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… 
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.
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 Atacama Large Millimeter/submillimeter Array (ALMA)
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 ∼1.44 au and a minimum mass of about , Proxima c is a prime direct imaging target for atmospheric
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 as
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.
No Transits of Proxima Centauri Planets in High-Cadence TESS Data
Proxima Centauri is our nearest stellar neighbor and one of the most well-studied stars in the sky. In 2016, a planetary companion was detected through radial velocity measurements. Proxima Centauri
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.”
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 elemental

On the Orbital Inclination of Proxima Centauri b
The field of exoplanetary science has seen discovery rates increase dramatically over recent years, due largely to the data from the Kepler mission. Even so, individual discoveries of planets


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.

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.
Red Optical Planet Survey: a new search for habitable earths in the southern sky
We present the first results from our Red Optical Planet Survey to search for low-mass planets orbiting late-type dwarfs (M5.5V–M9V) in their habitable zones. Our observations with the red arm of the

The inner edge of the habitable zone for synchronously rotating planets around low-mass stars using general circulation models
Terrestrial planets at the inner edge of the habitable zone (HZ) of late-K and M-dwarf stars are expected to be in synchronous rotation, as a consequence of strong tidal interactions with their host
