New research disfavors the possibility that the gravitational wave event GW 190425 is associated with the fast radio burst FRB 20190425A, which was recently found to have arisen from the galaxy UGC 10667.
The precise chemical compositions of colliding neutron stars can greatly affect the light curve of the collision; new research shows that many kilonovae will be excellent targets for upcoming ultraviolet telescopes.
The first major data sample from the Dark Energy Spectroscopic Instrument survey have been released, containing 466,447 Milky Way targets; 428,758 bright galaxies; 227,318 luminous red galaxies; and more.

A new model that has attained 99.45% precision has been used to identify 4,383 carbon stars, including 1,197 newly identified as such, out of 11,226,252 stars in the LAMOST sample
A young white dwarf may have recently transferred 0.15 solar mass of matter to its binary companion, creating a barium blue straggler star that was identified by its unusual chemical composition.
Newly spliced-together “Frankenspectra” spanning mid-infrared to far-ultraviolet wavelengths have been made available online and will aid in the study of dust on planetary bodies.
