We study the impact of a strong flare from the M dwarf, AD Leo, on the atmospheric chemistry of a hypothetical Earth-like planet located in the habitable zone. The simulations were performed using a 1-D photochemic ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
