I tried to find a way to reply to that thread. My argument was that even if brown dwarfs were 2700k (and my book says that's closer to the temperature of red dwarfs and that brown dwarfs are usually around 1000K). Seeing that we are studying the life cycle and evolution of all stars, wouldn't either of those temperatures be on the relatively COOL side of all star temperatures? Wouldn't the most appropriate answer be D.?arrow_forward5arrow_forward
