Direct Imaging Spectroscopy

Choosing Between Transmission, Emission, and Direct-Imaging Spectroscopy for Exoplanet Atmospheres

This guide compares transmission, emission, and direct-imaging spectroscopy for exoplanet atmospheric characterization, detailing their strengths, limitations, and optimal use cases. It also explains how High-Resolution Spectroscopy (HRS) enhances these methods by resolving individual spectral lines, aiding in the detection of molecules and atmospheric dynamics.
