| Abstract: | We simultaneously fitted light and velocity data for the star–planet system OGLE-TR-56 with the Wilson–Devinney (WD) binary
star program. We solved for orbital and planet parameters, along with the ephemeris using all currently available observational
data. Parameters for the star (OGLE-TR-56a) were kept fixed at values derived from spectral characteristics and stellar evolutionary
tracks. Our results are in good agreement with parameters obtained by other authors and have slightly smaller errors. We found
no significant change in orbital period that may be due to orbital decay. |
