Identifying Possible Small Stars with Extrasolar's Planets

For years the man has always wondered whether we are alone in the universe, whether there will planets like ours, which may be habitable. A couple of years it was discovered a possible habitable extrasolar's planet called Gliese 581 g, which has an adequate orbit around its star to find liquid water. The same is 20 light years from Earth. In this research work, we are looking for small stars which have exoplanets as mentioned above. We have a sample of 185 variable stars, smaller than our Sun and relatively close to our planet. For each of these stars have made identification cards which establishes its position in the sky for 2000 and its possible position for the year 2012 (in which it will be observed). To this has had to use a mathematical formula because of the proper movements of the stars, these stars are constantly moving in the sky. It also sets the magnitudes of the filters Visible (V) and infrared (I) of stars, and the coordinates of the center of a field of 7.9 'x 7.9', which will be the observed field. Most of these stars have been placed without any problem, but it was found that some of these stars - because of its proximity to another bright star - cannot be studied properly.
