Evidence for bipolar jets from the optical spectra of the prototypical symbiotic star Z Andromedae
Mari Burmeister, Laurits Leedjarv
We have studied optical spectra of the symbiotic star Z And, obtained during its latest outburst started in April 2006, with the aim of finding changes in the spectrum yielding clu…
Scaling properties of invariant densities of coupled Tchebyscheff maps
Stefan Groote, Christian Beck
We study 1-dimensional coupled map lattices consisting of diffusively coupled Tchebyscheff maps of N-th order. For small coupling constants a we determine the invariant 1-point and…
The dynamics of scalar-tensor cosmology from RS two-brane model
Laur Jarv, Piret Kuusk, Margus Saal
We consider a Randall-Sundrum two-brane cosmological model in the low energy gradient expansion approximation by Kanno and Soda. It is a scalar-tensor theory with a specific coupli…
Relaxation in statistical many-agent economy models
Marco Patriarca, Anirban Chakraborti, Els Heinsalu +1
We review some statistical many-agent models of economic and social systems inspired by microscopic molecular models and discuss their stochastic interpretation. We apply these mod…
Line-of-sight velocity dispersions and a mass distribution model of the Sa galaxy NGC 4594
Elmo Tempel, Peeter Tenjes
In the present paper we develop an algorithm allowing to calculate line-of-sight velocity dispersions in an axisymmetric galaxy outside of the galactic plane. When constructing a s…
Quasiparticle states of the Hubbard model near the Fermi level
A. Sherman
The spectra of the t-U and t-t'-U Hubbard models are investigated in the one-loop approximation for different values of the electron filling. It is shown that the four-band structu…
