HAT-P-14b
HAT-P-14b, officially named Sissi also known as WASP-27b, is an extrasolar planet located approximately away in the constellation of Hercules, orbiting the 10th magnitude F-type [main-sequence star] HAT-P-14. This planet was discovered in 2010 by the HATNet Project using the transit method. It was independently detected by the SuperWASP project.
Host star
The host star is a main-sequence star with the spectral classification F5V and apparent magnitude 9.98, well below the naked-eye visibility limit. It has a mass of, a radius of, and a surface temperature of. The star HAT-P-14 is named Franz.History
The planet HAT-P-14b was named Sissi. The name was selected by Austria as part of the NameExoWorlds campaign for the 100th anniversary of the IAU. The planet was named after the character Sissi in the movie Sissi, who is married to Franz. The role is played by the actress Romy Schneider. The star HAT-P-14 is named Franz.HAT-P-14b was selected as the target object for testing the James Webb [Space Telescope] instruments intended for spectroscopic studies of transiting exoplanets. It was chosen because its high surface gravity should produce a very flat spectrum, regardless of the planet's composition.
