Candidate Rotating Toroids around High-Mass (Proto)Stars

Using the OVRO, Nobeyama, and IRAM mm-arrays, we searched for “disk”outflow systems in three high-mass (proto)star forming regions: G 16.59−0.05, G 23.01−0.41, and G28.87+0.07. These were selected from a sample of NH3 cores (Codella, Testi & Cesaroni) associated with OH and H2O maser emission (Foster & Caswell) and with no or very faint continuum emission. Our imaging of molecular line (includi...

Wave Excitation in Disks around Rotating Magnetic Stars

The accretion disk around a rotating magnetic star (neutron star, white dwarf or T Tauri star) is subjected to periodic vertical magnetic forces from the star, with the forcing frequency equal to the stellar spin frequency or twice the spin frequency. This gives rise bending waves in the disk that may influence the variabilities of the system. We study the excitation, propagation and dissipatio...

Geodesics around gravitational dislocations

A technique for generating spherically symmetric dislocation solutions of a direct Poincaré gauge theory of gravity based on homogeneous functions which makes Cartan torsion to vanish is presented.Static space supported dislocation and time dependent solutions are supplied.Photons move along geodesics in analogy to geodesics described by electrons around dislocations in solid state physics.Tach...

Magnetohydrodynamics of Neutrino-cooled Accretion Tori around a Rotating Black Hole in General Relativity

We present our first numerical results of axisymmetric magnetohydrodynamic simulations for neutrino-cooled accretion tori around rotating black holes in general relativity. We consider tori of mass ∼ 0.1–0.4M⊙ around a black hole of mass M = 4M⊙ and spin a = 0– 0.9M ; such systems are candidates for the central engines of gamma-ray bursts (GRBs) formed after the collapse of massive rotating ste...
