Abstract
Trans-Neptunian Objects (TNOs) are the historical witnesses of the early Solar System and can provide astronomers much valuable knowledge about their formation and dynamical evolution. The current understanding of their properties, however, such as the total mass, orbital parameters and the sizes distribution, is still far from complete. Here we will present a study of re-examination of COROT asteroseismology lightcurves for the search of small TNOs. The total observation time available in this work is about 144408.3 star-hours. We will analyze these fast photometry lightcurves data to search for serendipitous occultations by passing TNOs. Occultation method is a powerful tool to detect small Solar System bodies through their diffraction phenomenon[1]. The method of occultation will allow revealing the existence of TNOs that have sizes about several kilometers.
