Systemic: A Testbed For Characterizing the Detection of Extrasolar Planets. I. The Systemic Console Package

摘要

We present the systemic Console, a new all-in-one, general-purpose softwarepackage for the analysis and combined multiparameter fitting of Doppler radialvelocity (RV) and transit timing observations. We give an overview of thecomputational algorithms implemented in the Console, and describe the toolsoffered for streamlining the characterization of planetary systems. Weillustrate the capabilities of the package by analyzing an updated radialvelocity data set for the HD128311 planetary system. HD128311 harbors a pair ofplanets that appear to be participating in a 2:1 mean motion resonance. We showthat the dynamical configuration cannot be fully determined from the currentdata. We find that if a planetary system like HD128311 is found to undergotransits, then self-consistent Newtonian fits to combined radial velocity dataand a small number of timing measurements of transit midpoints can provide animmediate and vastly improved characterization of the planet's dynamical state.
