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.

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.

The nearby (78 pc) K-star K2-266 hosts six possible planets in a compact system — including one with an inclination that is significantly misaligned with the other five planet candidates, suggesting a different origin.
