William Janesh et al 2017 ApJL 837 L16
An optical counterpart to AGC 249525, an ultra-compact high-velocity cloud, has been discovered that has stellar properties within the observed range of gas-poor ultra-faint dwarf galaxies in the Local Group.

Radio emission is detected from tidal disruption event candidate XMMSL1 J0740−85, making it the fifth (and nearest) TDE with radio emission found. The emission likely arises from a non-relativistic outflow.

The effect of orbital inclination on the Proxima Centauri planet is calculated in terms of mass, radius, atmosphere, and albedo and discussed in the context of future photometry and imaging missions.
Erika R. Nesvold et al 2017 ApJL 837 L6
Collisional and dynamical simulations demonstrate that the observed asymmetric morphology of HD 106906’s disk is caused by perturbations from the observed exterior companion, an 11-Jupiter-mass planet.

The brightest star in the Trapezium group, θ1 Ori C, dominates ionization of the bright inner part of the Orion Nebula, but the extended component of the nebula is primarily ionized by emission from θ2 Ori A.

The “Kepler dichotomy” for exoplanetary systems may be explained by the action of an external giant planet or stellar companion misaligned with the inner multi-planet system.
