Using a combination of laboratory experiments and modeling, researchers suggest that the degree of cosmic ray shielding in interstellar clouds is greater than previously thought.
An important observational feature appears to be sensitive to several factors, including stellar and active galactic nucleus feedback, which heat up the intergalactic medium.
New simulations help to inform our understanding of the late-time signals from electromagnetic counterparts of neutron star mergers detected via gravitational waves.
Researchers have developed a new model that will be useful in studies of tidal interactions between low-mass stars in close binaries and between stars and their planets.
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.
