A study of single-lined spectroscopic binaries, in which only one set of spectral lines is observed to move back and forth over the course of an orbit, turns up a handful of candidate white dwarfs and neutron stars.

In the brief moments before collapse, hypermassive neutron stars may be capable of emitting flares and collimated jets, which could power the precursors to short-duration gamma-ray bursts.

Researchers have determined which early-time supernova properties can be reliably determined from late-time light curve data, providing a way to guide our follow-ups of survey data.

A new catalog of 5,405 nearby early-type dwarf galaxies presents the characteristics of these objects, such as whether they contain distinct galactic nuclei and what their galactic neighbors are like.
Hsien Shang et al 2023 ApJ 944 230
Bubbles resulting from outflowing material colliding with surrounding material appear to be ubiquitous in young stars, and researchers have developed a framework to understand the kinematic signatures of these structures.
Sierra L. Grant et al 2023 ApJL 947 L6
Precise spectroscopy with JWST has enabled the detection of faint spectral lines from various molecules in the protoplanetary disk GW Lupii, facilitating the first detection of 13CO2 in a planet-forming disk.
