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

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.

Ideas and Tools for Error Detection in Opacity Databases
Atoms, 2023 In this article, we propose several ideas and tools in order to check the reliability of radiative opacity and atomic physics databases. We first emphasize that it can be useful to verify that mathematical inequalities, which impose lower and upper ...

How Well do We Understand the Planck Feedback?
Journal of Advances in Modeling Earth Systems, 2023 A reference or “no‐feedback” radiative response to warming is fundamental to understanding how much global warming will occur for a given change in greenhouse gases or solar radiation incident on the Earth.

Effects of opacity temperature dependence on radiatively accelerated clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study how different opacity–temperature scalings affect the dynamical evolution of irradiated gas clouds using time-dependent radiation-hydrodynamics simulations. When clouds are optically thick, the bright side heats up and expands, accelerating the cloud via the rocket effect. Clouds that become more optically thick as they

The link between outgoing longwave radiation and the altitude at which a spaceborne lidar beam is fully attenuated [PDF]
Atmospheric Measurement Techniques, 2017 According to climate model simulations, the changing altitude of middle and high clouds is the dominant contributor to the positive global mean longwave cloud feedback.

Opacity Sampling in Radiative Acceleration Calculations [PDF]
The Astrophysical Journal, 2000 The accuracy requirements on atomic data for the calculation of stellar evolution with atomic diffusion are determined. In particular, the density of frequency grids needed for precise radiative acceleration (grad) calculations via the sampling method are presented.

The Radiative Transfer in Accretion Discs with Linear Plank Function: Role of Scattering Effect [PDF]
Iranian Journal of Astronomy and Astrophysics, 2020 Radiative transfer in a geometrically thin accretion disc with fnite optical depth is considered under the plane-parallel approximation. The Eddington factor that is defned as the ratio of the mean intensity to radiation stress tensor, is assumed be ...
