I would like to know if the atmosphere of a world similar to Titan with more methane would still be opaque (due to the production of the organic compounds in upper atmosphere) or if it would be more transparent (less hazy), since red dwarf stars produce much less UV light, except during the flares. I don't know, but maybe only during the flares the atmosphere of such worlds would turn to be opaque and orange (the UV and X-rays produced by the flare would break methane, with a descrease in surface temperature, due to the haze blocking sunlight), and when the flare period finish, the sky turn to be bluish and transparent again slowly, increasing surface temperature. Maybe in such worlds orbiting red dwarves the flare period plays an inportant role in both development and sustaining of exotic life.
Someone have any scenario suggestion?
