Dynamically Stable Magnetic Fields in Relativistic Neutron Stars: A Diverse Landscape of GRMHD Equilibria
Mai Li, Vasileios Paschalidis, Antonios Tsokaros +2
Neutron stars endowed with purely poloidal or purely toroidal magnetic fields are known to be unstable, and settle into mixed poloidal-toroidal configurations. The end state of the…
General-relativistic resistive-magnetohydrodynamics simulations of self-consistent magnetized rotating neutron stars
Patrick Chi-Kit Cheong, Antonios Tsokaros, Milton Ruiz +4
We present the first general-relativistic resistive magnetohydrodynamics simulations of self-consistent, rotating neutron stars with mixed poloidal and toroidal magnetic fields. Sp…
Evolution of equal mass binary bare quark stars in full general relativity: could a supramassive merger remnant experience prompt collapse?
Enping Zhou, Kenta Kiuchi, Masaru Shibata +2
We have evolved mergers of equal-mass binary quark stars, the total mass of which is close to the mass shedding limit of uniformly rotating configurations, in fully general relativ…
Great Impostors: Extremely Compact, Merging Binary Neutron Stars in the Mass Gap Posing as Binary Black Holes
Antonios Tsokaros, Milton Ruiz, Stuart L. Shapiro +2
Can one distinguish a binary black hole undergoing a merger from a binary neutron star if the individual compact companions have masses that fall inside the so-called mass gap of $…
Differentially rotating strange star in general relativity
Enping Zhou, Antonios Tsokaros, Koji Uryu +2
Rapidly and differentially rotating compact stars are believed to be formed in binary neutron star merger events, according to both numerical simulations and the multi-messenger ob…
Uniformly rotating, axisymmetric and triaxial quark stars in general relativity
Enping Zhou, Antonios Tsokaros, Luciano Rezzolla +2
Quasi-equilibrium models of uniformly rotating axisymmetric and triaxial quark stars are computed in general relativistic gravity scenario. The Isenberg-Wilson-Mathews (IWM) formul…
Modeling differential rotations of compact stars in equilibriums
Koji Uryu, Antonios Tsokaros, Luca Baiotti +3
Outcomes of numerical relativity simulations of massive core collapses or binary neutron star mergers with moderate masses suggest formations of rapidly and differentially rotating…
Do triaxial supramassive compact stars exist?
Koji Uryu, Antonios Tsokaros, Luca Baiotti +4
We study quasiequilibrium solutions of triaxially deformed rotating compact stars -- a generalization of Jacobi ellipsoids under relativistic gravity and compressible equations of…
Equilibrium solutions of relativistic rotating stars with mixed poloidal and toroidal magnetic fields
Koji Uryu, Eric Gourgoulhon, Charalampos Markakis +3
Stationary and axisymmetric solutions of relativistic rotating stars with strong mixed poloidal and toroidal magnetic fields are obtained numerically. Because of the mixed componen…
