Simulations suggest that the inner solar system planets would not be directly exposed to the blast wave of a nearby supernova, suggesting that supernova material on Earth came in the form of dust, not plasma.
Researchers attempt to discern why the plasma of solar active regions has a different composition than the surrounding solar surface, finding that the reasons are complex and likely evolve as the active region evolves.
Researchers explore the outcomes of close gravitational interactions between neutron stars and main-sequence stars in the dense inner regions of globular clusters, where such interactions are likely common.
A five-year monitoring campaign allowed researchers to study the accretion variability of a low-mass stellar companion orbiting within a disk in a situation analogous to that of an accreting protoplanet.
Models of a low-mass X-ray binary provide evidence for a new kind of explosion that must be preceded by roughly a thousand years of accretion, which means that this type of explosion is likely rare.
A new catalog of variable stars, the vast majority of which are newly discovered, presents opportunities for training machine learning algorithms and studying the structure of our galaxy.
