Dissipative N-body simulations demonstrate that the GJ876 system, an M-dwarf hosting three planets orbiting in a chaotic 4:2:1 Laplace resonance, can be formed through smooth disk migration models.

ALMA’s resolved images of carbon monoxide toward the binary flows associated with the BHR 71 protostellar system reveal for the first time solid evidence that their flows are partially colliding.
Howard Chen et al 2018 ApJL 868 L6
Simulations show that changes in illumination geometry and rotation-induced circulation can influence the global distribution of atmospheric biosignatures on tidally locked exoplanets.
Pei Zuo et al 2018 ApJ 867 13
The discovery of a rare, isolated dark cloud currently undergoing H2 formation lets us examine the atomic-to-molecular transition and suggests that a classical star formation picture is favored over fast star formation models.

Estimates suggest TESS will find 1,250 ± 70 exoplanets, including 250 smaller than 2 R⊕. An additional 3,100 planets will be found in full-frame image data orbiting bright dwarf stars and more than 10,000 around fainter stars.

New photometric observations of the disintegrating planet K2-22b suggest that its transit depths are similar in 2016-2017 to what they were in 2014-2015, though there’s ongoing variability in transit shape and time.
