A 10-solar-mass B-type star is the first of its spectral type known to have an accretion disk exhibiting Keplerian rotation traced by carbon monoxide lines.

Using a combination of theory and observations from multiple sources, researchers have narrowly constrained the equation of state of the center of a neutron star directly from the data.

In lab experiments, tiny cylinders made from meteorite dust remained intact longer under hotter temperatures, suggesting that dust in protoplanetary disks gets stickier at warmer locations in the disk.
More than 80 signals originating from the mergers of compact objects like neutron stars and black holes can be found in the catalog of gravitational-wave events seen by multiple detectors.
A survey of 30 supernovae for which spectra were acquired less than two days after the explosion suggests that short-lived, narrow emission lines are common, occurring in more than a third of cases.
The warm, Saturn-size planet TOI-199 b is the first of its class for which we have precise mass and radius measurements, thanks to the Antarctica Search for Transiting ExoPlanets.
