| Título: | An automatic procedure for photometry and astrometry in crowded fields |
| Resumo: | A number of astronomical problems require accurate measurements of the brightness of stars located in crowded fields. These include the search for extrasolar planets, gravitational microlensing amplification events, as well as the search for variable stars. In this work, we describe an automatic procedure for photometry and astrometry in crowded fields using a methodology similar to the one used in DAOPHOT, but with the capability of processing a list of images automatically. Two applications are presented: the light curve of the eclipsing binary BUL SC16 335 and the identification of the flaring components of the astrometric triple LHS 1070. |
