HATS-8b is a low density transiting super-Neptune discovered as part of the HATSouth project. The planet orbits its solar-like G-dwarf host (V = , = K) with a period of days. HATS-8b is the third lowest-mass transiting exoplanet to be discovered from a wide-field ground-based search, and with a mass of it is approximately halfway between the masses of Neptune and Saturn. However, HATS-8b has a radius of , resulting in a bulk density of just . The metallicity of the host star is super-solar ( =...[Show more]
