After CMEs travel a distance of roughly 10 solar radii, the background solar wind has negligible influence on their deflection and they propagate with roughly constant angular momentum.

Transiting planets have been found around 4 separate stars by the HATNet Survey. One of these, the hot Saturn around HAT-P-51, is a promising target for measuring the Rossiter-McLaughlin effect.

Travis S. Metcalfe et al 2015 ApJ 811 L37

Kepler observations of the binary system 16 Cyg A&B are used to demonstrate that stellar properties like age and composition can be reliably constrained with asteroseismic analysis.

Victor P. Debattista et al 2015 ApJ 812 L16

Measurement of the stellar velocities of red giant stars in the inner Milky Way suggest the presence of a thin, rapidly rotating, nuclear disk perpendicular to the galactic bar and extending to ~1 kpc.

This study announces 1.4 million active galactic nuclei (AGN) found with the Wide-field Infrared Survey Explorer, including ~1.1 million previously uncatalogued AGN.

Analysis of the Magellanic Stream suggest it can be decomposed into two filaments representing ram-pressure tails. There is also further evidence that the Magellanic Clouds collided 200-300 Myr ago.
