Light curves are presented for 4172 classical cepheids in the Small Magellanic Cloud (SMC). These data are used to estimate the relative SMC–LMC distance and the absolute distance to the SMC.

Re-analysis of archival Spitzer IRAC surveys indicate that the frequency of 0.5–13 Jupiter-mass planets at separations of 10–1000 AU is less than 9% in the study sample.

If merging black holes like those in LIGO detection GW140915 have spin, relic magnetic fields, and surrounding disk debris, the merger environment could accelerate ultrahigh-energy cosmic rays.

Hubble observations are used to search for new very small satellites of Haumea, a dwarf planet with two known satellites. Satellites similar in size to the small moons of Pluto are ruled out.

D. Crnojević et al 2016 ApJ 823 19

A wide-field stellar map of Cen A (a close massive elliptical galaxy) reveals previously unknown streams, shells, and 13 dwarf satellite candidates, including the first tidally disrupting dwarf found around Cen A.

Planetesimals captured by disks around gas giants typically spiral rapidly into the planet. Planetesimal orbits that are initially retrograde decay faster, and high gas drag can turn them to prograde orbits.
