Kilonova : an electromagnetic signal of heavy element nucleosynthesis
On August 17th 2017, the LIGO/VIRGO collaborations detected the gravitational signal GW170817 originating from a merger of two neutron stars. Shortly after an electromagnetic signal with an intrinsic brightness corresponding to thousand novas was detected by several telescopes worldwide, lasting around a week.

This kilonova signal has been predicted by theory long before and originates from the radioactive decay of freshly synthesized radioactive heavy nuclei produced by the r process. Hence, it answers one of the long lasting questions in nuclear astrophysics related to the astrophysical site of the r process. In this talk, I will summarize our current understanding of the r process, the answers provided by the recent observations and the remaining open questions.
