Abstract:

 

Neutron star mergers had long been suspected to produce gravitational waves,

gamma ray bursts and -by some- to produce heavy "rapid neutron capture" or

"r-process" elements. While overall convincing, all these conjectures were only

based on indirect arguments and none was proven by direct observations.

This changed on August 17, 2017: a gravitational wave signal from a merging

neutron star binary was detected, closely followed by a short burst of gamma-rays

and week-long transients across the electromagnetic spectrum coming from the

radioactive decay of freshly synthesised r-process elements.

In this talk I will give an overview over neutron star mergers, their roles as

precious laboratories for (astro-)physics and I will focus in particular on their role

for the production of heavy elements.
