Space-based direct imaging provides prospects for detection and spectral characterization of exoplanets at optical and near-infrared wavelengths. Integral field spectrographs (IFS) have been historically baselined for these mission concepts.

New Models of Reflection Spectra for Terrestrial Exoplanets: Present and Prebiotic Earth Orbiting Around Stars of Different Spectral Types
In order to recognize a habitable exoplanet from future observed spectra, we present new model reflected spectra and geometric albedo for modern and prebiotic (3.9 Ga) Earth-like exoplanets orbiting within […]

Spectroscopic Mapping Of Io’s Surface With HST/STIS: SO2 Frost, Sulfur allotropes, And Large-scale Compositional Patterns
Io’s intense volcanic activity results in one of the most colorful surfaces in the solar system. Ultraviolet and visible-wavelength observations of Io are critical to uncovering the chemistry behind its […]

A Reexamination of Phosphorus and Chlorine Depletions in the Diffuse Interstellar Medium
We present a comprehensive examination of interstellar P and Cl abundances based on an analysis of archival spectra acquired with the Space Telescope Imaging Spectrograph of the Hubble Space Telescope […]
