The discovery of two additional transiting planets around WASP-47, which is already known to host two hot Jupiters, makes this system a Rosetta stone for understanding transit timing variations.

Dynamical modeling of the structure of a faint dust band observed by the InfraRed Astronomical Satellite suggests that the band is the result of a recently-disrupted asteroid.
Luis A. Zapata et al 2015 ApJ 811 L4
ALMA observations of an eruptive outflow from the binary star system XZ Tau reveal the kinematics of the flow, as well as a very compact bipolar jet emanating from XZ Tau A.

Magnetar bursts can be modeled as the superposition of a cascade of small spikes. These spikes could potentially be formed by avalanches of reconnection or crust rupture aftershocks.

Observations from the Jansky VLA showed no signatures of intermediate black hole accretion in 337 intermediate-age and old star clusters examined.
