Emission lines in the spectrum of a pre-main-sequence star suggest that crystalline forsterite grains formed in a 2008 outburst have migrated outward into the disk, where they might be swept up into planets.

Twenty-eight companions to stars observed with the Kepler spacecraft were studied in detail, allowing for the inflated radii of these brown dwarfs and M dwarfs to be determined.

Deep observations of the galaxy cluster Abell 98 reveal a variety of structures including a gas sloshing spiral, an X-ray tail, and cold front edges; some of these structures are indicative of ram-pressure stripping.
S. Estrada-Dorado et al 2023 ApJL 944 L46
New observations suggesting the accretion of planetary debris onto a white dwarf allow for a reassessment of previous data that were complicated by the presence of a bright source nearby.

Radiation pressure from an active galactic nucleus might be the cause for the recent burst of star formation in the central ring of the galaxy NGC 3182, which hosts young stars and metal-rich gas.

Detection of the neutral gas torus around Jupiter’s moon Europa remains difficult, with Hubble Space Telescope observations from 2020 to 2021 finding no trace of the neutral gas assumed to be present.
