A re-analysis of Gliese 581 HARPS and HIRES precision radial velocity data was carried out with a Bayesian multiplanet Kepler periodogram (from one to six planets) based on a fusion Markov chain Monte Carlo algorithm. In all cases, the analysis included an unknown parametrized stellar jitter noise term. For the HARPS data set, the most probable number of planetary signals detected is five with a Bayesian false alarm probability of 0.01. These include the 3.1498 ± 0.0005, 5.3687 ± 0.0002, 12.927… Expand
Evidence for nine planets in the HD 10180 system
Aims. We re-analyse the HARPS radial velocities of HD10180 and calculate the probabilities of models with differing numbers of periodic signals in the data. We test the significance of the sevenExpand

GJ 581 update: Additional evidence for a Super-Earth in the habitable zone
ties We present an analysis of the significantly expanded HARPS 2011 radial velocity data set for GJ 581 that was presented by Forveille et al. (2011). Our analysis reaches substantially differentExpand
Dynamical stability of the Gliese 581 exoplanetary system
Using numerical methods we investigate the dynamical stability of the Gliese 581 exoplanetary system. The system is known to harbour four planets (b-e). The existence of another planet (g) in theExpand
Fast Bayesian inference for exoplanet discovery in radial velocity data
Inferring the number of planets $N$ in an exoplanetary system from radial velocity (RV) data is a challenging task. Recently, it has become clear that RV data can contain periodic signals due toExpand
The Lick-Carnegie exoplanet survey: Gliese 687 b—A Neptune-mass planet orbiting a nearby red dwarf
Precision radial velocities from the Automated Planet Finder (APF) and Keck/HIRES reveal an Msin (i) = 18 ± 2 M{sub ⊕} planet orbiting the nearby M3V star GJ 687. This planet has an orbital period PExpand
A search for transits of GJ 581e and characterization of the host star variability using MOST space telescope photometry
The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined forExpand

A new apodized Keplerian (AK) model is proposed for the analysis of precision radial velocity (RV) data to model both planetary and stellar activity (SA) induced RV signals. A symmetrical GaussianExpand
Signals embedded in the radial velocity noise - Periodic variations in the τ Ceti velocities
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'.Expand
