Tracer trajectories from binary neutron star mergers with long-lived remnants (M1 neutrino transport)

Tracer-particle trajectories from eight numerical-relativity simulations of binary neutron star mergers that form long-lived neutron star remnants, performed with M1 neutrino transport. The simulations span two equations of state (DD2 and SFHo), different total masses and mass ratios. For each simulation, the tracers are divided into dynamical and wind ejecta. Each tracer file contains time, temperature, density, radius and electron fraction. See the README.md for the file format and details. These tracers were post-processed with the nuclear reaction network WinNet to compute the r-process nucleosynthesis yields of the MARTINI platform (https://martini.oa-abruzzo.inaf.it). The reference paper is "The MARTINI platform II. Tracing r-process nucleosynthesis in neutron star mergers with long-lived remnants", [arXiv:2610.37893](https://arxiv.org/abs/2610.37893).
