Fast and Accurate Prediction of Neutron Star Structure with Deep Neural Networks
Kaushikk V N, Bhaskar Biswas, Stephan Rosswog
Solving the Tolman--Oppenheimer--Volkoff (TOV) equations, together with the tidal perturbation equations, for large numbers of equation-of-state (EOS) samples is a major computatio…
Nucleosynthesis in the fast ejecta of a neutron star merger
Lukas Schnabel, Stephan Rosswog, Friedrich-Karl Thielemann +1
Neutron star mergers are today considered a major production site for rapid neutron capture elements. While the bulk of the matter escapes at fast, but non-relativistic velocities…
Binary neutron star mergers with tabulated equations of state in SPHINCS_BSSN
Swapnil Shankar, Stephan Rosswog, Peter Diener
The dynamics and observable signatures of neutron star mergers are governed by physics under the most extreme conditions. They are particularly impacted by the high-density equatio…
Binary neutron star mergers with SPHINCS_BSSN: temperature-dependent equations of state and damping of constraint violations
Bhaskar Biswas, Stephan Rosswog, Peter Diener +1
Neutron star mergers hold the key to several grand challenges of contemporary (astro-)physics. In view of the upcoming next generation of ground-based detectors, it is crucial to k…
Simultaneously Constraining the Neutron Star Equation of State and Mass Distribution through Multimessenger Observations and Nuclear Benchmarks
Bhaskar Biswas, Stephan Rosswog
With ongoing advancements in nuclear theory and experimentation, together with a growing body of neutron star (NS) observations, a wealth of information on the equation of state (E…
PSR J0952-0607: Probing the Stiffest Equations of State and r-Mode Suppression Mechanisms
Zeyue Wu, Bhaskar Biswas, Stephan Rosswog
We analyze PSR J0952-0607, the most massive and fastest spinning neutron star observed to date, to refine constraints on the neutron star equation of state (EoS) and investigate it…
