Numerical simulations of collisional disruption of rotating gravitational aggregates:Dependence on material properties
Asteroids Planetesimals Dynamics N-body simulations Collisional physics
<
2015/12/25
Our knowledge of the strengths of small bodies in the Solar System is limited by our poor understanding of their internal structures, and this, in turn, clouds our understanding of the formation and e...
Asteroids:equilibrium shapes of rotating gravitational aggregates
Asteroids shapes–Numerical simulations–Solar System evolution
<
2015/12/25
Many evidences lead us to think that a significant portion of asteroids are aggregates of boulders kept together by gravity, with little or no contribution from cohesive forces. The standard hydrodyna...
Unusual States of Vortex Matter in Mixtures of Bose-Einstein Condensates on Rotating Optical Lattices
Superfluid parameter space vortex lattice parameters the mixture of condensed matter optical lattice
<
2014/12/19
In a single-component superfluid under rotation a broken symmetry in the order parameter space results in a broken translational symmetry in real space: a vortex lattice. If translational symmetry is ...
Approximate L-State Solution of the Rotating Trigonometric P鰏chl-Teller Potential

2012/4/19
We describe a pulsed rotating supersonic beam source, evolved from an ancestral device [M. Gupta and D. Herschbach, J. Phys. Chem. A 105, 1626 (2001)]. The beam emerges from a nozzle near the tip of a...

2012/2/23
We study high energy charged particle collisions near the horizon in an electromagnetic field around a rotating black hole and reveal the condition of the fine-tuning to obtain arbitrarily large cente...
Joint downscale fluxes of energy and potential enstrophy in rotating stratified Boussinesq flows

2011/10/14
We employ a coarse-graining approach to analyze nonlinear cascades in Boussinesq flows using high-resolution simulation data. We derive budgets which resolve the evolution of energy and potential enst...
Explaining radio emission of magnetars via rotating and oscillating magnetospheres of neutron stars
MHD: pulsars — general — relativity — oscillations — magnetar — stars:neutron — death line — plasma magnetosphere
<
2011/10/10
We investigate the conditions for radio emission in rotating and oscillating magnetars, by focusing on the main physical processes determining the position of their death-lines in the P-\dot{P} diagra...
Rapidly Rotating Lenses: Repeating features in the lightcurves of short period binary microlenses
gravitational lensing: micro – celestial mechanics – binaries: general –planetary systems – Galaxy: bulge
<
2011/9/29
Microlensing is most sensitive to binary lenses with relatively large orbital separations, and as such, typical binary microlensing events show little or no orbital motion during the event. However, d...
