Nuclear data inputs in astrophysics processes  part I
78^{th} December 2017. First session of the general workshop (to be scheduled in 2018).
Nuclear structure inputs, nucleosynthesis and Equation of state of nuclear matter
Program
This twoday discussions anticipate and are in preparation for a longer programme that will take place in autumn 2018; see the link:
Nuclear data inputs in astrophysics processes
The aims of this session are:
i) to introduce the questions related to the nucleosynthesis and to the neutron stars, and their link with the nuclear data,
ii) to start the discussions related to the questions of the equations of state of the nuclear matter, developed within various theoretical frameworks.
On 8th, discussions are planned on: i) the rprocess in neutron star mergers, ii) link between the equation of state and the coalescence of neutron stars.
Organizers: V. Lapoux (CEASaclay, DPhN contact), V. Somà (DPhN, contact).
