A systematic search for rings around 168 Kepler planet candidates resulted in no detections, allowing for upper limits on the size of possible rings and constraints on models of ring formation and evolution.

Observations and models of the most massive ultracompact dwarf galaxy, M59-UCD3, suggest its black hole is ~4 x 106 M⊙ and indicate M59-UCD3 may be the tidally stripped remnant of a ~109–1010 M⊙ galaxy.

Two quasi-periodic pulsations were detected in a recent solar flare: short-period pulsations typical of solar flares, and long-period pulsations more typical of stellar flares, suggesting both periods are likely common.

New in DR14 is the first public release of data from eBOSS, the first data from the second phase of APOGEE-2, and almost twice as many data cubes from the MaNGA survey as were in the previous release.

Simulations show that coupled stellar–tidal evolution of pre-main sequence binary stars removes at least one close-in circumbinary planet in 87% of multi-planet circumbinary systems.

Estimates suggest that weak detections of water vapor, ozone, and oxygen in exoplanet atmospheres can be achieved with reflected-light observations with resolution of at least 70 and signal/noise of at least 15.
