New maps of one of the Milky Way’s satellite galaxies show evidence for the shock thought to form due to the galaxy’s motion relative to the Milky Way’s circumgalactic medium.

Researchers discover narrow calcium emission lines in the spectrum of a Type Ia supernova for the first time, possibly associated with the winds from a surviving companion star.

Models of the spectra of Neptune-like exoplanets show that this class of planets tends to have high atmospheric metallicity and low sedimentation efficiency (i.e., the clouds tended to remain fluffy rather than compact).

Simulations of high-resolution observations of an ultra-hot Jupiter suggest that this planet’s atmosphere is variable, changing on a timescale of five of its days, and experiences the formation of storms and fronts.

An investigation into galaxies that host tidal disruption events suggests that these galaxies preferentially have lower-mass supermassive black holes and may be post-merger galaxies.

Modeling shows that auroras on planets orbiting pulsars may be detectable with current instruments; such a detection would allow us to probe the atmospheres of pulsar planets as well as study the pulsar wind in detail.
