Using SDSS’s Baryon Oscillation Spectroscopic Survey spectra, a library of empirical stellar spectra is created with extensive temperature (spectral types O5 – L3) and metallicity (−2.0 – +1.0 dex) coverage.

Paul D. Lasky et al 2017 ApJL 843 L1

The first measurement is made of the braking index of two putative millisecond magnetars born in short gamma-ray bursts: n = 2.9 ± 0.1 and n = 2.6 ± 0.1.

Thomas Barclay et al 2017 ApJ 841 86

Dynamical models of ejected material during late-stage planet formation suggest that ~2.5 terrestrial-mass planets are ejected per star in the Galaxy, possibly contributing to the free-floating planet population.

Several habitability conditions are fulfilled automatically by circumbinary planets of main-sequence stars, whereas on Earth, these conditions are fulfilled only by chance.

Phyllis M. Lugger et al 2017 ApJ 841 53

Chandra X-ray sources in a globular cluster are matched with optical counterparts, including 16 cataclysmic variables whose properties support production by dynamical interaction near the cluster center.

F. J. Abellán et al 2017 ApJL 842 L24

ALMA observations of SN 1987A reveal the detailed morphology of cold molecular gas in the innermost regions of the remnant, providing constraints for progenitor and explosion models.
