We use more than a decade of radial-velocity measurements for A, B, and Proxima Centauri from the High Accuracy Radial Velocity Planet Searcher, CTIO High Resolution Spectrograph, and the Ultraviolet and Visual Echelle Spectrograph to identify the and orbital periods of planets that could have been detected if they existed. At each point in a mass–period grid, we sample a simulated, Keplerian signal with the precision and cadence of existing data and assess the probability that the signal could… 

The Test Case of HD 26965: Difficulties Disentangling Weak Doppler Signals from Stellar Activity

We report the discovery of a radial velocity signal that can be interpreted as a planetary-mass candidate orbiting the K dwarf HD 26965, with an orbital period of 42.364 ± 0.015 days, or

Transit Search for Exoplanets around Alpha Centauri A and B with ASTERIA

Alpha Centauri is a triple star system with two Sun-like stars, α Cen A (V = 0.01) and B (V = 1.33), and a third fainter red dwarf star, Proxima Centauri. Most current transit missions cannot produce

Precision Millimeter Astrometry of the α Centauri AB System

Alpha Centauri A is the closest solar-type star to the Sun and offers the best opportunity to find and ultimately to characterize an Earth-sized planet located in its habitable zone. Here, we

An Excess of Jupiter Analogs in Super-Earth Systems

We use radial velocity (RV) observations to search for long-period gas giant companions in systems hosting inner super-Earth (1–4 R⊕, 1–10 M⊕) planets to constrain formation and migration scenarios

Searching for Planets Orbiting α Cen A with the James Webb Space Telescope

α Centauri A is the closest solar-type star to the Sun and offers an excellent opportunity to detect the thermal emission of a mature planet heated by its host star. The MIRI coronagraph on the James

The two solar-like stars α Cen A and B have long served as cornerstones for stellar physics in virtue of their immediate proximity, association in a visual binary, and masses that bracket that of the

Exomoons in Systems with a Strong Perturber: Applications to α Cen AB

The presence of a stellar companion can place constraints on occurrence and orbital evolution of satellites orbiting exoplanets, i.e., exomoons. In this work we revise earlier orbital stability

Imaging low-mass planets within the habitable zone of α Centauri

Sensitivity to warm sub-Neptune-sized planets throughout much of the habitable zone of α Centauri A is demonstrated, an order of magnitude more sensitive than state-of-the-art exoplanet imaging mass detection limits.

PEXO: A Global Modeling Framework for Nanosecond Timing, Microarcsecond Astrometry, and μm s−1 Radial Velocities

The ability to make independent detections of the signatures of exoplanets with complementary telescopes and instruments brings a new potential for robust identification of exoplanets and precision

Orbital Stability of Circumstellar Planets in Binary Systems

Planets that orbit only one of the stars in stellar binary systems (i.e., circumstellar) are dynamically constrained to a limited range of orbital parameters, and understanding conditions on their



Formation and Detectability of Terrestrial Planets around α Centauri B

We simulate the formation of planetary systems around α Centauri B. The N-body accretionary evolution of a Σ ∝ r−1 disk populated with 400-900 lunar-mass protoplanets is followed for 200 Myr. All

Planet formation in the habitable zone of α Centauri B

Recent studies have shown that α Centauri B might be, from an observational point of view, an ideal candidate for the detection of an Earth-like planet in or near its habitable zone (0.5-0.9au). We

Formation and Detectability of Terrestrial Planets around α

We simulate the formation of planetary systems around α Centauri B. The N-body accretionary evolution of a Σ ∝ r disk populated with 400-900 lunarmass protoplanets is followed for 200 Myr. All

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'.

Searching for Earth-mass planets around α Centauri: precise radial velocities from contaminated spectra

Abstract This work is part of an ongoing project which aims to detect terrestrial planets in our neighbouring star system α Centauri using the Doppler method. Owing to the small angular separation

No planet for HD 166435

The G0 V star HD 166435 has been observed by the ber-fed spectrograph ELODIE as one of the targets in the large extra-solar planet survey that we are conducting at the Observatory of Haute-Provence.


We present an analysis of the publicly available HARPS radial velocity (RV) measurements for α Cen B, a star hosting an Earth-mass planet candidate in a 3.24 day orbit. The goal is to devise robust

Are Proxima and α Centauri Gravitationally Bound?

Using the most recent kinematic and radial velocity data in the literature, we calculate the binding energy of Proxima Centauri relative to the center of mass of the α Centauri system. When we adopt

Ultra-High-Precision Velocity Measurements of Oscillations in α Centauri A

We have made differential radial velocity measurements of the star α Centauri A using two spectrographs, the UV-Visual Echelle Spectrograph (UVES) and the University College London Echelle

Ghost in the time series: no planet for Alpha Cen B

We re-analyse the publicly available radial velocity (RV) measurements for Alpha Cen B, a star hosting an Earth-mass planet candidate, Alpha Cen Bb, with 3.24 day orbital period. We demonstrate that
