ExEP Exo-Earth yield of a 6 m space telescope in the near-infrared SPIE Proceedings Paper

The search for biosignatures with the future Habitable Worlds Observatory requires high quality spectra over a broad wavelength range and of sufficient signal-to-noise. In this paper, we extend previous exoplanet yields to include wavelengths from 200 nm to 2 microns. Because the IWA for coronagraphs is proportional to wavelength, the achievable spectral coverage will be different for every planet detected. We present the spectral coverage achieved across individual target stars, as well as the ensemble target set, for three architectures (coronagraph, starshade, and hybrid) and include the cumulative exposure time required to reach target depletion for each sub-band
