Pressure Calculation of a Constant Density Star in the Dynamic Theory of Gravity

Authors: Ioannis Iraklis Haranas
Comments: 12 pages. Published Romanian Astronomical Journal, Vol. 15, No. 2, pp. 95-105, 2005

In a new theory called Dynamic Theory of Gravity, the gravitational potential is is derived from gauge relations and has a different form than the classical Newtonian potential. In the same theory an analytical expression for the pressure is derived from the equation of the hydronamic equilibrium which is solved for a star of constant density and the results are compared with those of Newtonian gravity. Changes then in the central pressure and radius are also calculated and finally a redshift calculation is performed so that the dynamic gravity effects if any might be shown to be of some detectabe magnitude.

Derivation of Weinberg's Relation in a Inflationary Universe

Authors: Ioannis Iraklis Haranas
Comments: 7 pages. Published Romanian Astronomical Journal, Vo. 13 No. 2, pp.111-117

We propose a derivation of the empirical Weinberg relation for the mass of an elementary particle and in an inflationary type of universe. Our derivation produces the standard well known Weinberg relation for the mass of an elementary particle, along with an extra term which depends on the inflationary potential, as well as Hubble's constant. The derivation is based on Zeldovich's result for the cosmological constant Λ, in the context of quantum field theory. The extra term can be understood as a small correction to the mass of the elementary particle due to inflation. This term also enables us to calculate, the initial value of the field φO for two kinds of potentials chosen, which makes Weinberg's relation possible. Closed and flat and open universes give the mass of the particles close to the mass of a pion, 140 MeV/c2 or as the one also predicted by Weinberg's relation.

Variable Model of the Fine-Structure Constant

Authors: Ioannis Iraklis Haranas
Comments: 8 pages, Romanian Astronomical Journal, Vol. 13, No. 1 pp. 25-30, 2003

Recent evidence suggests that the fine-structure constant α=e2/h bar*c, a measure of the strength of the electromagnetic interaction between photons and electrons, is slowly increasing over cosmological timescales. High-resolution measurements of quasar spectra suggest that there has been a variation Δα/α =-0.72 ± 0.18x10-5 over the past 6-10 Gyr.To model this, we propose variability in the speed of light that produces a cosmological time |αdot/α| = 10-15 and 10-16 yr-1 at z = 3 which also agrees with the observational spectral data.

Are Flyby Anomalies and the Pioneer Effect an ASTG Phenomenon?

Authors: Golden Gadzirayi Nyambuya
Comments: 5 pages, 2 figures, 2 tables, Submitted as a letter to MNRAS (MN-10-0299-L.)

This reading expounds with expediency on the recently proposed Azimuthally Symmetric Theory of Gravitation (ASTG) set-up earlier. There-in, the ASTG was set up and it was demonstrated that it is capable (amongst others solar anomalies) of explaining the precession of the perihelion of solar planets. In the second reading, it was shown that this theory is capable - in principle; of explaining outflows as a repulsive gravitational phenomenon. In the present, we show that the ASTG is capable of explaining the puzzling observations of flyby anomalies vis, anomalous asymptotic speed increases at the perigee and the speed changes occurring to the osculating hyperbolic speed excess. It is shown that these flyby anomalies are a natural occurrence in the ASTG. We derive a modified formula of the empirical formula proposed by Anderson et al., which up to now has no foundational basis except that experience suggest it. It is seen that the ASTG can in principle explain the Pioneer Anomaly. To say for sure the ASTG is the reason for the Pioneer Anomaly, there is need to obtain the complete set of the Pioneer ephemerides.

The Mass of the Universe and Other Relations in the Idea of a Possible Cosmic Quantum Mechanics

Authors: Ioannis Iraklis Haranas, Michael Harney
Comments: 2 pages, Published: Progress in Physics, vol. 3, pp. 3-8 , 2008.

General Relativity predicts the existence of relativistic corrections to the static Newtonian potential which can be calculated and verified experimentally. The idea leading to quantum corrections at large distances is that of the interactions of massless particles which only involve their coupling energies at low energies. In this short paper we attempt to propose the Sagnac intrerferometric technique as a way of detecting the relativistic correction suggested for the Newtonian potential, and thus obtaining an estimate for phase difference using a satellite orbiting at an altitude of 250 km above the surface.

An Auxiliary Gravitational Field Operating in Galaxies

Authors: R. Wayte
Comments: 22 pages, Submitted to PMC Physics A

A theory has been developed of an auxiliary relativistic gravitational field, which operates in conjunction with General Relativity gravity and accounts for the empirical success of Milgrom's modified Newtonian dynamics theory. Remarkable links between this astronomical theory and atomic physics have been discovered. Resonant, standing-wave properties of the field encourage the formation of flat rotation curves, bar or spiral structures and quantised galactic rings. Gravitational lensing due to this field is also significant. The angular momentum proportional to mass-squared relationship observed in galaxies is attributed to this field selecting a preferred galactic rotation velocity.

Evidence for Quantisation in Planetary Ring Systems

Authors: R. Wayte
Comments: 23 pages, Submitted to PMC Physics A

Absolute radial positions of the main features in Saturn's ring system have been calculated by adapting the quantum theory of atomic spectra. Fine rings superimposed upon broad rings are found to be covered by a harmonic series of the form N α A(r)1/2, where N and A are integers. Fourier analysis of the ring system shows that the spectral amplitude fits a response profile which is characteristic of a resonant system. Rings of Jupiter, Uranus and Neptune also obey the same rules. Involvement of the atomic fine structure constant throughout implies the existence of a real quantisation force linking gravitation and atomic theories.

Do Ultra High Energy Cosmic Rays Form a Part of Dark Matter?

Authors: S. Halayka
Comments: 2 Pages.

It is considered whether or not recent ultra high energy cosmic ray observations hint at the possibility that the unaccounted for higher energy rays have become dark matter.
