Gaia DR2 proper motions confirm that four young, main-sequence stars formed locally, in situ, in the Large Magellanic Cloud’s periphery, establishing that recent star formation has occurred in the outskirts of the LMC.

41 new high-redshift quasars and luminous galaxies have been spectroscopically identified at 5.7 ≤ z ≤ 6.9 by a Subaru survey, bringing the total to 137 extremely red sources identified with Subaru’s Hyper Suprime-Cam.

Hydrodynamic simulations suggest that extreme UV photoionization from a host star is the most important mechanism for launching photoevaporative winds that can erode the atmospheres of sub-Neptunes.

A catalog of interesting targets in Kepler Campaign 16, identified through photometry alone, includes 30 high-quality planet candidates, 48 more ambiguous events, and 395 regularly periodic variable sources.

Simulations show that when a helium-star-descended black hole is formed in a failed supernova explosion, the spin of the black hole is primarily determined by the initial binary separation, not the supernova energy.

Observations of the neutron-star merger GW170817 have ruled out some equations of state for dense matter, due to upper and lower limits that have been placed on average tidal deformability.
