KELT-4 A b: A Giant Planet Orbiting a Hot Star
KELT-4 A is an F-type star located 711 light-years away. It has an age of 4.44 billion years, a mass of 1.2 solar masses, a radius of 1.6 solar radii, and a temperature of 6210 K. Its reported mass estimate is larger than the Sun's, and its reported radius estimate is larger than the Sun's. The star is also hotter than the Sun. One planet orbits this host.
KELT-4 A b is a Jupiter-like planet discovered by transit in 2016. It completes an orbit in 2.99 days. Its radius is 19 Earth radii, larger than Earth's, and its mass is 287 Earth masses, also larger than Earth's. Its mean density is 0.229 g/cm³, 0.0415 times Earth's.
