One or more bound planets per Milky Way star from microlensing observations

A statistical analysis of microlensing data from 2002–07 reveals that stars in the Milky Way are orbited by planets as a rule, rather than an exception.

Blue large-amplitude pulsators as a new class of variable stars

A previously unidentified class of variable stars has been found in OGLE survey data, characterized by periodic brightness variations on ~30-min timescales, amplitudes of ~0.3 mag and temperatures of ~30,000 K. They are potentially evolved low-mass stars.

An eclipsing-binary distance to the Large Magellanic Cloud accurate to two per cent

Observations of eight long-period, late-type eclipsing-binary systems composed of cool, giant stars are used to determine a distance to the Large Magellanic Cloud accurate to 2.2 per cent, providing a base for a determination of the Hubble constant to an accuracy of 3 per cent.

Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm

The authors present a spectrophotometric and hydrodynamical study of supernova OGLE-2014-SN-073, which had remarkably high inferred ejecta mass and energy, potentially higher than can be explained with canonical core-collapse neutrino-driven explosions.

Microlensing mass measurement from images of rotating gravitational arcs

The authors report time-series interferometric observations of a microlensing event from the ground. The lens images rotate during the series, giving the direction of motion of the lens and a very accurate Einstein ring radius. The lens is a 1.1-solar mass object at a distance of 5–6 kpc.

A kilonova as the electromagnetic counterpart to a gravitational-wave source

Observations and modelling of an optical transient counterpart to a gravitational-wave event and γ-ray burst reveal that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a source of heavy elements.

Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way

The first stars and their immediate successors should be found today in the central regions (bulges) of galaxies; old, metal-poor stars have now been found in the Milky Way bulge, including one star with an iron abundance about 10,000 times lower than that of the Sun without noticeable carbon enhancement, making it possibly the oldest known star in the Galaxy.
