 ==== Kilonovae ====
-Kilonovae are electromagnetic transients observable in the infrared, optical, and ultraviolet bands. They originate from the neutron-rich outflows that are created during and after the merger of a binary neutron star or black hole – neutron star systems.
+Kilonovae are electromagnetic transients observable in the infrared, optical, and ultraviolet bands (see below for a comparison between the observed data for AT2017gfo and theoretical predictions).
+Kilonovae originate from the neutron-rich outflows that are created during and after the merger of a binary neutron star or black hole – neutron star systems. During these outflows, it is possible that due to the r-process (see below), heavy, unstable elements can form. These unstable elements decay and form the heavy elements that are present in our Universe. During this decay, they release energy and heat the outflowing material. At some point, the opacity of the ejected material becomes so low that photons can escape, and we are able to observe the thermal spectrum of the merger outflows.
