The TESS exoplanet-hunting mission recently detected the rising and decaying optical afterglow of GRB 191016A, a long gamma-ray burst detected by Swift-BAT; such detections by TESS are likely to be made ~once per year.

Application of a newly developed classifier to data produced by next-generation spectroscopic surveys may allow us to identify the lowest-mass stars of primordial composition, based on their optical-to-infrared colors.

New observations of an on-disk prominence bubble around a filament barb has allowed for a 3D reconstruction of its structure, allowing for exploration of how the boundary is shaped by underlying magnetic fields.

Analysis of 4,050 wide binary star systems involving a white dwarf and usually a main-sequence star allowed for age determinations for 3,551 white dwarfs that can likely be extrapolated to their low-mass companions.

The properties of ~500 “yellowballs” have been measured in a pilot region of the galactic plane, demonstrating that ~20–30% of these sources contain high-mass star formation capable of becoming expanding H II regions.

A high-resolution geologic map is presented for the southwest peak-ring area of the Schrödinger basin, a region that would be well-suited to a robotic lunar sample return mission in the future.
