This code evolves the full set of Einstein equations, but contrary to other numerical relativity codes, it evolves the matter fluid via Lagrangian particles in the framework of a high-accuracy version of smooth particle hydrodynamics (SPH). The major new elements introduced here are: (i) a new method to map the stress\u2013energy tensor (known at the particles) to the spacetime mesh, based on a local regression estimate; (ii) additional measures that ensure the robust evolution of a neutron star through its collapse to a black hole; and (iii) further refinements in how we place the SPH particles for our initial data. The latter are implemented in our code <jats:monospace>SPHINCS_ID<\/jats:monospace> which now, in addition to <jats:monospace>LORENE<\/jats:monospace>, can also couple to initial data produced by the initial data library <jats:monospace>FUKA<\/jats:monospace>. We discuss several simulations of neutron star mergers performed with <jats:monospace>SPHINCS_BSSN_v1.0<\/jats:monospace>, including irrotational cases with and without prompt collapse and a system where only one of the stars has a large spin (\u03c7 = 0.5).<\/jats:p>","DOI":"10.3389\/fams.2023.1236586","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T12:58:37Z","timestamp":1697201917000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["The Lagrangian numerical relativity code SPHINCS_BSSN_v1.0"],"prefix":"10.3389","volume":"9","author":[{"given":"Stephan","family":"Rosswog","sequence":"first","affiliation":[]},{"given":"Francesco","family":"Torsello","sequence":"additional","affiliation":[]},{"given":"Peter","family":"Diener","sequence":"additional","affiliation":[]}],"member":"1965","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"161101","DOI":"10.1103\/PhysRevLett.119.161101","article-title":"GW170817: observation of gravitational waves from a binary neutron star inspiral","volume":"119","author":"Abbott","year":"2017","journal-title":"Phys Rev Lett"},{"key":"B2","doi-asserted-by":"publisher","first-page":"L12","DOI":"10.3847\/2041-8213\/aa91c9","article-title":"Multi-messenger observations of a binary neutron star merger","volume":"848","author":"Abbott","year":"2017","journal-title":"Astrophys J Lett"},{"key":"B3","doi-asserted-by":"publisher","first-page":"L14","DOI":"10.3847\/2041-8213\/aa8f41","article-title":"An ordinary short gamma-ray burst with extraordinary implications: fermi-GBM detection of GRB 170817A","volume":"848","author":"Goldstein","year":"2017","journal-title":"Astrophys J Lett"},{"key":"B4","doi-asserted-by":"publisher","first-page":"L15","DOI":"10.3847\/2041-8213\/aa8f94","article-title":"Integral detection of the first prompt gamma-ray signal coincident with the gravitational-wave event GW170817","volume":"848","author":"Savchenko","year":"2017","journal-title":"Astrophys J Lett"},{"key":"B5","doi-asserted-by":"publisher","first-page":"64","DOI":"10.1038\/nature24291","article-title":"Optical emission from a kilonova following a gravitational-wave-detected neutron-star merger","volume":"551","author":"Arcavi","year":"2017","journal-title":"Nature"},{"key":"B6","doi-asserted-by":"publisher","first-page":"1565","DOI":"10.1126\/science.aap9580","article-title":"Swift and NuSTAR observations of GW170817: detection of a blue kilonova","volume":"358","author":"Evans","year":"2017","journal-title":"Science"},{"key":"B7","doi-asserted-by":"crossref","first-page":"L17","DOI":"10.3847\/2041-8213\/aa8fc7","article-title":"The electromagnetic counterpart of the binary neutron star merger LIGO\/Virgo GW170817.
