Abstract
The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) will be a thermal infrared high-contrast integral field spectrograph located at the W.M. Keck Observatory. SCALES will detect and characterize planets currently inaccessible to detailed study by operating at mid-infrared (2-5 µm) wavelengths and leveraging integral-field spectroscopy to distinguish exoplanet radiation from residual starlight. SCALES’ current medium resolution mode (R≈3,500-7,000) will enable investigations of planet accretion processes, though in the future, SCALES will be upgraded with additional higher resolution gratings. We present the designs of custom high-resolution observing modes for SCALES that differentiate accretion properties and geometries from simulated observations of accreting protoplanets. We arrive at these designs by generating a large grid of modeled hydrogen emission line profiles and ray-trace them with SCALES’ end-to-end simulator, scalessim, to produce mock datasets. In this proceeding, we describe the accretion parameter constraining power gained when observing with these specialized accretion-tracing modes over the baseline medium-resolution modes of SCALES.
