A search for astrospheres has turned up 10 stars with ultraviolet emission coming from a region with the shape expected for a spherically symmetric wind interacting with the interstellar medium.

If the luminosity of a tidal disruption event — when a star is ripped apart by a black hole — is proportional to the amount of material that falls onto the black hole, that suggests a roughly flat black hole mass function.

JWST continues to revolutionize every field it touches, this time giving researchers an entirely new view of the conditions within the interstellar medium of galaxies in the first billion years of the universe.

A catalog of flux-corrected and de-reddened spectra of 513 stars allows for simultaneous study of H-alpha and the 280-nanometer magnesium line, both of which indicate chromospheric activity.

Massive young star clusters identified in JWST observations of a highly lensed galaxy might be the precursors to the metal-poor globular clusters seen in the universe today.
Jae-Woo Lee 2023 ApJL 948 L16
Research continues to show that seemingly simple globular clusters are actually composed of multiple populations of stars, as is the case for Messier 92, which contains a centrally concentrated metal-poor population.
