Radiation burnthrough measurements to infer opacity at conditions close to the solar radiative zone–convective zone boundary

open access: yesPhysics of Plasmas, 2023
Recent measurements at the Sandia National Laboratory of the x-ray transmission of iron plasma have inferred opacities much higher than predicted by theory, which casts doubt on modeling of iron x-ray radiative opacity at conditions close to the solar ...

Radiative atomic Rosseland mean opacity tables

open access: yesThe Astrophysical Journal Supplement Series, 1992
For more than two decades the astrophysics community has depended on opacity tables produced at Los Alamos. In the present work we offer new radiative Rosseland mean opacity tables calculated with the OPAL code developed independently at LLNL. We give extensive results for the recent Anders-Grevesse mixture which allow accurate interpolation in ...

Radiative cooling textiles using industry-standard particle-free nonporous micro-structured fibers [PDF]

open access: yesNanophotonics
Thermal radiation is a major dissipative pathway for heat generated by the human body and offers a significant thermoregulation mechanism over a wide range of conditions.

Pseudo-Relativistic Hartree–Fock and Fully Relativistic Dirac–Hartree–Fock Calculations of Radiative Parameters in the Fifth Spectrum of Lutetium (Lu V)

open access: yesAtoms, 2022
Using two independent theoretical methods based on the pseudo-relativistic Hartree–Fock (HFR) and the fully relativistic Multiconfigurational Dirac–Hartree–Fock (MCDHF) approaches, we computed the radiative parameters (transition probabilities and ...

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...

Contrasting opacity of bridgmanite and ferropericlase in the lowermost mantle: Implications to radiative and electrical conductivity

open access: yes, 2021
Earth's lowermost mantle displays complex geological phenomena that likely result from its heterogeneous physical interaction with the core. Geophysical models of core-mantle interaction rely on the thermal and electrical conductivities of appropriate ...

Radiative Transfer with Opacity Distribution Functions: Application to Narrowband Filters [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2021
Abstract Modeling of stellar radiative intensities in various spectral passbands plays an important role in stellar physics. At the same time, direct calculation of the high-resolution spectrum and then integration of it over the given spectral passband is computationally demanding due to the vast number of atomic and molecular lines ...

A note on the contribution of multi-photon processes to radiative opacity [PDF]

open access: yes, 2017
Recently, Bailey et al. performed iron opacity measurements on the Z machine at Sandia National Laboratory in conditions close to the ones of the base of the convective zone of the Sun.
