Using Modules for Experiments in Stellar Astrophysics ( MESA )+ STELLA , we show that very different physical models can adequately reproduce a specific observed Type II-Plateau supernova (SN). We consider SN2004A, SN2004et, SN2009ib, SN2017eaw, and SN2017gmr, nickel-rich ( ##IMG## [http://ej.iop.org/images/2041-8205/895/2/L45/apjlab9300ieqn1.gif] {${M}_{\mathrm{Ni}}\gt 0.03{M}_{\odot }$} ) events with bolometric lightcurves and a well-sampled decline from the plateau. These events also have constraints on the progenitor radius, via a progenitor image, or, in the case of SN2017gmr, a radius from fitting shock-cooling models. In general, many explosions spanning the parameter space of progenitors can yield excellent lightcurve and Fe-line velocity agreement, demonstrating the success of scaling laws in motivating models that match plateau properties for a given radius and highlighting the degeneracy between plateau luminosity and velocity in mode...

祖半径测量对II型高原超新星爆炸建模的价值

使用恒星天体物理学（MESA）+ STELLA中的实验模块，我们显示出非常不同的物理模型可以充分再现特定的观测II型高原超新星（SN）。我们考虑了富含镍的SN2004A，SN2004et，SN2009ib，SN2017eaw和SN2017gmr（## IMG ## [http://ej.iop.org/images/2041-8205/895/2/L45/apjlab9300ieqn1.gif] { $ {M} _ {\ mathrm {Ni}} \ gt 0.03 {M} _ {\ odot} $}）事件，并带有测光曲线，并从高原地区取样良好。这些事件还通过祖体图像或在使用SN2017gmr的情况下，通过拟合激冷模型的半径对祖体半径产生约束。一般而言，许多跨越祖细胞参数空间的爆炸会产生出色的光曲线和铁线速度一致性，
