People who get excited about aliens living on planets orbiting dwarf stars are kidding themselves. These stars are a dime a dozen and make up more than 90% of all stars, their light is more strongly affected by planetary transits, and they tend not to gobble up their innermost planets when forming. It's no wonder we find exoplanets around them all the time. But there is nobody interesting living on any of them. You can really only trust type F and G stars with life. Larger stars explode so fast their planets haven't even had time to solidify, and smaller stars have to be hugged so closely that the planet is affected by the star's fickle weather patterns.
