The Molten Metallic Surface of Ultra-Short Period Super-Earth K2-106b
Orbiting its host star at a blistering proximity, K2-106b represents one of the most extreme examples of a short-period super-Earth yet documented by current observational arrays. This world, situated within the K2 mission survey area, is defined by its rapid orbital transit of just over thirteen hours, placing it in a regime of extreme thermal radiation that dictates its entire geological character. The physical structure of K2-106b is characterized by a high bulk density , suggesting a massive iron-nickel core draped in a thin, scorched mantle of refractory minerals . Unlike larger gas-dominated worlds, this celestial body maintains a rigid, solidified crust that experiences relentless bombardment from the host star's high-energy emissions. The intense heat effectively strips away any volatile gases, leaving behind a bare, irradiated surface of superheated rock and...
