A Sub-Earth Mass Planet Has Been Discovered Orbiting Barnard’s Star
Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered an exoplanet orbiting Barnard’s star, the closest single star to our Sun. On this newly discovered exoplanet, […]

The Most Sensitive SETI Observations Toward Barnard’s Star With FAST
Search for extraterrestrial intelligence (SETI) has been mainly focused on nearby stars and their planets in recent years. Barnard’s star is the second closest star system to the sun and […]

Assessing The Habitability of Planets Around Old Red Dwarfs
Planets orbiting close to the most abundant and longest-lasting stars in our Milky Way may be less hospitable to life than previously thought.

Directly Imaged Exoplanets In Reflected Starlight. The Importance Of Knowing The Planet Radius
We have investigated the information content in reflected-starlight spectra of exoplanets. We specify our analysis to Barnard’s Star b candidate super-Earth, for which we assume a radius 0.6 times that […]

Breezing Through The Space Environment of Barnard's Star b
A physically realistic stellar wind model based on Alfvén wave dissipation has been used to simulate the wind from Barnard’s Star and to calculate the conditions at the location of […]

Stellar Activity Analysis of Barnard's Star
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of the star, since these phenomena […]

Prospects For Detecting The Astrometric Signature of Barnard's Star b
A low-amplitude periodic signal in the radial-velocity (RV) time-series of Barnard’s Star was recently attributed to a planetary companion with a minimum mass of ∼3.2 M⊕ at an orbital period […]

A Super-Earth Planet Candidate Orbiting at the Snow-line of Barnard's Star
At a distance of 1.8 parsecs, Barnard’s star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star […]
