- 요약Planets come in many shapes and sizes from small barren rocks, to Earth-sized planets hosting unique and exotic atmospheres, to massive gas giants many times the size of Jupiter. Despite the great diversity, all planets have at least one thing in common-they are all shaped and influenced by the star which hosts them. The amount of radiation a planet receives in various wavelength regions can have dramatic effects on the composition and evolution of the atmosphere. Particularly important is the high-energy radiation from X-rays to the ultraviolet which penetrate the upper layers of planetary atmospheres, heating the atmosphere and driving photochemistry and atmospheric escape. As exoplanet science continues to grow, especially with the search for habitable worlds, it is crucial to understand the high-energy environment of planet-hosting stars and their influence on atmospheres. In this thesis I present the results of three exoplanet-related far-UV (FUV; 912 λ 1700 ˚A) spectroscopic investigations utilizing suborbital sounding rocket experiments and observations from several space-based observatories. First, I discuss astrophysical instrumentation and technology development in the UV with the assembly and testing of two telescopes for the Far- and Lyman-Ultraviolet Imaging Demonstrator (FLUID) sounding rocket and the third flight of the Suborbital Imaging Spectrograph for Transition-region Irradiance from Nearby Exoplanet host stars (SISTINE) sounding rocket, both designed and built at the University of Colorado, Boulder. FLUID is a rocket-borne UV imaging payload which will combine four telescopes with different UV bandpasses to characterize the distribution of O- and B-type stars in nearby galaxies. SISTINE is a rocket-borne far-UV imaging spectrograph designed to observe stellar emission from the transition region and chromosphere of exoplanet hosting stars and their analogs. I present the results from the third flight of SISTINE, which observed the binary solar-like stars α Centauri A and B. Next, I present my work characterizing 11 exoplanet-hosting FGKM stars which had never been observed in the UV. I use observations with the Hubble Space Telescope, XMM-Newton, and the Chandra X-ray Observatory in combination with empirical models to create spectral energy distributions of each star which have since been used to characterize the atmospheres of several exoplanets, including the first detection of atmospheric photochemistry on an exoplanet with the James Webb Space Telescope. Finally, I present the first far-UV transit spectroscopy of an ultra-hot Jupiter in which we investigate the atmosphere of a massive planet subjected to a particularly extreme far-UV environment.
