Irradiance source for exoplanet atmospheric spectra
… setting through examination of exoplanet atmospheric responses to photosynthetic bacteria under simulations of the irradiance conditions of a planet’s host star. The goal of this project was to design and construct a second-generation apparatus at Eastern Michigan University. The team …

Simulation and testing of wavefront reconstruction algorithms for the deformable mirror (DeMi) cubesat
… necessary to directly image them and study their atmospheric spectra. Especially of interest are Earth-like planets, but they are typically outshined by their host stars by a factor of 10₁₀, meaning high-contrast imaging is required to see them. Coronagraphs are typically used to block the …

The Observational Diversity of sub-Neptunes
… of these most-common exoplanets with space-based atmospheric spectroscopy, as well as models of their atmospheres including the effects of clouds and hazes. First, I present the near-infrared atmospheric transmission spectrum of the warm Neptune TOI-674 b, observed with the \textit{Hubble} Space …

Bayesian atmospheric retrieval for exoplanets : uniqueness of exoplanet spectra, characterizations of super-earths, and evaluations of dedicated space telescope designs
… observations of exoplanets to infer the planet's atmospheric compositions, the surface pressures, and the presences of clouds or hazes. I identify what can unambiguously be determined about the atmospheres of exoplanets by applying the retrieval method to sets of synthetic observations. The main …

Retrieval of atmospheric properties of extrasolar planets
… HD 209458b. For each planet, we compute - 107 atmospheric spectra on a grid in the parameter space, and report contours of the error surface, given the data. For the day-side of HD 189733b, we place constraints on the atmospheric properties based on three different data sets available. Our …
