WASP-52

WASP-52 is a K-type main-sequence star about 570 light-years away. It is older than the Sun at billion years, but it has a similar fraction of heavy elements. 
The star has prominent starspot activity, with 3% to 14% of the stellar surface covered by areas 575 K cooler than the rest of the photosphere.
A multiplicity survey in 2015 did not detect any stellar companions. The star was named Anadolu in 2019 by Turkish astronomers as part of the "nameexoworlds" contest.
Planetary system.
In 2012 a transiting hot Jupiter planet, WASP-52b, was detected in a tight, circular orbit. The planet was named Gokturk by Turkish astronomers in December 2019. Its equilibrium temperature is and its orbit is well aligned with the equatorial plane of the star, the misalignment being 5.47°.
A transmission spectrum taken in 2020 has revealed the presence of H, Na and K, although the Na and K lines may be attributable to volcanically active moons of the gas giant, not the planet itself. The atmosphere has no high winds and relatively low-lying clouds, indicating it is not significantly enriched by heavy elements. No signs of the planetary atmosphere escaping to space were detected.
