Supernova from the Smashing Collision of a Binary Star

Authors: Yongfeng Yang
Comments: 9 Pages, 3 figures

Supernovae are generally believed to be triggered either in the core collapse of a massive star or in the increase of mass that a white dwarf star accumulates from a stellar companion (through accretion or merger), but a long-standing puzzle surrounding Type II supernovae is why the compact object remnant after the explosion gains a large velocity away from the core. Another unresolved problem of supernova is how to determine high rotating neutron stars that are ascribed to be a skillful kick from asymmetric collapse of a massive star, but the mechanism of this asymmetry is still unknown. Here we propose that due to orbital shrinkage the two stars of a binary star system may finally take place a smashing collision to form a supernova. The simulation of white dwarfs RX J0806.3+1527 in principle fits to the observed features of supernova.

The Interaction Between Massive and Massless Gravitons by the Perturbing Topological Field Theory

Authors: E. Koorambas
Comments: 8 pages with 4 figures,submitted to Commum.Theor.Phys, comments and criticisms are welcome

We test the N.Wu gauge theory of gravity with massive gravitons in the perturbing topological field theory framework. We show that the computation of the correlation function between massive and massless gravitons is reported up to 4-loop and appears to be unaffected by radiative correction. This result ensures the stability of the linking number between massive and massless gravitons with respect to the local perturbation, a result with potential wider applications in cosmology.

On the Geometric Unification of Gravity and Dark Energy

Authors: E. Koorambas
Comments: 8 pages,submitted to Cass.Quantum.Grav,comments and criticisms are welcome

In the framework of Finslerian geometry, we propose a geometric unification between traditional gauge treatments of gravity, represented by metric field, and dark energy, which arises as a corresponding gauge potential from the single SU (2) group. Furthermore, we study the perturbation of gravity waves caused by dark energy. This proposition may have far reaching applications in astrophysics and cosmology.

Invalid Intervals of X' Calculated by the Lorentz Transformations

Authors: Andrew Banks
Comments: 8 pages

Under Special Relativity (SR), as a consequence of the light postulate, a spherical light wave (SLW) propagates away from the light emission point in the frame in all directions at a constant velocity c . Further, assuming the standard configuration, since the Lorentz transformations (LT) are required to preserve the truth of all aspects of the SLW, then on any time interval, LT must preserve the propagation the SLW away from the origin of the primed frame. In short, since there is only one SLW under SR assuming one light pulse and given some time interval for the unprimed frame, since the set of vectors for that time interval demonstrates the propagation of the SLW away from the unprimed origin at c , then the corresponding set of LT mapped vectors must also demonstrate the SLW propagates away from the primed origin at c . More specifically, SLW expansion in one frame must translate using LT to SLW expansion for any other frame. However, it will be shown, using some arbitrary ...
