Radiative Processes in Cool Star Chromospheres

Physica Scripta, 1984
Observations made with the International Ultraviolet Explorer (IUE) satellite between 1200 A and 3000 A have shown that the spectra of giant and supergiant stars later than about K O are dominated by emission from neutral atoms and singly charged ions.

Chandra X-Ray Spectral Analysis of Cooling Flow Clusters, 2A 0335+096 and Abell 2199

, 2003
We report on a spatially resolved analysis of Chandra X-ray data on a nearby typical cooling flow cluster of galaxies 2A 0335+096, together with A 2199 for a comparison. As recently found in the cores of other clusters, the temperature around the central

Stimulated radiative laser cooling

Laser Physics, 2008
Building a refrigerator based on the conversion of heat into optical energy is an ongoing engineering challenge. Under well-defined conditions, spontaneous anti-Stokes fluorescence of a dopant material in a host matrix is capable of lowering the host temperature.

Spiralling out of control: 3D hydrodynamical modelling of the colliding winds in $\eta\thinspace$Carinae

, 2010
Three dimensional (3D) adaptive-mesh refinement (AMR) hydrodynamical simulations of the wind-wind collision between the enigmatic super-massive star \etacar and its mysterious companion star are presented which include radiative driving of the stellar ...

Magnetic Reconnection with Radiative Cooling. I. Optically-Thin Regime

, 2010
Magnetic reconnection, a fundamental plasma process associated with a rapid dissipation of magnetic energy, is believed to power many disruptive phenomena in laboratory plasma devices, the Earth magnetosphere, and the solar corona.

Winds driven by super-star clusters: The self-consistent radiative solution

, 2004
Here we present a self-consistent stationary solution for spherically symmetric winds driven by massive star clusters under the impact of radiative cooling. We demonstrate that cooling may modify drastically the distribution of temperature if the rate of

Radiative sky cooling: fundamental physics, materials, structures, and applications

Nanophotonics, 2017
Radiative sky cooling reduces the temperature of a system by promoting heat exchange with the sky; its key advantage is that no input energy is required.

Radiative cooling: arising from practice and in turn serving practice

Nanophotonics
Radiative cooling, as a renewable cooling technology, is expected to mitigate growing global warming. However, the barrier when promoting radiative cooling from the laboratory to practice is still a blind spot and needs to be discussed right now.
