Helioseismic inference of the solar radiative opacity [PDF]

Nature Communications
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current debate on its chemical composition.

Medium-induced radiative kernel with the Improved Opacity Expansion [PDF]

Journal of High Energy Physics, 2021
We calculate the fully differential medium-induced radiative spectrum at next-to-leading order (NLO) accuracy within the Improved Opacity Expansion (IOE) framework.

Increasing wintertime cloud opacity increases surface longwave radiation at a long-term Arctic observatory [PDF]

Nature Communications
As the Arctic warms, winter clouds are known and expected to change. Yet the extent to which these cloud changes amplify or dampen warming (cloud feedback) remains uncertain.

Updated Opacity Project radiative accelerations [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
Updated data for the calculation of radiative accelerations, grad, referred to as OP 2005, have been made generally available on the Web. They differ from the earlier 1997 OP data mainly in the inclusion of contributions from inner-shell processes. The frequency resolution used for OP 2005 is shown to be satisfactory except for extreme cases of low ...

Olivine’s high radiative conductivity increases slab temperature by up to 200K [PDF]

Nature Communications
The thermal evolution of slabs governs their subduction dynamics and the transport of water into Earth’s interior. However, current slab subduction models often neglect the contribution of radiative thermal conductivity (i.e., heat transport by light ...

Radiative atomic Rosseland mean opacity tables

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 forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]

, 2003
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).

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

Atoms, 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 ...
