The heat flux measured via a tectonic structure on the largest moon of Uranus can be explained by radiogenic heating if the region is ancient, but if it’s young, another source of heat is required.
Two- and three-dimensional simulations illuminate the ignition and spreading of flames during an X-ray burst, when gas accreted onto the surface of a neutron star explodes.
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.
