Pathway Toward a Mid-Infrared Interferometer for the Direct Characterization of Exoplanets

Abstract

We recognize the need for the characterization of exoplanets in reflected light in the visible and in the IR termal emission. But for the thermal infrared we also recognize the difficulty of an interferometric nuller We nevertheless endorse the need for future interferometers. We propose a new, realistic, pathway to satisfy both goals, thermal infrared studies and interferometric architectures.
