Can we infer the presence of multiple planets by monitoring how a star’s brightness changes outside of planetary transit?
How long does planetary migration take? Crockett et al. look for the answer by searching for hot Jupiters around extremely young stars.
Astronomers recently announced the discovery of a short period Earth-mass planet in the Alpha Centauri system. Could Earth-mass planets exist in the habitable zones of binary stars?
Low-mass stars are notoriously hard to model. What does the discovery of three new low-mass stars in binaries with Sun-like stars tell us about low-mass stars?
