Content

Characteristics

HAT-P-34 is a dwarf F class star. It is brighter, larger, and much younger than our Sun. Its mass and radius are 1.39 and 1.53 solar, respectively. ^[1] The star's luminosity is 3.63 times the solar one. Surface temperature is about 6442 Kelvin . The star's age is estimated at about 1.7 billion years.

Planetary system

In early 2012, a group of astronomers working under the HATNet project announced the discovery ^{[1] of the} planet HAT-P-34 b in the system. This is a typical hot jupiter , having a mass and radius equal to 3.33 and 1.2 Jupiter . The planet turns at a distance of 0.068 a. e. from the parent star, making a full turn in 5.45 days. The effective temperature of the planet is 1520 Kelvin . The discovery was made by the transit method .
