Magnetohydrostatic atmospheres
We show that the atmospheric and magnetic height variations are coupled in all magnetohydrostatic (MHS) equilibria with gravity if any isolated weak evacuated flux tubes or hydrostatically connected non-force-free fields are present. In gas-dominated regimes, as in stellar photospheres, flux tubes expand with height to maintain pressure balance with the ambient giving a ‘magnetic canopy’ in the...
متن کاملUrban atmospheres
What is an urban atmosphere? How can we differentiate an 'atmosphere' from other facets of urban consciousness and experience? This essay explores some of the wider cultural, political, and philosophical connotations of atmospheres as a focal point for critical reflections on space and subjectivity. The idea of an 'affective atmosphere' as a distinctive kind of mood or shared corporeal phenomen...
متن کاملATOMIC IONIZATION AND OPACITIES IN PULSAR ATMOSPHERES Hydrogen Atmospheres
In the strong magnetic elds of typical radio pulsars atomic lines and photoionization edges lie in the soft X-ray part of the spectrum giving the dominant contribution to the opacity. Improved photoionization cross sections are presented for a hydrogen atmosphere and magnetic elds of 10 11 ? 10 13 G, exhibiting novel Beutler{Fano resonance features due to the contribution of autoionizing atomic...
متن کاملExact results in modeling planetary atmospheres–I. Gray atmospheres
An exact model is proposed for a gray, isotropically scattering planetary atmosphere in radiative equilibrium. The slab is illuminated on one side by a collimated beam and is bounded on the other side by an emitting and partially reflecting ground. We provide expressions for the incident and reflected fluxes on both boundary surfaces, as well as the temperature of the ground and the temperature...
متن کاملPulsating Stellar Atmospheres
We review the basic concepts, present state of theoretical models, and the future prospects for theory and observations of pulsating stellar atmospheres. Our emphasis is on radially pulsating cool stars, which dynamic atmospheres provide a general example for the differences with standard static model atmospheres.
