The inward gas flow in protoplanetary disks can cause dust to tumble into a planet-induced gap, potentially significantly impacting pebble drift and planet formation in the inner disk.

The magnetic complexity of a solar active region appears to influence the solar wind magnetic field strength, charge state, helium abundance, and other factors; complex active regions excel at generating solar wind.

Using the Hubble Space Telescope, researchers have closely examined tidal disruption event host galaxies, finding that minor mergers may enhance tidal disruption event rates in post-starburst galaxies.

Modeling suggests that drag due to solar flux acting on isolated particles is able to explain the distribution of ringed and ringless worlds in our solar system, even in the absence of additional factors.

An asterisk-shaped feature at the center of a crater on Jupiter’s moon Europa may have similar origins to “lake stars” on Earth; lab experiments show that these patterns can form in Europan ice simulant.

Using the CHARA array, researchers did not detect the hot Jupiter exoplanet Upsilon Andromedae b, despite probing planet-to-star contrast values lower than what is predicted for this planetary system.
