The explosion of a Type Ia supernova (SN Ia) starts in a white dwarf as a laminar deflagration at the center of the star, and soon several hydrodynamic instabilities, in particular, the Rayleigh-Taylor instability, begin to act. A cellular stationary combustion and a turbulent combustion regime are rapidly achieved by the flame and maintained up to the end… (More)
A model of compact object coupled to inhomogeneous anisotropic dark energy is studied. It is assumed a variable dark energy that suffers a phase transition at a critical density. The anisotropic Λ−Tolman-Oppenheimer-Volkoff equations are integrated to know the structure of these objects. The anisotropy is concentrated on a thin shell where the phase… (More)
A small paper to teach yourself the incredible Smalltalk language! It's so easy, it's so fun!
This paper introduces a novel approach to the drawing of three-dimensional graphs: the geometric approach. Graphs are decomposed into building elements that can easily be drawn as a geometric shape. Those elements are linked together in order to form the final layout. The proposed algorithm, Geo3D, has been implemented in the Java language and has been used… (More)
