The Yellow Skies and Extreme Bloated Radius of WASP-79b
Deep within the southern constellation of Eridanus, approximately 810 light-years from Earth, resides one of the most physically extreme gas giants ever analyzed by modern astrophysics. Designated WASP-79b , this planet belongs to the extreme class of exoplanets known as " Hot Jupiters "—massive gaseous worlds that orbit in precariously close proximity to their parent stars. Discovered in 2012 by the Wide Angle Search for Planets (WASP) consortium, this world has challenged long-held models of planetary formation, atmospheric chemistry, and radiative equilibrium. With a mass roughly 90 percent of Jupiter 's but a volume that stretches to nearly twice Jupiter's size, WASP-79b stands as a archetype of "bloated" or low-density gas giants, offering an unprecedented window into the physics of extreme solar irradiance. The primary star of this system, WASP-79 (also cataloged as CD-30 1812), is an F-type main-sequence star. Hotter, larger, and significantly mor...
