Macroscopic Geo-Magnetic Radiation Model Polarization effects finite volume calculations
2011/1/11
An ultra-high-energy cosmic ray (UHECR) colliding with the Earth's atmosphere gives rise to an Extensive Air Shower (EAS). Due to different charge separation mechanisms within the thin shower front co...

2010/11/10
Interstellar dust grains are responsible for modifying the spectral energy distribution
(SED) of galaxies, both absorbing starlight at UV and optical wavelengths and con-verting this energy into ther...
Effect of Radiative Levitation on Calculations of Accretion Rates in White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
Elements heavier than hydrogen or helium that are present in the atmospheres of white dwarfs with effective temperatures lower than 25,000 K, are believed to be the result of accretion. By measuring t...
