Not Quite a Star, Not Quite a Planet: A Planetary-Mass Object in AB Dor
In or out? Today’s paper explores whether or not an unusual object belongs to the AB Doradus moving group—and what it means if it does.

When the stars align, you just might catch a planet, a black hole, or a binary star—but it’s hard to measure its mass! What does it take to do so?
Y dwarfs are the coolest end of the stellar classification scheme, and studying these often cloudy objects comes with plenty of challenges.
In everyday life, measuring distances is easy. In astronomy, however, accurate distance measurements are complicated by a whole host of factors. These authors are improving methods to determine the distance to small M Dwarf stars.
