Description:
Extrasolar giant planets (EGP) in a close-in orbit undergo extreme irradiation by their host star. Emission of H$_{3}^{+}$ is expected to support the stabilization of the planetary atmosphere, since the ion radiates in the near-infrared (NIR) and thereby cools the upper layers of the atmosphere. The simulations of H$_{3}^{+}$ emission from hot Jupiter planets differ in their predicted strengths by several orders of magnitude. H$_{3}^{+}$ emissions from EGP atmospheres have not been detected yet. Previous to this study, only a few other attempts for the observation of H$_{3}^{+}$ from hot Ju...
