A survey of six gas giants orbiting F-type stars suggests that atmospheric escape of these planets is determined by the X-ray and extreme-ultraviolet output of their host stars as well as the Roche filling factor.

Using simulations of 20 asteroids from 0.05 to 2.4 au away, researchers demonstrate how the technique of topocentric parallax could be used to determine the distance to an asteroid in a single night.

Simulations suggest that Rubin Observatory will discover 1–2 meter-size or larger imminent impactors each year, nearly doubling the discovery rate and providing an important set of eyes in the Southern Hemisphere.

Researchers have found a rare example of a blue straggler star in the process of formation, providing direct evidence for the formation of these puzzling stars through ongoing mass transfer in a binary system.

In a sample of 171 new dual active galactic nuclei, four triplets, and one quadruplet drawn from a catalog of nearly a million quasars, researchers find that roughly 16% of targets exhibit tidal features.

Researchers find a system inclination of 41.8 degrees for WR 104; this result is at odds with previous interpretations of the system’s dust plume, but a new geometric model reconciles these results.
