Carl Melis and P. Dufour 2017 ApJ 834 1

Observations of this white dwarf star reveal heavy elements that indicate the WD recently accreted rocky material like that of our Moon, perhaps coming from the outer layers of a differentiated object.

Vladimir S. Airapetian et al 2017 ApJL 836 L3

Many Earth-like exoplanets around M and K stars will lose a significant fraction of their atmospheric oxygen and nitrogen due to XUV radiation, rendering them uninhabitable within a few 10–100 Myr.

Klaus Scherer et al 2016 ApJ 833 38

A careful treatment of the change in entropy across shocks is developed in this work, providing a better picture of how fluid behaves at the interface of the heliosphere (or an astrosphere) with the ISM.

Daniel Foreman-Mackey et al 2016 AJ 152 206

A fully automated search for long-period exoplanets with only 1 or 2 transits in the archival Kepler light curves of 40,000 Sun-like target stars found 16 long-period exoplanet candidates.

Ken’ichi Tatematsu et al 2017 ApJS 228 12

Observations of 13 Planck cold clumps with the James Clerk Maxwell Telescope/SCUBA-2 and the Nobeyama 45-m radio telescope allow for investigation of the starless clumps’ chemical evolutionary stages.

S. Xu (许偲艺) et al 2017 ApJL 836 L7

The discovery of the accretion of a Kuiper-Belt-Object analog onto the atmosphere of a white dwarf reveal that such objects could deliver volatiles to terrestrial planets beyond the solar system.
