SUMMARY:Matter Outflows in Neutron Star Mergers\, Network in Neutrinos
 \, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\, Francois Fou
 cart \, University of New Hampshire
DESCRIPTION:Determining the properties of the mildly relativistic outf
 lows produced during and after the merger of neutron star binaries is 
 crucial to understand the role of mergers in the production of heavy e
 lements\, as well as to analyze multi-messenger observations of these 
 systems. The mass and composition of these outflows determine how much
  matter is available for r-process nucleosynthesis\, as well as the re
 lative abundance of the various elements produced by the r-process. Ad
 ditionally\, the properties of these matter outflows are tightly linke
 d to the observable characteristics of kilonovae. In this talk\, I wil
 l discuss what merger simulations have taught us so far about neutron 
 star merger outflows\, focusing particularly on the dynamics of black 
 hole-neutron star mergers\, and on the main sources of uncertainty in 
 current outflow models for both black hole-neutron star and neutron st
 ar-neutron star binary mergers.
