TL;DR: It is demonstrated that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis, which is dissimilar to classical short gamma-ray bursts with ultrarelativistic jets.

TL;DR: In this paper, the authors established the physical association of an electromagnetic counterpart EM170817 to gravitational waves (GW 170817) detected from merging neutron stars by synthesizing a panchromatic dataset.

Photometric and spectroscopic evolution of the Type IIP supernova SN 2004et
TL;DR: In this article, the authors present optical photometry and spectroscopy of the normal type IIP supernova SN2004A which was discovered in the galaxy NGC 6207 on 2004 January 9.

iPTF13bvn: the first evidence of a binary progenitor for a type Ib supernova
Melina C. Bersten,Omar Gustavo Benvenuto,Omar Gustavo Benvenuto,Gastón Folatelli,Ken'ichi Nomoto,Hanindyo Kuncarayakti,Hanindyo Kuncarayakti,Shubham Srivastav,G. C. Anupama,Robert M. Quimby,D. K. Sahu +10 more
TL;DR: In this paper, an interacting binary system was proposed as the supernova progenitor and the remaining companion was a luminous O-type star of significantly lower flux in the optical than the pre-SN object.
