exoplanet, differential photometry, light curveAbstract
The discovery of the first exoplanet outside the Solar System inaugurated a new field ofintense scientific investigation in Astronomy, opening up several perspectives for studiesthrough different techniques in observatories installed on the ground and in space. Thediscoveries made already accumulate, currently, more than 4500 exoplanets confirmed inmore than 3300 planetary systems. As part of the Scientific Initiation studies carried out at DFIS/UEFS, this contribution describes the main results related to the exoplanet WASP-2 A b, discovered in 2006 through the Planetary Transit technique. The photometric observations carried out at the Antares Astronomical Observatory - UEFS with the MEADE 10" LX200 GPS telescope, the CCD SBIG ST-7XME-D and the ExoPlanet-BB (Blue Block-ing) filter were sufficient to carry out a preliminary study of the light curve obtained withthe MaxIm DL software and confirm the feasibility of starting a potential observationalprogram with the now available small aperture telescopes: MEADE and CDK20.
