A new two-dimensional hydrodynamics code, SPLASH, has been developed to model the early stages of constant-rate accretion onto a spherical neutron star, during which a convective instability is triggered.

The presence of hydrated salts in the rocky surface material on a body like Ceres is thought to slow the retreat of the ice table; Ceres’s average equatorial temperatures show delays of a few to tens of millions of years.

The neural network model ParkerNet demonstrated strong performance in identifying and characterizing switchbacks even with only 12% of data labeled as such, providing a way to detect future switchbacks.

Repeating and non-repeating fast radio bursts appear to originate from different progenitors, environments, or emission mechanisms — but intriguingly, both appear to be consistent with a magnetar origin.

A newly discovered brown dwarf companion to an M-dwarf star is estimated to have a mass just shy of 60 Jupiter masses; the object is accessible to many investigative methods and is likely to be a useful benchmark.

Early observations of interstellar interloper 3I/ATLAS revealed a compact coma, minimal light-curve variation, and a similar visible-light/near-infrared spectral slope to other interstellar objects.
