Forever alone? : Testing single eccentric planetary systems for multiple companions
(2013-09)
Determining the orbital eccentricity of an extrasolar planet is critically important for understanding the system's dynamical environment and history. However, eccentricity is often poorly determined or entirely mischaracterized ...
Observing Strategies for the Detection of Jupiter Analogs
(2013-04)
To understand the frequency, and thus the formation and evolution, of planetary systems like our own solar system, it is critical to detect Jupiter-like planets in Jupiter-like orbits. For long-term radial-velocity monitoring, ...
Signals embedded in the radial velocity noise: Periodic variations in the tau Ceti velocities
(2013-03)
Context. The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a combination of instrument precision, lack of data, and “jitter”. Jitter is a general term ...
