Small star, mighty flares: ALMA shares new view of Proxima Centauri

Summary by Phys.org

At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using visible wavelengths of light, but a new study using observations with the Atacama Large Millimeter/submillimeter Array (ALMA) array highlights this star's extreme activity in radio and millimeter wavelengths, offering exciting insights about the pa…

Revealing Proxima Centauri's Extreme Flares

In this age of exoplanet discovery, the flaring of red dwarf stars (M-dwarfs) has taken on new importance. M-dwarfs are known to host many terrestrial planets in their putative habitable zones. The problem is the flaring could make their habitable zones uninhabitable.
