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 […]

A Terrestrial Planet Candidate in a Temperate Orbit Around Proxima Centauri
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 neighbor and one of the […]

Geomagnetic Properties of Proxima Centauri b Analogues
The recent discovery of a planet around the closest star, Proxima Centauri, could represent a quantum leap on the testability of models in exoplanet sciences. Unlike any other discovered exoplanet, […]

The Habitability of Proxima Centauri b: Environmental States and Observational Discriminants
Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star’s habitable zone, multiple […]

Calculations of Periodicity From Hα Profiles of Proxima Centauri
We investigate retrieval of the stellar rotation signal for Proxima Centauri. We make use of high-resolution spectra taken with uves and harps of Proxima Centauri over a 13-year period as […]

Could Proxima Centauri b Really Be Habitable?
The world’s attention is now on Proxima Centauri b, a possibly Earth-like planet orbiting the closest star, 4.22 light-years away. The planet’s orbit is just right to allow liquid water […]

Prospects for Characterizing the Atmosphere of Proxima Centauri b
The newly detected Earth-mass planet in the habitable zone of Proxima Centauri could potentially host life – if it has an atmosphere that supports surface liquid water. We show that […]

Tutorial Models of the Climate and Habitability of Proxima Centauri b
Proxima Centauri b, an Earth-size planet in the habitable zone of our nearest stellar neighbour, has just been discovered. A theoretical framework of synchronously rotating planets, in which the risk […]

The Habitability of Proxima Centauri b I: Evolutionary Scenarios
We analyze the evolution of the potentially habitable planet Proxima Centauri b to identify environmental factors that affect its long-term habitability. We consider physical processes acting on size scales ranging […]
