KELT-6, also known as BD+31 2447, is a star in the constellation Coma Berenices. With an apparent magnitude of 10.34, it is impossible to see with the unaided eye, but can be seen with a powerful telescope. The star is located 791 light years away from the Solar System based on parallax, but is drifting away with a radial velocity of 1.62 km/s.
KELT-6 is an F-type star that is 13% more massive and 53% larger than the Sun. It radiates at 3.25 times the Sun's luminosity from its photosphere at an effective temperature of 6,727 K. KELT-6 has a projected rotational velocity of 4.53 km/s, and is slightly older than the Sun, with an age of 4.9 billion years. Unlike most host stars of exoplanets, it has a poor metallicity, with 52.5% the abundance of heavy metals compared to the Sun.
In 2013, a long period "hot Jupiter" was discovered orbiting the star using the transit method.[2] Another planet was discovered in 2015 using radial velocity (Doppler spectroscopy) method.[5]
