Simulating medium-spectral-resolution exoplanet characterization with SCALES angular/reference differential imaging Open
SCALES (Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy) is a 2 - 5 micron high-contrast lenslet-based integral field spectrograph (IFS) designed to characterize exoplanets and their atmospheres. The SCALES medium-spectra…

The Kinematics and Excitation of Infrared Water Vapor Emission from Planet-forming Disks: Results from Spectrally Resolved Surveys and Guidelines for JWST Spectra Open
This work presents ground-based spectrally resolved water emission at R = 30,000–100,000 over infrared wavelengths covered by the JWST (2.9–12.8 μ m). Two new surveys with iSHELL and the VISIR are combined with previous spectra from the CR…

Early volatile depletion on planetesimals inferred from C–S systematics of iron meteorite parent bodies Open
Significance Habitable rocky worlds require a supply of essential volatile elements (C, H, N, and S). These are plentiful in early solar systems but depleted during processes leading to planet formation. Here, evidence for loss during diff…
