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.

A systematic study on 2p → 3d radiative opacity of lowly charged Cu plasmas [PDF]
AIP Advances, 2021 The L-shell radiative opacity of lowly charged Cu plasmas is investigated using a detailed level accounting method. The transmission spectra are compared with a recent experiment at ∼16 eV and 0.005 g/cm3, and good agreement is observed. For a systematic

Stellar Pulsation and Evolution: A Combined Theoretical Renewal and Updated Models (SPECTRUM). I. Updating Radiative Opacities for Pulsation Models of Classical Cepheid and RR-Lyrae [PDF]
The Astrophysical JournalPulsating stars are universally recognized as precise distance indicators and tracers of stellar populations. Their variability, combined with well-defined relationships between pulsation properties and intrinsic evolutionary parameters such as ...

QCD antenna radiative spectrum in dense media within the Improved Opacity Expansion [PDF]
Journal of High Energy PhysicsWe compute the double differential inclusive spectrum for the emission of a soft gluon from a color-singlet $$q\overline{q }$$ pair traversing a dense QCD medium. Our results extend the existing literature by simultaneously incorporating both single hard

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.

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 ...
