Newly discovered planet AF Lep is leading its star astray
Direct imaging exoplanets is difficult, but a new method of vetting targets has just helped three independent teams discover, and image, a new gas giant.

Some extrasolar debris belts are not just eccentric but also surprisingly narrow. What processes can influence the width of debris belts?
Is there a ninth planet in the solar system? Today’s paper examines the orbital clustering of some Kuiper belt objects and where the planet causing these gravitational perturbations may be found.
We can learn a lot about colliding neutron stars from their gravitational waves, but can we also find out how circular their orbits were before they collided? Find the answer, and what it means for future binary neutron star merger detections with today’s paper.
The orbits of some hot Neptunes are not as circular as they should be
In mid August 600 astronomers met in Reykjavik, Iceland Extreme Solar Systems IV.
