At a distance of 1.295 parsecs, the red dwarf Proxima Centauri (α Centauri C, GL 551, HIP 70890 or simply Proxima) is the Sun’s closest stellar neighbour and one of the best-studied low-mass stars. It has an effective temperature of only around 3,050 kelvin, a luminosity of 0.15 per cent of that of the Sun, a measured radius of 14 per cent of the radius of the Sun and a mass of about 12 per cent of the mass of the Sun. Although Proxima is considered a moderately active star, its rotation period… Expand

ALMA Discovery of Dust Belts Around Proxima Centauri
Proxima Centauri, the star closest to our Sun, is known to host at least one terrestrial planet candidate in a temperate orbit. Here we report the ALMA detection of the star at 1.3 mm wavelength andExpand
A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU
It is shown that the existence of the planet can be ascertained, and its true mass can be determined with high accuracy, by combining Gaia astrometry and radial velocities, and the candidate planet represents a challenge for the models of super-Earth formation and evolution. Expand
An Earth-like Stellar Wind Environment for Proxima Centauri c
A new planet has been recently discovered around Proxima Centauri. With an orbital separation of $\sim$$1.44$ au and a minimum mass of about $7$ $M_{\oplus}$, Proxima c is a prime direct imagingExpand
Proxima’s orbit around α Centauri
Proxima and α Centauri AB have almost identical distances and proper motions with respect to the Sun. Although the probability of such similar parameters is, in principle, very low, the question asExpand
Astronomy: Earth-like planet around Sun's neighbour
An analysis of previously obtained observations and new Doppler data from instruments at the European Southern Observatory reveals the presence of a small planet with a minimum mass of 1.3 Earth masses orbiting Proxima Centauri, the nearest star to the Sun. Expand
The Space Weather of Proxima Centauri b
A planet orbiting in the "habitable zone" of our closest neighboring star, Proxima Centauri, has recently been discovered, and the next natural question is whether or not Proxima b is "habitable".Expand
The habitability of Proxima Centauri b. I. Irradiation, rotation and volatile inventory from formation to the present
Proxima b is a planet with a minimum mass of 1.3 MEarth orbiting within the habitable zone (HZ) of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we investigate aExpand
A temperate rocky super-Earth transiting a nearby cool star
Observations of LHS 1140b, a planet with a radius of 1.4 Earth radii transiting a small, cool star (L HS 1140) 12 parsecs away, measure the mass of the planet to be 6.6 times that of Earth, consistent with a rocky bulk composition, and place an upper limit on the orbital eccentricity. Expand
Characterizing the possible interior structures of the nearby Exoplanets Proxima Centauri b and Ross-128 b
We developed a new numerical model to constrain the interior structure of rocky Exoplanets, and applied it to the nearby planets Proxima Centauri b and Ross-128 b. The recently measured elementalExpand
Magnetic properties of Proxima Centauri b analogues
Abstract The discovery of a planet around the closest star to our Sun, Proxima Centauri, represents a quantum leap in the testability of exoplanetary models. Unlike any other discovered exoplanet,Expand


A Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation
The observation of a multi-chord stellar occultation by Eris on 6 November 2010 is reported, consistent with a spherical shape for Eris, and it is anticipated that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun. Expand
