Star system features
g Two stars were separated by about 434 AUs in 1942
g Illustration of stars’ thermal structures
g Sudden flare burst can heat Star B’s outer atmosphere to around 270,000° F; this rapid heating to the presence of an intense, but unstable, magnetic field; subsequently, an x-ray flare emanates from the star

Known planets
g A: NA
g B: NA

Habitable zone
g A: An Earth-type planet would be comfortable with liquid water at an orbital distance of less than 0.084 AU (without accounting for infrared heating), with a "year" of less than 14 days.
g B: An Earth-type planet would be comfortable with liquid water at an orbital distance of 0.0017 AUs (without accounting for infrared heating), and a planetary orbit around the star would be completed in a matter of hours.
