2-D Radiation Transfer Model of Non-Spherically Symmetric Dust Shell in P roto-Planetary Nebulae
We have fitted the HST images and the spectral energy distributions (SEDs) of three proto-planetary nebulae (PPN) with a 2-D

76 mas speckle-masking interferometry of IRC+10216 with the SAO 6m telescope: Evidence for a clumpy shell structure
We present the first K'-band image of the carbon star IRC+10216 with 76 mas resolution. The diffraction-limited image was reconstructed

Algorithm for generating quasiperiodic packings of icosahedral three-shell clusters
The strip projection method is the most important way to generate quasiperiodic patterns with predefined local structure. We have obtained

Algorithm for Generating Quasiperiodic Packings of Multi-Shell Clusters
Many of the mathematical models used in quasicrystal physics are based on tilings of the plane or space obtained by

Analysis of a Shell System in General Relativity
This Thesis concerns a thin fluid shell embedded in its own gravitational field. The starting point is a work of

Anomalous Scaling from Controlled Closure in a Shell Model of Turbulence
We present a model of hydrodynamic turbulence for which the program of computing the scaling exponents from first principles can

Are dust shell models well-suited to explain interferometric data of late-type stars in the near-infrared?
Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars

A reformulation of the Barrabes-Israel null-shell formalism
We consider a situation in which two metrics are joined at a null hypersurface. It often occurs that the union

Aspects of on-shell supersymmetry
We study classical field theories that do not admit an action principle, implying that their formulation is entirely in terms

ate helium flash in V605 Aql: PNe evolution and shell formation in quick motion
The "born-again" PNe V605 Aql (A58) and V4344 Sgr (Sakurai) give us the rare chance to follow shell formation and

A unified formalism for the core mass-luminosity relations of shell-burning stars
The luminosity evolution of stars with highly condensed cores surrounded by nuclear-burning shell(s) is analytically investigated with the aid of

B.R.S. renormalisation of some on-shell closed algebras of symmetry transformations : the example of supersymmetric non-linear sigma models : the N=1 case
In order to study in a regularisation free manner the renormalisability of d=2 supersymmetric non-linear $\si$ models, one has to
