Stability of Toomre-Hayashi Disk
We investigate stability of Toomre-Hayashi model for a self-gravitating, rotating gas disk. The rotation velocity, vφ, and sound speed, cs, are spatially constant in the model. We show that the model is unstable against an axisymmetric perturbation irrespectively of the values of vφ and cs. When the ratio, vφ/cs, is large, the model disk is geometrically thin and unstable against an axisymmetri...
متن کاملNeutrino Cooled Accretion Disk and Its Stability
We investigate the structure and stability of hypercritical accretion flows around stellar-mass black holes, taking into account neutrino cooling, lepton conservation, and firstly a realistic equation of state in order to properly treat the dissociation of nuclei. We obtain the radial distributions of physical properties, such as density, temperature and electron fraction, for various mass accr...

We prove that every stability two unit disk graph has chromatic number at most 3 2 times its clique number.
متن کاملAnalysis of rifampin disk diffusion and stability in 7H10 agar.
Rifampin was incorporated into Middlebrook 7H10 medium either by adding an aliquot of the antibiotic into melted agar (final concentration 1.0 and 3.0 mug/ml) or by submerging a 5 or 15 mug of rifampin paper disk into 5 ml of melted agar contained in one quadrant of a Felson "X" plate. At intervals, plugs of agar were removed from the stored plates and assayed. Plates stored at 5 C for 28 days ...
متن کاملStability of the Magnetopause of Disk-accreting Rotating Stars
We discuss three modes of oscillation of accretion disks around rotating magnetized neutron stars which may explain the separations of the kilo-Hertz -periodic oscillations (QPO) seen in low mass Xray binaries. The existence of these compressible, non-barotropic magnetohydrodynamic (MHD) modes requires that there be a maximum in the angular velocity Ωφ(r) of the accreting material larger than t...
