    Abstract: The Sachs-Wolfe Effect, a popular wavelength modifying hypothesis involving galaxy clusters and cosmic voids, is based on the belief that a propagating photon gains energy (is blueshifted) during its descent into a gravity well and loses energy (is redshifted) during the ascent as it escapes from the gravity well. A straightforward proof exposes th... Show More

    Abstract: The study presents the effect of density variation on the flow structure of a plasma gas in a slowly rotating and radiating hot sphere. The problem which is solved by general perturbation method shows that the plasma temperature decreases to a minimum at a radial distance of 1.4 solar radii and then increased to a maximum value at a radial distance...

  • Unusual Eccentricity and Inclination Distributions of Trans-Neptunian Objects and Trans-Neptunian Binaries

    Abstract: The eccentricity and inclination of trans-Neptunian objects (TNOs) decrease significantly as radius of perihelion increases. Also, the percentage of TNOs in almost circular orbits with low inclinations increases dramatically with perihelion distance. These unusual distributions presented here cannot be explained by observational bias or the poorly ... Show More

  • The Non-Uniform and Dynamic Orbits of Trans-Neptunian Objects

    Robert B. Brown, Scott R. Dahlke

    Abstract: Previously several authors have proposed the existence of one or more giant planets beyond Neptune to explain the non-uniform orbital elements for a dozen or fewer trans-Neptunian objects (TNOs). However, as shown here, it is not just twelve orbits that are non-randomly distributed. The distribution of the longitudes of ascending node, Ω, for all o... Show More
