The Tidal Distortions and Carbon-Rich Atmosphere of Exoplanet WASP-12b
In the constellation Auriga, approximately 1,400 light-years from Earth, orbits one of the most physically extreme planetary bodies ever cataloged by modern astronomy. WASP-12b , a gas giant of the 'Hot Jupiter' class, serves as a premier laboratory for the study of extreme tidal forces and atmospheric chemistry under intense irradiation. Unlike the near-perfect spheres of our own solar system’s gas giants, WASP-12b is visibly distorted. The immense gravitational pull of its host star, a yellow-white F-type star, has stretched the planet into a prolate spheroid —a shape resembling a rugby ball or an egg. This tidal deformation is so pronounced that it marks a threshold in planetary physics where the structural integrity of the body is actively losing the battle against the star's gravity. Discovered in 2008 by the SuperWASP (Wide Angle Search for Planets) survey, WASP-12b orbits at a staggering proximity to its star, completing a full 'year' in just over ...
