Features
WASP-60 was discovered using the Hipparcos orbital observatory during the Tycho project. The official opening of the star was made in 1997 as part of the publication of the Tycho catalog. The star name in this catalog is TYC 2767-1746-1 . At present, the WASP-60 name, given by a team of researchers from the SuperWASP project, is more common .
WASP-60 is a star of 12 visible magnitude. It was previously believed that this is a yellow dwarf [1] , but further observations have shown [4] that the star has a different spectral class : it is a yellow-white dwarf of class F9. Its mass and radius are 1.07 and 1.14 solar, respectively. The surface temperature of the star is approximately equal to 6105 Kelvin , it makes one revolution around its axis in more than 20 days. The WASP-60 is 3.6 billion years old.
Planet System
In 2011, a group of astronomers working as part of the SuperWASP program announced the discovery [5] of the planet WASP-60 b in the system. It is a hot gas giant with an effective temperature of 1320 Kelvin. Its mass is equal to 1.225 masses of Jupiter. [4] The planet turns at a distance of 0.05 AU from the parent star, making a complete revolution in more than four days. The discovery of the planet was accomplished by the transit method .
