Characterizing the Habitable Zones of Exoplanetary Systems with a Large Ultraviolet/Visible/Near-IR Space Observatory
Kevin France, Evgenya Shkolnik, Jeffrey Linsky +32
Understanding the surface and atmospheric conditions of Earth-size, rocky planets in the habitable zones (HZs) of low-mass stars is currently one of the greatest astronomical endea…
The Habitable-Zone Planet Finder: A Stabilized Fiber-Fed NIR Spectrograph for the Hobby-Eberly Telescope
Suvrath Mahadevan, Lawrence Ramsey, Chad Bender +12
We present the scientific motivation and conceptual design for the recently funded Habitable-zone Planet Finder (HPF), a stabilized fiber-fed near-infrared (NIR) spectrograph for t…
Discovering and Characterizing the Planetary Systems of Nearby Stars: The scientific need for medium aperture space coronagraph observations
Tom Greene, Kerri Cahoy, Olivier Guyon +7
Significant advances in the discovery and characterization of the planetary systems of nearby stars can be accomplished with a moderate aperture high performance coronagraphic spac…
Exploring Other Worlds: Science Questions for Future Direct Imaging Missions (EXOPAG SAG15 Report)
Daniel Apai, Nicolas Cowan, Ravikumar Kopparapu +30
The NASA Exoplanet Exploration Program's SAG15 group has solicited, collected, and organized community input on high-level science questions that could be addressed with future dir…
Testing the Early Mars H2-CO2 Greenhouse Hypothesis with a 1-D Photochemical Model
Natasha Batalha, Shawn D. Domagal-Goldman, Ramses Ramirez +1
A recent study by Ramirez et al. (2014) demonstrated that an atmosphere with 1.3-4 bar of CO2 and H2O, in addition to 5-20% H2, could have raised the mean annual and global surface…
Telescope to Observe Planetary Systems (TOPS): a high throughput 1.2-m visible telescope with a small inner working angle
Olivier Guyon, James R. P. Angel, Charles Bowers +20
The Telescope to Observe Planetary Systems (TOPS) is a proposed space mission to image in the visible (0.4-0.9 micron) planetary systems of nearby stars simultaneously in 16 spectr…
