The star HD 166620 is experiencing a magnetic activity lull similar to the Sun’s Maunder minimum; its Lyman-alpha surface flux is about a factor of two lower than fluxes observed during solar minimum.

Examining four binary systems in which the masses of the binary members are nearly equal, researchers find that the binary components show significant differences in magnetic activity and evolutionary stage.
Using numerical simulations, researchers show the viability of a formation pathway for Deimos that involves a catastrophic fragmentation and subsequent reaccretion into a dynamically cold orbit.
In archival data from the Dark Energy Camera Legacy Survey, researchers have discovered a possible dwarf planet with an orbit that brings it as close as 45 au to the Sun and also extends out into the Oort cloud.
JWST observations of a highly inclined disk around a young brown dwarf reveal the disk to be similar to those around hotter, more massive stars; the observations also suggest ongoing inflows and outflows.
Researchers identified a physical connection between a supernova remnant and the outflows of a young star, allowing them to pinpoint the remnant’s distance at 1.41 kiloparsecs and its age at 1,600–3,300 years.
