The applicability of the viscous α-parameterization of gravitational instability in circumstellar disks
E. I. Vorobyov
(Abridged) We study numerically the applicability of the effective-viscosity approach for simulating the effect of gravitational instability (GI) in disks of young stellar objects…
Secular evolution of viscous and self-gravitating circumstellar discs
E. I. Vorobyov, Shantanu Basu
We add the effect of turbulent viscosity via the α-prescription to models of the self-consistent formation and evolution of protostellar discs. Our models are non-axisymmetric and…
Graviton, ghost and instanton condensation on horizon scale of the Universe. Dark energy as a macroscopic effect of quantum gravity
Leonid Marochnik, Daniel Usikov, Grigory Vereshkov
We show that cosmological acceleration, Dark Energy (DE) effect is a consequence of the zero rest mass, conformal non-invariance of gravitons, and 1-loop finiteness of quantum grav…
Shape and orientation of stellar velocity ellipsoids in spiral galaxies
E. I. Vorobyov, Ch. Theis
We present a numerical study of the properties of the stellar velocity distribution in stellar discs which have developed a saturated, two-armed spiral structure. We follow the gro…
