Radio emission of SN1993J. The complete picture: II. Simultaneous fit of expansion and radio light curves
摘要：
我们报告的同时模拟的膨胀和无线电光变曲线的SN 1993 J。我们已经开发了一个模拟代码，能够产生的合成膨胀和射电光变曲线的超新星考虑到膨胀冲击波，磁场，相对论电子的演变，以及有限的灵敏度的干涉阵列中使用的意见。我们的软件成功地适合所有可用的无线电数据SN 1993 J与超新星的标准发射模型扩展了一些物理考虑，作为一个进化的不透明度的喷出物材料，径向下降的辐射区域内的磁场，和不断变化的径向密度分布超过3100天爆炸后的星周介质。
英文摘要：
We report on a simultaneous modelling of the expansion and radio light curves of SN1993J. We have developed a simulation code capable of generating synthetic expansion and radio light curves of supernovae by taking into consideration the evolution of the expanding shock, magnetic fields, and relativistic electrons, as well as the finite sensitivity of the interferometric arrays used in the observations. Our software successfully fits all the available radio data of SN 1993J with an standard emission model for supernovae extended with some physical considerations, as an evolution in the opacity of the ejecta material, a radial drop of the magnetic fields inside the radiating region, and a changing radial density profile of the circumstellar medium beyond day 3100 after explosion.
