标题： Temperature Equilibration Behind the Shock Front: an Optical and X-ray Study of RCW 86

摘要： 我们研究RCW 86超新星遗迹中多个激波后的电子-质子温度平衡。 为了测量质子温度，我们使用了已发表的和新的光学光谱，所有光谱均来自遗迹的不同位置。 对于每个位置，我们从X射线光谱中确定电子温度，并对激波前沿与X射线光谱位置之间的温度平衡进行校正。 我们确认了之前研究的结果，即激波后的电子和质子温度对于慢速激波而言与平衡一致，而对于更快的激波则偏离。 然而，我们无法确认之前报道的电子温度与质子温度比值随1/v²变化的趋势。 显示英文摘要

摘要： We study the electron-proton temperature equilibration behind several shocks of the RCW 86 supernova remnant. To measure the proton temperature, we use published and new optical spectra, all from different locations on the remnant. For each location, we determine the electron temperature from X-ray spectra, and correct for temperature equilibration between the shock front and the location of the X-ray spectrum. We confirm the result of previous studies that the electron and proton temperatures behind shock fronts are consistent with equilibration for slow shocks and deviate for faster shocks. However, we can not confirm the previously reported trend of the electron temperature to proton temperature ratio of 1/v^2.
