Thermophoresis and Thermal Diffusion
Motivation: It turns out that a simple nonequilibrium environment created by a temperature gradient can be used to monitor the reaction kinetics of large proteins with small substrate molecules. This is probably caused by a change in the hydration layer of the protein which is influenced by subtle conformations changes induced by the binding substrate molecule. The underlying effect is thermoph...
متن کاملThe Thermal Evolution of Ultramagnetized Neutron Stars
Using recently calculated analytic and numerical models for the thermal structure of ultramagnetized neutron stars, we estimate the effects that ultrastrong magnetic fields B ≥ 10 G have on the thermal evolution of a neutron star. Understanding this evolution is necessary to interpret models that invoke “magnetars” to account for soft γ-ray emission from some repeating sources. Subject headings...
متن کاملDiffusion in differentially rotating stars
A linear stability analysis of rotating Boussinesq flows including shear, μ-gradients and radiation losses leads to modification of the classical Ledoux criterion for convective equilibrium. The role of shear in spreading the radial extent of the convective layers is briefly investigated, and we found that some effects may be expected in the latest nuclear evolutionary stages of massive stars, ...
متن کاملDiffusion in non-magnetic stars and COROT
New developments in the modeling of non-magnetic non-rotating A stars have had a major impact on our understanding of the formation of abundance anomalies in these stars. The great sensitivity of the pulsational properties as well as of the observable chemical composition to the internal mixing processes in chemically peculiar stars make these objects potentially important tools to investigate ...
متن کاملDiffusion and Settling in Ap/Bp Stars
Ap/Bp stars are magnetic chemically peculiar early A and late B type stars of the main sequence. They exhibit peculiar surface abundance anomalies that are thought to be the result of gravitational settling and radiative levitation. The physics of diffusion in these stars are reviewed briefly and some model predictions are discussed. While models reproduce some observations reasonably well, mor...
