Magnetically supramassive and hypermassive compact stars
Koji Uryu, Shijun Yoshida, Eric Gourgoulhon +6
It is known that the mass of magnetized relativistic compact star is larger than that of non-magnetized one for the same equation of state and central density, albeit the excess of…
Equilibriums of extremely magnetized compact stars with force-free magnetotunnels
Koji Uryu, Shijun Yoshida, Eric Gourgoulhon +5
We present numerical solutions for stationary and axisymmetric equilibriums of compact stars associated with extremely strong magnetic fields. The interior of the compact stars is…
Coalescence of black hole--neutron star binaries
Koutarou Kyutoku, Masaru Shibata, Keisuke Taniguchi
We review the current status of general relativistic studies for coalescences of black hole--neutron star binaries. First, high-precision computations of black hole--neutron star b…
Reducing orbital eccentricity in initial data of black hole--neutron star binaries in the puncture framework
Koutarou Kyutoku, Kyohei Kawaguchi, Kenta Kiuchi +2
We develop a method to compute low-eccentricity initial data of black hole--neutron star binaries in the puncture framework extending previous work on other types of compact binari…
New code for equilibriums and quasiequilibrium initial data of compact objects. IV. Rotating relativistic stars with mixed poloidal and toroidal magnetic fields
Koji Uryu, Shijun Yoshida, Eric Gourgoulhon +5
A new code for computing fully general relativistic solutions of strongly magnetized rapidly rotating compact stars is developed as a part of the COCAL (Compact Object CALculator)…
Revisiting the lower bound on tidal deformability derived by AT 2017gfo
Kenta Kiuchi, Koutarou Kyutoku, Masaru Shibata +1
We revisit the lower bound on binary tidal deformability tilde{Lambda} imposed by a luminous kilonova/macronova, AT 2017gfo, by numerical-relativity simulations of models that are…
