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 […]
Proxima Centauri
Was Proxima Centauri Captured by Alpha Centauri A and B?
The nearest stellar system consists of the stars Proxima, alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets […]
Do-It-Yourself Science — Is Proxima c Hiding In This Graph?
Is Proxima c hiding in this graph? This unusual Picture of the Week showcases the latest data gathered by ESO’s exoplanet hunter, the High Accuracy Radial velocity Planet Searcher (HARPS), […]
Habitable Climate Scenarios for Proxima Centauri b With a Dynamic Ocean
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 […]
An Earth-like Atmosphere May Not Survive Proxima b's Orbit
Proxima b, an Earth-size planet right outside our solar system in the habitable zone of its star, may not be able to keep a grip on its atmosphere, leaving the […]
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 […]
The Detectability of Radio Auroral Emission from Proxima B
Magnetically active stars possess stellar winds whose interaction with planetary magnetic fields produces radio auroral emission. We examine the detectability of radio auroral emission from Proxima b, the closest known […]
Flare Activity and Photospheric Analysis of Proxima Centauri
We present the analysis of emission lines in high-resolution optical spectra of the planet-host star Proxima Centauri (Proxima) classified as a M5.5V. We carry out the detailed analysis of observed […]
First Tentative Steps to Explore the Potential Climate of Proxima B
The quest to discover whether a planet orbiting our closest neighbouring star, Proxima Centauri (4.2 light years or 25 trillion miles from Earth), has the potential to support life has […]
The Full Spectral Radiative Properties of Proxima Centauri
The discovery of Proxima b, a terrestrial temperate planet, presents the opportunity of studying a potentially habitable world in optimal conditions. A key aspect to model its habitability is to […]
