Inclined water maser disks can be identified by searching for narrow masers near the systemic velocity that appear to emit from the position of the central black hole that they orbit.

Shugo Michikoshi and Eiichiro Kokubo 2017 ApJL 837 L13

Global N-body simulations of self-gravitating collisional particle rings indicate that the Centaur Chariklo must be even denser than the material of its two rings, which would generate wakes in its inner ring.

Duane F. Carbon et al 2017 ApJS 228 19

A new search approach for large spectrum data sets found 59 new extremely metal-poor stars, 11 new carbon-enhanced metal-poor stars, and 2 new cataclysmic variable stars in the SDSS DR10 data set.

F. Moreno et al 2017 ApJL 837 L3

Deep-imaging observations, orbital dynamics, and dust-tail model analyses of the double-component asteroid P/2016 J1 reveal that it likely split into two near its previous perihelion passage ~2300 days ago.

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.
