On the eccentricity of Proxima b
Robert A. Brown
We apply Monte Carlo projection to the radial velocity data set that Anglada Escude et al. (2016) use for the discovery of Proxima b. They find an upper limit to the orbital eccent…
The Lyot Project Direct Imaging Survey of Substellar Companions: Statistical Analysis and Information from Nondetections
Jérémy leconte, Rémi Soummer, Sasha Hinkley +14
The Lyot project used an optimized Lyot coronagraph with Extreme Adaptive Optics at the 3.63m Advanced Electro-Optical System telescope (AEOS) to observe 86 stars from 2004 to 2007…
Photometric Orbits of Extrasolar Planets
Robert A. Brown
We define and analyze the photometric orbit (PhO) of an extrasolar planet observed in reflected light. In our definition, the PhO is a Keplerian entity with six parameters: semimaj…
Science-Operational Metrics and Issues for the "Are We Alone?" Movement
Robert A. Brown
A movement is underway to test the uniqueness of Earth. Sponsored primarily by NASA, it is enlisting talented researchers from many disciplines. It is conceiving new telescopes to…
On the Completeness of Reflex Astrometry on Extrasolar Planets near the Sensitivity Limit
Robert A. Brown
We provide a preliminary estimate of the performance of reflex astrometry on Earth-like planets in the habitable zones of nearby stars. In Monte Carlo experiments, we analyze large…
