Magnetic Thomson Transport in High-opacity Domains

The Astrophysical Journal
X-ray radiation from neutron stars manifests itself in a variety of settings. Isolated pulsars and magnetars both exhibit quasi-thermal persistent soft X-ray emission from their surfaces.

The Spectral Temperature of Optically Thick Outflows with Application to Light Echo Spectra from $\eta$~Carinae's Giant Eruption

, 2016
The detection by Rest et al. (2012) of light echoes from $\eta$ Carinae has provided important new observational constraints on the nature of its 1840's era giant eruption.

Spatiotemporally Resolved Light Propagation in Transparent Wood

Advanced Optical Materials, EarlyView.
Light propagation mechanism changes from diffusive regime in native, white and delignified wood to near ballistic in transparent wood. Abstract Transparent wood biocomposite (TW) is a sustainable optical material that combines high transmittance with mechanical strength but also exhibits pronounced haze. This haze limits applications where high optical

Multi-Flow Falling Particle Receiver Modeling

SolarPACES Conference Proceedings
Generation 3 Concentrating Solar Power systems use solid particles for heat transfer and thermal energy storage. Particle-based systems use a falling particle receiver with an open cavity where particles flow together as a curtain that is directly ...

The stability of late-type stars close to the Eddington limit [PDF]

, 1997
Super-Eddington luminosities in hydrostatic model atmospheres manifest themselves by the presence of gas pressure inversions. Such inversions are not an artifact of the assumption of hydrostatic equilibrium but can also be present in hydrodynamical model

NLTE model calculations for the solar atmosphere with an iterative treatment of opacity distribution functions

, 2008
Modeling the variability of the solar spectral irradiance is a key factor for understanding the solar influence on the climate of the Earth. As a first step to calculating the solar spectral irradiance variations we reproduce the solar spectrum for the ...
