TAK National Observatory, Turkey. The new transit light curves of both systems were analyzed using WinFitter code. Planetary radii of HAT-P25b and WASP-11b/HAT-P-10b were found to be 1.18 +/- 0.11RJ and 1.02 +/- 0.09RJ, respectively. Transit ephemerides were updated and transit timing variation (TTV) analyses were performed using all mid-transit times published in the literature together with ours.eninfo:eu-repo/semantics/closedAccessNew Photometric Observations of HAT-P-25b and WASP-11b/HAT-P-10bConference Object204210.1063/1.5078885N/AWOS:0004683589000132-s2.0-85057171920Q4
