History lessons from chemical elements
Chemical elements are pretty good history teachers! Today’s paper describes how chemical abundances can tell us about the history of where a planet formed.
Magnetically Tangled: Before Ever After
Magnetic field lines of protoplanetary disks can tangle up like hair! Today’s bite presents exciting observations of such tangled field lines.
A story about a haunted protoplanetary disk…
Happy spooky season, folks! This is a story about a haunted protoplanetary disk…
Diffusion and depletion of carbon monoxide in disks
Where is the missing carbon monoxide in protoplanetary disks? Today’s paper suggests that it might have something to do with turbulent mixing in disks as well as the physics of condensation.
Fly-bye, Baby: a review of the impact of stellar flybys on protoplanetary disks
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.
Understanding the surprising narrowness of eccentric debris belts
Some extrasolar debris belts are not just eccentric but also surprisingly narrow. What processes can influence the width of debris belts?
