What could be observed in the case of Super-Ios and Hyper-Ios? Danielle Briot & Jean Schneider We study the case of a Earth, or a Super-Earth with a volcanic activity as strong as Io’s. We call such an object a Super-Io and a Hyper-Io in the case of a Super-Earth. -In case of a transit, sulphur dioxid could be observed in the atmosphere -These objects are very good candidates for secondary transits observations, specially at 3.5  m, and the hot spots corresponding to volcanoes could be detected in the first part and the last part of the secondary transit. - These objects could be easily observed by imaging in the infrared, specially in a case of a cool star.
