HATS-7: A Cool Star and Its Close-Orbiting Giant
HATS-7 is a K2 star located 785 light-years away, with a mass of 0.849 solar masses and a radius of 0.815 solar radii. Its temperature is 4990 K, and it is 7.8 billion years old. This system hosts one known planet.
That planet is HATS-7 b, a Jupiter-like world discovered by the transit method in 2015. It has a mass of 38.1 Earth masses and a radius of 6.31 Earth radii, orbiting its star every 3.19 days. Its mean density is 0.836 g/cm³, which is 0.152 times Earth's. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
