摘要:

我们提出了一个热光变曲线的分析模型,该模型由超新星喷出物和致密的星周介质之间的相互作用提供动力。这个模型的目的是模拟IIn型超新星,以确定其超新星喷出物和星周介质的性质。该模型不局限于稳态质量损失的情况,具有广泛的适用性。我们只考虑未受冲击的星周介质的光学深度不足以影响光变曲线的情况。我们推导出的光度演化的分析解决方案的基础上创建的相互作用的致密壳层的演变。我们比较了我们的模型和三个IIn型超新星(2005ip,2006jd,2010jl)的观测到的热光变曲线,表明我们的模型可以约束它们的超新星喷出物和星周介质的性质。我们的分析模型是支持从相同的初始条件下的数值光变曲线。

英文摘要:

We present an analytic model for bolometric light curves which are powered by the interaction between supernova ejecta and a dense circumstellar medium. This model is aimed at modeling Type IIn supernovae to determine the properties of their supernova ejecta and circumstellar medium. Our model is not restricted to the case of steady mass loss and can be applied broadly. We only consider the case in which the optical depth of the unshocked circumstellar medium is not high enough to affect the light curves. We derive the luminosity evolution based on an analytic solution for the evolution of a dense shell created by the interaction. We compare our model bolometric light curves to observed bolometric light curves of three Type IIn supernovae (2005ip, 2006jd, 2010jl) and show that our model can constrain their supernova ejecta and circumstellar medium properties. Our analytic model is supported by numerical light curves from the same initial conditions.
