HD 132563 b: A Giant Planet Orbiting an F8 Star

HD 132563 is a star 343 light-years from Earth with a spectral type of F8. It is a single host to one known planet, HD 132563 b, discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion.

The host star is 2.31 billion years old, with a mass of 1.08 solar masses, a radius of 1.09 solar radii, and a temperature of 6070 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.

HD 132563 b has a minimum mass of 474 Earth masses and an orbital period of 1540 days. A minimum mass is a lower bound on a planet's true mass, differing from an ordinary mass estimate. That minimum mass is larger than Earth's and roughly 1.49 times Jupiter's mass. The radial velocity method revealed the planet through the repeated wobbles its gravity induced in the star's motion.
