R. J. Filwett et al 2017 ApJ 838 23

Analysis of suprathermal heavy ion abundances in 41 corotating interaction regions (compression regions corotating with the Sun) confirm that these ions are accelerated locally, rather than by shocks beyond 1 AU.

Condensation of heavy elements keeps ice-giant planet atmospheres hot, accelerating the planets’ cooling. This could plausibly explain the difference between Uranus’ and Neptune’s brightnesses.

Modeling suggests two fast radio bursts detected within 9 arcmin of each other over 3 years apart could have been both caused by a supernova that occurred within ~10.2 years of FRB 110220.

Huidong Hu et al 2017 ApJ 840 76

Extreme ultraviolet imaging, magnetogram, white-light, and in situ observations from SDO, STEREO, SOHO, VEX, and Wind reveal the dynamics and evolution of a CME ejected from an area linking two active regions.

Samantha K. Trumbo et al 2017 AJ 153 250

Near-infrared spectroscopy of the surface of Europa revealed a previously unseen spectral feature in the trailing hemisphere consistent with that of a radiolytic product created by electron or ion bombardment.

Chao He et al 2017 ApJL 841 L31

Planetary atmosphere simulation experiments reveal that changing initial levels of CO in planetary atmospheres affects the gas phase chemistry, the density, and the composition of the solids.
