Exoplanet Exploration Program Analysis Group (ExoPAG) Report to Paul Hertz Regarding Large Mission Concepts to Study for the 2020 Decadal Survey
B. Scott Gaudi, Eric Agol, Daniel Apai +36
This is a joint summary of the reports from the three Astrophysics Program Analysis Groups (PAGs) in response to the "Planning for the 2020 Decadal Survey" charge given by the Astr…
Discovery of a low-mass companion around HR3549
Dimitri Mawet, Trevor David, Michael Bottom +7
We report the discovery of a low-mass companion to HR3549, an A0V star surrounded by a debris disk with a warm excess detected by WISE at 22 m ( significance). We imaged HR…
Characterizing Rocky and Gaseous Exoplanets with 2-meter Class Space-based Coronagraphs
Tyler D. Robinson, Karl R. Stapelfeldt, Mark S. Marley
Several concepts now exist for small, space-based missions to directly characterize exoplanets in reflected light. Here, we develop an instrument noise model suitable for studying…
Lower Limits on Aperture Size for an ExoEarth-Detecting Coronagraphic Mission
Christopher C. Stark, Aki Roberge, Avi Mandell +4
The yield of Earth-like planets will likely be a primary science metric for future space-based missions that will drive telescope aperture size. Maximizing the exoEarth candidate y…
Radial Velocity Prospects Current and Future: A White Paper Report prepared by the Study Analysis Group 8 for the Exoplanet Program Analysis Group (ExoPAG)
Peter Plavchan, Dave Latham, Scott Gaudi +17
[Abridged] The Study Analysis Group 8 of the NASA Exoplanet Analysis Group was convened to assess the current capabilities and the future potential of the precise radial velocity (…
Target Selection for the LBTI Exozodi Key Science Program
Alycia J. Weinberger, Geoff Bryden, Grant M. Kennedy +13
The Hunt for Observable Signatures of Terrestrial planetary Systems (HOSTS) on the Large Binocular Telescope Interferometer will survey nearby stars for faint emission arising from…
