Helioseismic inference of the solar radiative opacity [PDF]
Nature CommunicationsThe 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.

OP data on CD for mean opacities and radiative accelerations [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2004 All monochromatic opacity data from the Opacity Project (OP), together with all codes required for the calculation of mean opacities and radiative accelerations for any required chemical mixture, temperature and mass-density, are being put on a 700 Mb CD

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

Adaptive Algorithm for the Generation of Superconfigurations in Hot-Plasma Opacity Calculations
Plasma, 2022 In hot plasmas, such as the ones encountered in astrophysics or laser-fusion studies, the number of ionic excited states may become huge, and the relevant electron configurations cannot always be handled individually.

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

HELIOS-K: AN ULTRAFAST, OPEN-SOURCE OPACITY CALCULATOR FOR RADIATIVE TRANSFER [PDF]
The Astrophysical Journal, 2015 We present an ultrafast opacity calculator that we name HELIOS-K. It takes a line list as an input, computes the shape of each spectral line, and provides an option for grouping an enormous number of lines into a manageable number of bins. We implement a
