Collapse of magnetized hypermassive neutron stars in general relativity: Disk evolution and outflows
Branson C. Stephens, Yuk Tung Liu, Stuart L. Shapiro
We study the evolution in axisymmetry of accretion disks formed self-consistently through collapse of magnetized hypermassive neutron stars to black holes. Such stars can arise fol…
Magnetized Hypermassive Neutron Star Collapse: a candidate central engine for short-hard GRBs
Branson C. Stephens, Matthew D. Duez, Yuk Tung Liu +2
Hypermassive neutron stars (HMNSs) are equilibrium configurations supported against collapse by rapid differential rotation and likely form as transient remnants of binary neutron…
Evolution of magnetized, differentially rotating neutron stars: Simulations in full general relativity
Matthew D. Duez, Yuk Tung Liu, Stuart L. Shapiro +2
We study the effects of magnetic fields on the evolution of differentially rotating neutron stars, which can form in stellar core collapse or binary neutron star coalescence. Magne…
Magnetized hypermassive neutron star collapse: a central engine for short gamma-ray bursts
Masaru Shibata, Matthew D. Duez, Yuk Tung Liu +2
A hypermassive neutron star (HMNS) is a possible transient formed after the merger of a neutron star binary. In the latest magnetohydrodynamic simulations in full general relativit…
Collapse of magnetized hypermassive neutron stars in general relativity
Matthew D. Duez, Yuk Tung Liu, Stuart L. Shapiro +2
Hypermassive neutron stars (HMNSs) -- equilibrium configurations supported against collapse by rapid differential rotation -- are possible transient remnants of binary neutron star…
Excitation Of MHD Modes With Gravitational Waves: A Testbed For Numerical Codes
Matthew D. Duez, Yuk Tung Liu, Stuart L. Shapiro +1
We consider a gravitational wave oscillating in an initially homogeneous, magnetized fluid. The fluid is perfectly conducting and isentropic, and the magnetic field is initially un…
