The orbits of some recently discovered exoplanets seem to be synchronised with the rotation of their host stars. Can this mystery be explained?
Vega’s system of debris disks can be explained by a series of planets that constantly transport material inwards towards the star.
A recent result on the commonality of exoplanets has made headlines, but has it for the right reasons?
The Kepler Space Telescope gets a promising second chance with a new mission called “K2″.
Planets orbiting close to type-M dwarf stars are in the habitable zone, but if their orbits are in a 3:2 spin resonance, do their long, strange days and nights have a chance of supporting photosynthetic life?
Tune in now for the first extrasolar weather map of a nearby brown dwarf, made using Doppler imaging.
Close encounters with a passing star can excite a planet into an eccentric or inclined orbit. But a circumstellar disk can damp a planet’s eccentricity and inclination. Who wins? Find out when the authors of this paper model a stellar flyby with two circumstellar disks!
A simple and elegant (but hard) alternative method for measuring exoplanet masses.
This month’s undergraduate research post features an intriguingly-shaped disk harboring planets, and a study to unmask sneaky, previously-misclassified AGN.
For planets too old for plate tectonics, a companion planet could drive tidal heating to keep conditions primed for life.
