Breaks in the Radial Oxygen Abundance and Corotation Radius of Three Spiral Galaxies
S. Scarano, J. R. D. Lepine, M. M. Marcon-Uchida
The correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemo-d…
An analytical approach to the dwarf galaxies cusp problem
Rafael S. de Souza, Emille E. O. Ishida
An analytical solution for the discrepancy between observed core-like profiles and predicted cusp profiles in dark matter halos is studied. We calculate the distribution function f…
Chirikov Diffusion in the Asteroidal Three-Body Resonance (5,-2,-2)
Fernando Cachucho, Pablo M. Cincotta, Sylvio Ferraz-Mello
The theory of diffusion in many-dimensional Hamiltonian system is applied to asteroidal dynamics. The general formulations developed by Chirikov is applied to the Nesvorný-Morbidel…
Are the magnetic fields of millisecond pulsars ~ 10^8 G?
Rafael S. de Souza, Reuven Opher
It is generally assumed that the magnetic fields of millisecond pulsars (MSPs) are G. We argue that this may not be true and the fields may be appreciably greater. We…
Henon-like maps with arbitrary stationary combinatorics
P. E. Hazard
We extend the renormalisation operator introduced in \cite{dCML} from period-doubling Hénon-like maps to Hénon-like maps with arbitrary stationary combinatorics. We show the renorm…
