Observation of a Possible Superflare on Proxima Centauri
We report the observation on UT 2017.07.01 of an unusually powerful flare detected in near-infrared continuum photometry of Proxima Centauri. During a campaign monitoring the star for possible exoplanet transits, […]

Dynamical Evolution and Stability Maps of the Proxima Centauri System
Proxima Centauri was recently discovered to host an Earth-mass planet of Proxima b, and a 215-day signal which is probably a potential planet c. In this work, we investigate the […]

Exploring the Climate of Proxima B with the Met Office Unified Model
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 […]

Characterizing The Atmosphere Of Proxima b With A Space-based Mid-infrared Nulling Interferometer
Proxima b is our nearest potentially rocky exoplanet and represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35~mas (or 0.05~AU) from its […]

The First Naked-Eye Superflare Detected from Proxima Centauri
Proxima b is a terrestrial-mass planet in the habitable-zone of Proxima Centauri. Proxima Centauri’s high stellar activity however casts doubt on the habitability of Proxima b. Sufficiently bright and frequent […]

Powerful Flare from Star Proxima Centauri Detected with ALMA
Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers discovered that a powerful stellar flare erupted from Proxima Centauri last March. This finding, published in the […]

The Answer to Planetary Habitability Is Blowing in the Stellar Wind
Is there life beyond Earth in the cosmos? Astronomers looking for signs have found that our Milky Way galaxy teems with exoplanets, some with conditions that could be right for […]

Searching For Transit of Earth–mass Exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result
Proxima~Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth–mass planet around it. With an orbital period of ∼11 days, […]

Exocomets in the Proxima Centauri System and Their Importance for Water Transport
The scenario and the efficiency of water transport by icy asteroids and comets are still amongst the most important unresolved questions about the early phases of planetary systems. The detection […]
