The nearby exoplanet Proxima Centauri b will be a prime future target for characterization, despite questions about its retention of water. Climate models with static oceans suggest that an Earth-like […]

Reduced Diversity of Life Around Proxima Centauri and TRAPPIST-1
The recent discovery of habitable exoplanets around Proxima Centauri and TRAPPIST-1 has attracted much attention due to their potential for hosting life. We delineate a simple model that accurately describes […]
Cosmic Rays Near Proxima Centauri b
Cosmic rays are an important factor of space weather determining radiation conditions near the Earth and it seems to be essential to clarify radiation conditions near extrasolar planets too. Last […]
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 […]
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 […]
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 […]
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 […]
