KELT-16b is an hot Jupiter located 1,450 light years from Earth that has an ultra-short orbital period of 0.96 days that orbits around a F-type main sequence star named TYC 2688-1839-1. It has 2.75 Jupiter masses and a radius of 1.415 Jupiter radii.[1][2]
KElT-16b is highly irradiated due to its host star. This makes the temperature of KELT-16b around 2453 Kelvin. It is possible that KELT-16b may be driving inward towards its star due to Kozai-livdov oscillations (Kozai mechanism).[1] The atmosphere of KELT-16b is probably more Oxygen-rich then Carbon-rich.[3]
