Analysis of HIP 65 A b Revealing Discrepancies Between Current and Past-Reported Transit Depths

Exoplanet HIP 65 A b is a gas giant of 3 Jupiter masses which orbits every 0.98 days close to its host star, near the Roche Lobe limit within a binary system. Images taken during transits were reduced with the Exoplanet Transit Interpretation Code (EXOTIC) and psx photometry. The depth of the transit was found to be about 2%, significantly smaller than the 8.2% transit depth reported in the NASA Exoplanet Archive. The radius of HIP 65 A b was found to be the same as previously reported, roughly 2 Jupiter radii, which can be explained by the extreme grazing nature of these transits.
