The hunt for Earth analogue planets orbiting Sun-like stars has forced the introduction of novel methods to detect signals at, or below, the level of the intrinsic noise of the observations. We present a new global periodogram method that returns more information than the classic Lomb-Scargle periodogram method for radial velocity signal detection. Our method uses the Minimum Mean Squared Error as a framework to determine the optimal number of genuine signals present in a radial velocity… Expand

Statistical methods using hydrodynamic simulations of stellar atmospheres for detecting exoplanets in radial velocity data
This work investigates the possibility of using hydrodynamic simulations of the stellar convection in the detection process to control exoplanet detection claims. Expand
Filtering out activity-related variations from radial velocities in a search for low-mass planets
Variations related to stellar activity and correlated noise can prevent the detections of low-amplitude signals in radial velocity data if not accounted for. This can be seen as the greatest obstacleExpand
Radial velocity data analysis with compressed sensing techniques
We present a novel approach for analysing radial velocity data that combines two features: all the planets are searched at once and the algorithm is fast. This is achieved by utilizing compressedExpand
The Radial Velocity Method for the Detection of Exoplanets
The radial velocity (RV) method has provided the foundation for the research field of exoplanets. It created the field by discovering the first exoplanets and then blazed a trail by detecting overExpand
The SOPHIE search for northern extrasolar planets
Periodic radial velocity variations in the nearby M-dwarf star Gl 411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish between a 12.95-dayExpand
A novel period estimation method for X-ray pulsars based on frequency subdivision
A new method based on frequency subdivision and the continuous Lomb periodogram (CLP) is proposed to improve precision of period estimation using short-time observation data and performs better than efsearch (a period estimation method of HEAsoft) with lower computational complexity. Expand

We report constraints on the three-dimensional orbital architecture for all four planets known to orbit the nearby M dwarf Gliese 876 based solely on Doppler measurements and demanding long-termExpand
Proxima Centauri b is not a transiting exoplanet
We report Spitzer Space Telescope observations during predicted transits of the exoplanet Proxima Centauri b. As the nearest terrestrial habitable-zone planet we will ever discover, any potentialExpand
Discovering New Worlds: A review of signal processing methods for detecting exoplanets from astronomical radial velocity data [Applications Corner]
Exoplanets, short for extra solar planets, are planets outside the authors' solar system that are small enough so they cannot burn deuterium in their cores, yet large enough that they are not so-called dwarf planets like Pluto. Expand
New planetary systems from the Calan-Hertfordshire Extrasolar planet search
We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as part of theExpand


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
