High stellar FUV/NUV ratio and oxygen contents in the atmospheres of potentially habitable planets

Recent observations of several planet-hosting M dwarfs show that most have FUV/NUV flux ratios 1000 times greater than that of the Sun. Here we show that the atmospheric oxygen contents (O 2 and O 3 ) of potentially habitable planets in this type of UV environment could be 2-3 orders of magnitude gr...
