Gas pressure maxima could cause dust rings in protoplanetary disks, but fluid instabilities should quickly disrupt these maxima; new work uses this fact to constrain the properties of dust-ring-inducing gas bumps.

Calculations of the luminosity of kilonovae appear to be highly sensitive to the rates at which certain nuclear species split apart into more stable species by emitting an electron or positron.
Early observations from the Daniel K. Inouye Solar Telescope enabled the study of an umbral flash: a sudden brightening of the solar chromosphere, possibly due to shock waves, seen via its spectrum.

Using models, researchers have explored how the radiation environment and rotation rate affect the atmospheric dynamics of sub-Neptunes, a common type of planet that does not exist in our solar system.

New radio observations suggest that star formation drives molecular outflows from high-redshift, quasar-hosting galaxies with little to no contribution from the active galactic nucleus necessary.

A test of intensity interferometry — correlating the changes in a star’s intensity as seen by multiple telescopes — shows how the system can be used on telescopes of different designs.
