Programme

This is a JINA-CEE supported workshop that aims to bring together different areas of research that all involve studies of heated neutron star crusts. This includes observations of different manifestations of neutron stars, theoretical calculations and simulations, and nuclear experiments. One of the primary goals of this dedicated workshop is to have a facilitated discussion about the puzzling source of shallow crustal heating, and what observations/experiments/calculations are needed to move forward.
