Observations enabled a chance reveal of a young brown dwarf losing mass nearly spherically, which may be linked to the brief phase of deuterium fusion that these stellar objects are thought to experience.

Gamma-ray bursts in high density environments such as the disk of material around an accreting black hole are likely to be long lived, with a characteristic time evolution from high- to low-energy X-ray emission.

Polarization measurements give insight into the conditions and origins of a highly structured dark interstellar cloud; the collision of turbulent gas flows followed by fragmentation of the gas is a likely origin.

A study of population synthesis models suggests that the more massive of the two members in a black hole binary system forms second, but few constraints are placed on the spins of the two components.

A chance alignment between the Parker Solar Probe and BepiColombo spacecraft allowed researchers to study the evolution of turbulent plasma very close to the Sun, a region for which we have little data.

High-resolution spectra of 35 nearby K dwarfs have been obtained and analyzed as part of an effort that will ultimately survey thousands of K dwarfs in the solar neighborhood.
