论文摘要
我们提出了一个基本模型,用于计算超新星残留种群的光度分布。我们通过结合基本进化模型的处方,为超新星残留物构建理论HA和关节[S II] - HA光度函数,从而提供了不同年龄和震动密度的SNR的冲击速度和半径,并具有减震器激发模型,从而为不同物理参数的冲击而产生了气体的发射。我们假设平坦的年龄分布,并探索不同的前打击密度分布或不同磁参数的效果。我们发现模型HA的形状与关节[S II] -HA光度函数与通过附近星系中的SNR调查测量的形状之间的一致性非常好。
We present a basic model for the calculation of the luminosity distribution of supernova remnant populations. We construct theoretical Ha and joint [S II] - Ha luminosity functions for supernova remnants by combining prescriptions from a basic evolution model that provides the shock velocity and radius for SNRs of different age and pre-shock density, with shock excitation models that give the gas emissivity for shocks of different physical parameters. We assume a flat age distribution, and we explore the effect of different pre-shock density distributions or different magnetic parameters. We find very good agreement between the shape of the model Ha and the joint [S II] - Ha luminosity functions and those measured from SNR surveys in nearby galaxies.
