The X-ray data for two gamma-ray bursts are fit with a millisecond-magnetar model and a fireball-shock model; the millisecond-magnetar model is favored for most nuclear equations of state.

More than 4 million observations from the Dark Energy Survey were searched for small solar system bodies — recovering a total of 202 trans-Neptunian objects and Centaurs — and stellar occultations predicted.

John H. Debes et al 2019 ApJL 872 L25

A recent citizen-scientist discovery suggests that large-scale tidal disruption events can still occur around white dwarfs 3 billion years after the white dwarf’s formation — much later than was previously thought.

ALMA observations revealed NaCl, KCl, and their ³⁷Cl and ⁴¹K isotopologues in the high-mass protostellar disk around Orion SrcI, tracing the region just above the continuum disk and possibly forming the base of the outflow.

The unWISE Catalog, which contains the positions and fluxes of ~2 billion objects observed by WISE over the full sky, improves on the AllWISE catalog with deeper imaging and improved modeling of crowded regions.

P. Kharb et al 2019 ApJ 871 249

VLBI observations of the Seyfert type 2 galaxy KISSR 434 reveal a long (~500 light-years) jet that is curved, possibly due to precession rather than ram-pressure bending from a rotating interstellar medium.
