NASA Exoplanet Exploration Program (ExEP) Science Gap List
Karl Stapelfeldt, Eric Mamajek
The Exoplanet Exploration Program (ExEP) is chartered by the NASA Astrophysics Division to carry out science, research, and technology tasks that advance NASA's science goals for e…
Cross-Model Validation of Coronagraphic Exposure Time Calculators for the Habitable Worlds Observatory: A Report from the Exoplanet Science Yield sub-Working Group
Christopher C. Stark, Sarah Steiger, Armen Tokadjian +9
Estimating the exoplanet scientific productivity of the Habitable Worlds Observatory requires estimating science exposure times. From exoplanet yields to spectral retrievals, expos…
Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater
Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30
Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…
The Roman coronagraph community participation program: observation planning
Schuyler G. Wolff, Jason Wang, Karl Stapelfeldt +18
The Coronagraphic Instrument onboard the Nancy Grace Roman Space Telescope is an important stepping stone towards the characterization of habitable, rocky exoplanets. In a technolo…
Current laboratory performance of starlight suppression systems, and potential pathways to desired Habitable Worlds Observatory exoplanet science capabilities
Bertrand Mennesson, Ruslan Belikov, Emiel Por +34
We summarize the current best polychromatic (10 to 20 % bandwidth) contrast performance demonstrated in the laboratory by different starlight suppression approaches and systems des…
NASA Exoplanet Exploration Program (ExEP) Mission Star List for the Habitable Worlds Observatory (2023)
Eric Mamajek, Karl Stapelfeldt
The Astro 2020 Decadal Survey "Pathways to Discovery in Astronomy and Astrophysics for the 2020s" has recommended that "after a successful mission and technology maturation program…
