Molecular dynamics computations explore how tightly bound certain minerals are to the surfaces of planetary bodies; crystal orientation and other factors affect this value, complicating the investigation.

Simulations show that vortices are capable of creating rings and gaps like those made by planets; however, vortices are significantly more effective at opening gaps than planets are.

Misaligned dusty disks around young binary stars can precess and eventually end up in a polar orbit; future radio arrays may be capable of detecting the centimeter-sized dust grains involved in the resulting “traffic jams.”

A purported hot Jupiter gets rebranded as a low-density precursor to a sub-Neptune that may lose its atmospheric envelope entirely within a billion years.

Exploring both ends of the pulsar spectrum, researchers have discovered a millisecond pulsar and two long-period pulsars, including the slowest-spinning pulsar discovered so far.

Nearly all — 99.6% — of the 72,964 unobscured quasar candidates in a new catalog of the southern sky have never been previously identified as such via spectroscopy.
