HATS-11 b is a gas giant exoplanet in the habitable zone of an F-type star. It was discovered in 2016 as a confirmed exoplanet, or exosolar planet, and has been described as similar to Jupiter. It has a mass of 0.83 Jupiters, takes 3.6 days to complete one orbit around its star, and is 0.0507 AU away from it. It revolves around the star HATS-11. It was discovered in 2016 and was announced.
HATS-11 b is an exoplanet that orbits the star HATS-11, which is 3155.0 light-years (967.3 pc) from our Solar System. Its discovery was made public in 2016. HATS-11 has an apparent magnitude of 14.0 and an absolute magnitude of 4.1. It is 1.3 times more massive and 1.5 times larger than our Sun. The surface temperature is 6563 with its spectral types of G0. In this planetary system, the extrasolar planet HATS-11 b orbits around the star HATS-11 every 3.6 days with its orbital distance of 0.05 AU
Discovery
HATS-11b was discovered in 2016 by the Hungarian Automated Telescope Network (HATNet) using the primary transit method in the HATSouth survey, which aims to discover exoplanets using the transit method. As of February 10th, 2020, 61 exoplanets have been discovered since 2009 (when the HATSouth project began). The radial velocity method was used to calculate the mass of HATS-11b.
Characteristics
HATS-11b is described as being similar to Jupiter and orbiting a subsolar metallicity star 2955 light-years away (906 parsecs). HATS-11b has an orbital period of approximately 3.6 Earth days and a temperature of 1637 Kelvin (1363.85 Celsius). HATS-11b weighs 0.85MJ and has a radius of 1.49RJ. The planet has an elliptical orbit with an orbital eccentricity of 0.34.
Star
HATS-11b is a star that orbits the star HATS-11. The solar mass of HATS-11 is 1M☉, and the solar radius is 1.44R☉. It’s a G0 star with a medium temperature. HATS-11 has a metallicity of around -3.09 Fe/H, which is about one-thousandth the amount of metal found in the Sun. The effective temperature of the star is approximately 6060 Kelvin (5786.85 Celsius). HATS-11 is 7.7 billion years old and has an apparent magnitude of 14, which cannot be seen with the naked eye.
