ALMA may have serendipitously discovered two new members of our Solar System. Read on to discover how, and what these previously unidentified objects may be.
Y dwarfs are the coolest end of the stellar classification scheme, and studying these often cloudy objects comes with plenty of challenges.
Tune in now for the first extrasolar weather map of a nearby brown dwarf, made using Doppler imaging.
The Magellan telescope has directly imaged a planetary-mass companion at a projected distance of 650 AU from its star! Read on to find out how the authors detected and characterized this companion, and how they think it got there.
A “Super-Jupiter” recently discovered by direct imaging techniques may not be as it initially seemed. Hinkley et al. find the system to be older than expected and the Super-Jupiter to really be a brown dwarf.
The mass of a substellar companion can help determine whether it’s a planet or a brown dwarf. But how can you measure the mass of a companion that you can’t detect directly? Look at the disk!
