HAT-P-6

HAT- P -6 is a star system in the constellation Andromeda. The system is of the earth about 650 light-years (200 parsecs ) away, the star is of spectral type F, which means that it is larger and hotter than our sun. The apparent magnitude of 10.5 m is not sufficient to account for the star with the naked eye can, the absolute magnitude is 4.0 M, which is much brighter compared to the Sun ( 4.83 M). Other names for the star - depending on the catalog - are GSC 03239-00992, 2MASS J23390581 4227575, TYC 3239-992-1.

Planetary system

The companion of HAT- P-6 with the systematic name HAT- P- 6b is passing from our perspective before its star, resulting in a slight drop in the brightness of the star, so that the existence and orbital period of the object can be detected ( transit method ). HAT- P- 6b was discovered on 15 October 2007, has a mass which is by 5.7 % higher than that of Jupiter, has a 33% larger compared to the Jupiter radius and a density of 0.45 g / cm ³. The low density is caused by the intense heat radiation the planet receives from its sun and lets him expand. Therefore, the planet to the category of "hot Jupiter", the hot planet, Jupiter is one very similar. For one orbit around its star, the planet takes 3.85 days and is only 0.05235 AU from its sun.
