Simulated Population III star relics residing in the Milky Way formed from z = 22 to z = 4 and make up about 1 in every 50,000 stars, with the galactic halo hosting the largest fraction of this population.

Archaeology and astronomy combine in this study of the earliest datable account of a solar eclipse, which took place in Qūfù and includes a report of a yellowish structure that is likely the solar K-corona.

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.
