As a flare star it is relatively quiet, only erupting on average less than once per day. 18. This is a flare star that has random, intermittent changes in brightness by up to a fivefold increase. 19. It is a flare star , which means it can suddenly increase in brightness for short periods of time. 20. He authored theoretical papers on flare stars ( predicted negative infrared flares ), interstellar matter, binary stars.
