WASP-49b is a hot-Jupiter exoplanet orbiting the Sun-like star WASP-49 A. It is about 40% the mass of Jupiter and has an equilibrium temperature of 1369±39 K. [1] The planet was discovered to be surrounded by a sodium envelope, which could indicate the presence of a potential exomoon. [2]
WASP-49b was found to possess an extensive sodium envelope in 2017. [2] Additionally, the Hubble Space Telescope found clear absorption features in near-UV light, indicating the presence of magnesium and iron. These metals may not be gravitationally bound to the planet, but could be magnetically confined to it. [3] WASP-49b has an equilibrium temperature of 1369±39 K, making it a hot-Jupiter or hot-Saturn planet.
The existence of a sodium envelope around WASP-49b could be explained by the presence of a volcanically active, Io-like exomoon. [4] However, this idea remains speculative. Additionally, 3 sodium "booms" were detected over a period of 40 minutes each, as well as Doppler-shifts of the planet indicative of a third body orbiting WASP-49b with a period of 8 hours, near the planet's Roche limit.
