In a dense globular cluster, grazing tidal encounters between subgiant stars and black holes could result in the formation of a low-mass X-ray binary with a non-degenerate donor.

The first catalog of TeV gamma-ray sources is presented from the newly completed High Altitude Water Cherenkov Observatory (HAWC) — the most sensitive TeV survey to date for such a large fraction of the sky.
T. L. Esplin et al 2017 AJ 154 46
Optical and infrared images from Spitzer Space Telescope, Hubble Space Telescope, and ground-based facilities have revealed 6 new planetary-mass brown dwarf candidates in the Chamaeleon I star-forming region.
Eli Galanti and Yohai Kaspi 2017 ApJL 843 L25
Gravity harmonics measured during the Cassini Grand Finale may be used to get an estimate of the structure of how Saturn’s gas flows and to better constrain the planet’s density structure and composition.

The Subhalo and PARticle Trajectory Analysis (SPARTA) parallel computer code can analyze the orbits of billions of particles in large cosmological simulations of dark matter halos, reliably measuring halo properties.
Krishnendu Mandal et al 2017 ApJ 842 89
New computational advancements have been made in time–distance helioseismology, a process that allows us to infer internal properties of the Sun from surface measurements of wave travel times.
