Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ... Radiation energy transfer in the slab is modeled by distribution of some particles carring small portions of radiation energy. ... The isotropic plasma approximation is...

... Particle Sizes in Saturns Rings . ... Credit: RSS , JPL , ESA , NASA Explanation: What size particles compose Saturn's rings? To help find out, the robot Cassini spacecraft now orbiting Saturn broadcast radio waves of three different wavelengths right through the rings to Earth earlier this month. The experiment was sensitive to ring particle sizes because ring particles much larger than a broadcast radio wavelength will reflect those radio waves away. ... NASA Official: Jay Norris. ...

... Figure 4. (a) Ecliptic plane crossings; and (b) distribution of heliocentric distances, for sets of 1:3 Saturnian MMR and non-resonant Orionid particles in 450 A.D. Both sets of particles evolved dynamically for 2 kyr but the dense clustering of resonant meteoroids contrasts with the large dispersion of non-resonant particles. ... Many previous works have shown the relevance and dynamics of Jovian mean motion resonances (MMR) in various meteoroid streams. ...

The classic solution for homogeneous sphere was suggested in 1899 by A.E.N. Love [ 330 ], in 1908 by G. Mie [ 342 ] and in 1909 by P. Debye [ 199 ]. ... Traditionally the theory of light scattering by a sphere is called the Mie theory. ... The exact solutions of the Mie problem for an optically active sphere (i.e. a sphere of optically active material [ 7 ]) and for a sphere with an optically active mantle were first obtained in 1974-5 by S. Bohren [ 158 , 159 ]. ...

... How do scientists know that the particles revealed after a proton or lead ion collision are different from each other, such as quarks and muons, and not just smaller pieces of protons or lead ions? If I were to smash two lead bullets together, they would break into smaller pieces, but they would still be lead.) ... When particle accelerators collide protons or lead ions, they do so within special sections of an instrument that can capture fine details. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...
