ALMA has revealed a misaligned inner gas disk inside the ~120-AU cavity in the face-on transitional disk 2MASS J16042165-2130284; its internal asymmetric structures may cause observed light-curve variations of the host star.

EPIC 246851721 b is a “tropical” Jupiter in a 6.18-day orbit around a bright, rapidly rotating F star; it has an aligned spin–orbit geometry that is likely to be primordial rather than a result of tidal damping.

The Magellanic Quasars Survey, which targeted the Large Magellanic Cloud and 70% of the Small Magellanic Cloud, identified a sample of 44 blazar candidates located behind the Clouds.
Kevin France et al 2018 ApJS 239 16
A survey of far-ultraviolet emission-line spectra from over 100 F, G, K, and M dwarfs reveals that exoplanet host stars display factors of 5–10 lower UV activity levels compared with the non-planet-hosting sample.
Kornpob Bhirombhakdi et al 2018 ApJL 868 L32
Deep X-ray limits identify a missing energy problem in SLSNe-I, a nearby hydrogen-poor superluminous supernova that has been studied in X-rays to detect the spindown powered emission from a magnetar engine.
Maria Cristina Baglio et al 2018 ApJ 867 114
During its 2017/2018 outburst, black hole X-ray binary candidate MAXI J1535–571 exhibited significant mid-infrared short-timescale variability, suggesting the presence of a flickering jet.
