标题： Anisotropic Thermal Conduction in Supernova Remnants: Relevance to Hot Gas Filling Factors in the Magnetized ISM

摘要： 我们通过数值模拟研究了各向异性热传导在超新星遗迹演化中的重要性。 与没有热传导的模拟相比，热气泡的平均温度降低了约3倍，同时热气的平均密度也增加了类似的倍数。 因此，热传导极大地减少了在整个遗迹生命周期中产生的热气体体积。 这突显了热传导在估算银河系和原星系星际介质中高温气体填充分数和高态离子发射率的重要性。 显示英文摘要

摘要： We explore the importance of anisotropic thermal conduction in the evolution of supernova remnants via numerical simulations. The mean temperature of the bubble of hot gas is decreased by a factor of ~3 compared to simulations without thermal conduction, together with an increase in the mean density of hot gas by a similar factor. Thus, thermal conduction greatly reduces the volume of hot gas produced over the life of the remnant. This underscores the importance of thermal conduction in estimating the hot gas filling fraction and emissivities in high-stage ions in Galactic and proto-galactic ISMs.
