The search for life as we know it on Earth-like, rocky exoplanets has been a driving force for many telescope missions of the new century. And, as today’s authors point out, M-Dwarfs seem more and more like great places to look.
M-Dwarfs (aka Red Dwarfs) are typically really dim, lightweight stars (relative to the Sun), which seem to account for most of the stars in the universe. Because M-Dwarfs are so small and faint, the signs that planets are orbiting them show up more clearly than for planets orbiting Sun-like stars. ...
That’s where today’s authors come in. By mapping the distributions of various stellar cycles for a survey of M-Dwarfs, the authors aim to make it easier to distinguish between signals of stellar activity and signals of orbiting planets. ...
