Y. Fukui et al 2016 ApJ 820 26

Observations of two molecular clouds in RCW 38, the youngest super star cluster in the Milky Way, suggest they are currently colliding, triggering the formation of ~20 O stars in the cluster center.

S. A. Jaeggli and A. A. Norton 2016 ApJ 820 L11

Evaluation of the trends in complexity of active regions with solar cycle suggest that complex active regions are formed by the pileup of frequent magnetic flux emergence during solar maximum.

Duncan Christie et al 2016 ApJ 820 3

Hydrodynamic simulations of the interaction of hot-Jupiter atmospheres with stellar winds reveal that at high temperatures, supersonic planetary winds are formed. At low temperatures, these are shut off.

P. M. Saz Parkinson et al 2016 ApJ 820 8

Machine learning techniques can classify Fermi/LAT sources as AGN or pulsars with >96% accuracy, and pulsars as young or millisecond with ~90% accuracy. This can be used to identify unassociated sources.

Nicholas W. Troup et al 2016 AJ 151 85

Initial results are presented for 382 of the most compelling stellar/substellar companion candidates detected by APOGEE, found orbiting a variety of host stars in diverse environments in the Milky Way.

Vincent L. Fish et al 2016 ApJ 820 90

Initial observations by the Event Horizon Telescope demonstrate that the mm emission from the Galactic-center black hole Sagittarius A* is asymmetric on scales similar to the black hole’s shadow.
