Electromagnetic counterparts of compact object mergers powered by the radioactive decay of r‐process nuclei
The most promising astrophysical sources of kHz gravitational waves (GWs) are the inspiral and merger of binary neutron star(NS)/black hole systems. Maximizing the scientific return of a GW detectionExpand
Supernova Light Curves Powered by Young Magnetars
We show that energy deposited into an expanding supernova remnant by a highly magnetic (B ~ 5 × 1014 G) neutron star spinning at an initial period of Pi ≈ 2-20 ms can substantially brighten the lightExpand
Origin of the heavy elements in binary neutron-star mergers from a gravitational-wave event
TLDR
The ejected mass and a merger rate inferred from GW170817 imply that such mergers are a dominant mode of r-process production in the Universe. Expand
Swope Supernova Survey 2017a (SSS17a), the optical counterpart to a gravitational wave source
TLDR
A rapid astronomical search located the optical counterpart of the neutron star merger GW170817 and shows how these observations can be explained by an explosion known as a kilonova, which produces large quantities of heavy elements in nuclear reactions. Expand
Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
TLDR
Early observations of type Ia supernova SN 2011fe in the galaxy M101 at a distance from Earth of 6.4 megaparsecs find that the exploding star was probably a carbon–oxygen white dwarf, and from the lack of an early shock it is concluded that the companion was likely a main-sequence star. Expand
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/Virgo GW170817. II. UV, Optical, and Near-infrared Light Curves and Comparison to Kilonova Models

SEEING THE COLLISION OF A SUPERNOVA WITH ITS COMPANION STAR
The progenitors of Type Ia and some core collapse supernovae are thought to be stars in binary systems, but little direct observational evidence exists to confirm the hypothesis. We show that theExpand
Opacities and Spectra of the $r$-process Ejecta from Neutron Star Mergers
Material ejected during (or immediately following) the merger of two neutron stars may assemble into heavy elements through the r-process. The subsequent radioactive decay of the nuclei can powerExpand
EFFECT OF A HIGH OPACITY ON THE LIGHT CURVES OF RADIOACTIVELY POWERED TRANSIENTS FROM COMPACT OBJECT MERGERS
The coalescence of compact objects is a promising astrophysical source of detectable gravitational wave signals. The ejection of r-process material from such mergers may lead to a radioactivelyExpand
Type II Supernovae: Model Light Curves and Standard Candle Relationships
A survey of Type II supernovae explosion models has been carried out to determine how their light curves and spectra vary with their mass, metallicity, and explosion energy. The presupernova modelsExpand
