We present results of simulations of the climate of the newly discovered planet Proxima Centauri B, performed using the Met Office Unified Model (UM). We examine the responses of both […]

Is Proxima Centauri b Habitable? – A Study of Atmospheric Loss
We address the important question of whether the newly discovered exoplanet, Proxima Centauri b (PCb), is capable of retaining an atmosphere over long periods of time. This is done by […]

On The Eccentricity of Proxima b
We apply Monte Carlo projection to the radial velocity data set that Anglada Escude et al. (2016) use for the discovery of Proxima b. They find an upper limit to […]

How Far Are Extraterrestrial Life and Intelligence After Kepler?
The Kepler mission has shown that a significant fraction of all stars may have an Earth-size habitable planet. A dramatic support was the recent detection of Proxima Centauri b. Using […]

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 orbiting […]

Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Centauri using […]

Magnetic cycles in a Dynamo Simulation of Fully Convective M-star Proxima Centauri
The recent discovery of an Earth-like exoplanet around Proxima Centauri has shined a spot light on slowly rotating fully convective M-stars. When such stars rotate rapidly (period ≲20 days), they […]

Possible Internal Structures and Compositions of Proxima Centauri b
We explore the possible Proxima Centauri b’s interiors assuming the planet belongs to the class of dense solid planets (rocky with possible addition of water) and derive the corresponding radii. […]

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 […]

The Pale Green Dot: A Method to Characterize Proxima Centauri b using Exo-Aurorae
We examine the feasibility of detecting auroral emission from the potentially habitable exoplanet Proxima Centauri b. This planet’s active, late-type M dwarf host makes detection of aurorae more favorable than […]
