Journal ArticleDOI
Optical and X-ray emission from stable millisecond magnetars formed from the merger of binary neutron stars
Brian D. Metzger,Anthony L. Piro +1 more
TL;DR: In this paper, the authors investigated the expected signature of a binary neutron star merger, including the important impact of e^± pairs injected by the millisecond magnetar into the surrounding nebula, producing a pair cascade and hard X-ray spectrum.
Journal ArticleDOI
Early spectra of the gravitational wave source GW170817: Evolution of a neutron star merger.

TL;DR: In this article, the authors reported time-series spectroscopy of SSS17a from 11.75 hours until 8.5 days after the merger, and measured the photosphere cooling from 11, 000 − 900 + 3400 to 9300 − 300 + 300 kelvin and determined a photospheric velocity of roughly 30% of the speed of light.
Journal ArticleDOI
The diversity of Type II supernova versus the similarity in their progenitors

TL;DR: In this paper, the authors acknowledge the ASASSN, La Silla Quest, and LOSS surveys for discovering new SNe that made this study possible, and the W. M. Keck Observatory is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA.
Journal ArticleDOI
Electromagnetic evidence that SSS17a is the result of a binary neutron star merger
Charles D. Kilpatrick,Ryan J. Foley,Daniel Kasen,Daniel Kasen,Ariadna Murguia-Berthier,Enrico Ramirez-Ruiz,Enrico Ramirez-Ruiz,David A. Coulter,Maria R. Drout,Anthony L. Piro,Benjamin J.

D. Simon,N. Ulloa +24 more
TL;DR: In this paper, the authors synthesize the optical to near-infrared photometry and spectroscopy of SSS17a collected by the One-Meter Two-Hemisphere collaboration, finding that SSS 17a is unlike other known transients.
Journal ArticleDOI
Time-dependent models of accretion discs formed from compact object mergers
TL;DR: In this article, the authors present time-dependent models of the remnant accretion discs created during compact object mergers, focusing on the energy available from accretion at late times and the composition of the disc and its outflows.
