Protoplanetary disks don’t exist in isolation; when young stars pass each other by, their gravitational encounter can disrupt, or maybe even kickstart, planet formation.
Some extrasolar debris belts are not just eccentric but also surprisingly narrow. What processes can influence the width of debris belts?
When moons and rings orbit together, the results can be crazy. This paper proposes three regimes to more easily understand these complex interactions.
Interesting things are happening around the beloved Beta Pic. Bands of unexpected gas may be due to cometary collisions – but are these potential comets similar to our own?
Astronomers using ALMA have just discovered that our closest neighbor has at least one dust ring, analog to the Kuiper belt in the solar system. Sorry, but a reference to Lord of the Rings is unavoidable.
