We may be able to study the interiors of neutron stars by monitoring the gravitational waves generated when they get ripped apart by black holes, though collisions between neutron stars are likely a better target.

Dwarf galaxies and globular clusters may be an important source of hypervelocity stars, especially those that are metal poor, low mass, and reside in the Milky Way halo.

Rebecca Lin et al 2023 ApJ 945 115

Analysis of nearly 62,000 giant pulses from the Crab Nebula pulsar suggests that the plasma emitting the pulse is moving relativistically; relativistic motion may be necessary for giant pulses in general.

Proposed observing cadences for Vera Rubin Observatory’s upcoming Legacy Survey of Space and Time won’t have negative effects on eclipsing binary science, study finds.

S. S. A. Silva et al 2023 ApJL 948 L24

Around 10 hours before an active region crops up on the Sun’s surface, changes are afoot: multiple small-scale magnetic flux regions emerge and a region of divergent flows arises.

Daichi Tsuna et al 2023 ApJ 945 104

Simulations suggest that it may be possible to detect pre-explosion outbursts of supernova progenitor stars, even as far as hundreds of days in advance of the ultimate explosion.
