Radial velocity measurements of stellar reflex motion have revealed many extrasolar planets, but gaps in the observations produce aliases, spurious frequencies that are frequently confused with the planets' orbital frequencies. In the case of Gl 581 d, the distinction between an alias and the true frequency was the distinction between a frozen, dead planet and a planet possibly hospitable to life. To improve the characterization of planetary systems, we describe how aliases originate and… Expand
Aliasing in the Radial Velocities of YZ Ceti: An Ultra-short Period for YZ Ceti c?
Mid-to-late M stars are opportunistic targets for the study of low-mass exoplanets in transit because of the high planet-to-star radius ratios of their planets. Recent studies of such stars haveExpand
SIX PLANETS ORBITING HD 219134
We present new, high-precision Doppler radial velocity (RV) data sets for the nearby K3V star HD 219134. The data include 175 velocities obtained with the HIRES Spectrograph at the Keck I Telescope,Expand
The 55 Cnc system reassessed
Orbiting a bright, nearby star the 55 Cnc system offers a rare opportunity to study a multiplanet system that has a wide range of planetary masses and orbital distances. Using two decades ofExpand
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
Three Super-Earths Orbiting HD 7924
We report the discovery of two super-Earth mass planets orbiting the nearby K0.5 dwarf HD 7924 which was previously known to host one small planet. The new companions have masses of 7.9 and 6.4Expand
THE LICK-CARNEGIE SURVEY: FOUR NEW EXOPLANET CANDIDATES
We present new precise HIRES radial velocity (RV) data sets of five nearby stars obtained at Keck Observatory. HD 31253, HD 218566, HD 177830, HD 99492, and HD 74156 are host stars of spectralExpand
Tidal Dissipation and Eccentricity Pumping: Implications for the Depth of the Secondary Eclipse of 55 Cnc e
Aims. We use the super Earth 55 Cnc e as a case study to address an observable effect of tidal heating. This transiting short-period planet belongs to a compact multiple system with massive planets.Expand
The CARMENES search for exoplanets around M dwarfs
The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets. The orbital period of each planet is the subject of discussion in the literature due to strong aliasing inExpand
AliasFinder: A Python script to search for the true planetary frequency within radial velocity data
TLDR
The RV method is the second most successful method and the first one to find exoplanets, but gaps in the observations can result in strong aliases, an effect where two signals are almost indistinguishable when sampled. Expand
Origin and detectability of co-orbital planets from radial velocity data
We analyze the possibilities of detection of hypothetical exoplanets in coorbital motion from synthetic radial velocity (RV) signals, taking into accoun t different types of stable planarExpand
