly corresponding to objects with masses between 4 and 15 M_Jup and ages of few Myr, in the Taurus molecular cloud. However more accurate photometry is necessary to confirm the magnitudes and colors of these candidate objects. If confirmed, this result may indicate that Planemos are very common in our Galaxy.
