Overview and Reassessment of Noise Budget of Starshade Exoplanet Imaging
Renyu Hu, Doug Lisman, Stuart Shaklan +3
High-contrast imaging enabled by a starshade in formation flight with a space telescope can provide a near-term pathway to search for and characterize temperate and small planets o…
No escaping helium from 55 Cnc e
Michael Zhang, Heather A. Knutson, Lile Wang +3
We search for escaping helium from the hot super Earth 55 Cnc e by taking high-resolution spectra of the 1083 nm line during two transits using Keck/NIRSPEC. We detect no helium ab…
Multi-orbital-phase and multi-band characterization of exoplanetary atmospheres with reflected light spectra
Mario Damiano, Renyu Hu, Sergi R. Hildebrandt
Direct imaging of widely separated exoplanets from space will obtain their reflected light spectra and measure atmospheric properties. Previous calculations have shown that a chang…
Photochemistry of Anoxic Abiotic Habitable Planet Atmospheres: Impact of New HO Cross-Sections
Sukrit Ranjan, Edward W. Schwieterman, Chester Harman +4
We present a study of the photochemistry of abiotic habitable planets with anoxic CO-N atmospheres. Such worlds are representative of early Earth, Mars and Venus, and analo…
ExoReL: A Bayesian Inverse Retrieval Framework For Exoplanetary Reflected Light Spectra
Mario Damiano, Renyu Hu
The high-contrast imaging technique is meant to provide insight into those planets orbiting several astronomical units from their host star. Space missions such as WFIRST, HabEx, a…
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +183
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficient…
