Twins in the Shadow: Phase Transitions in Proto-Neutron Stars
Jannik Milthaler, Jan-Erik Christian, Pia Jakobus +1
We study the impact of a first-order phase transition from hadronic to deconfined quark matter on the evolution of proto-neutron stars. To maximize the applicability of our results…
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…
Imaging the Meissner effect and local superfluid stiffness in a graphene superconductor
Ruoxi Zhang, Benjamin A. Foutty, Owen Sheekey +15
We report the observation of the Meissner effect in a rhombohedral graphene superconductor, realized via direct imaging of the static fringe magnetic field. In our few-micron sampl…
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…
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…
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…
Which first order phase transitions to quark matter are possible in neutron stars?
Jan-Erik Christian, Jürgen Schaffner-Bielich, Stephan Rosswog
We examine which first order phase transitions are consistent with today's astrophysical constraints. In particular, we explore how a well-constrained mass-radius data point would…
Thinking outside the box: Numerical Relativity with particles
S. Rosswog, P. Diener, F. Torsello
To date, essentially all simulation codes that solve the full set of Einstein's equations are performed in the framework of Eulerian hydrodynamics. The exception is our recently de…
On the point mass approximation to calculate the gravitational wave signal from white dwarf binaries
D. van den Broek, G. Nelemans, M. Dan +1
Double white dwarf binaries in the Galaxy dominate the gravitational wave sky and would be detectable for an instrument such as LISA. Most studies have calculated the expected grav…
