Understanding Massive Star Evolution and Explosion Mechanism of Supernovae

我们已经开发了一个多维辐射传输程序的超新星爆炸，包括偏振，并模拟各种多维离子分布的超新星喷出物的偏振光谱。我们还用斯巴鲁望远镜对超新星进行了偏振光谱观测。将我们的新数据添加到现有数据集，我们已经构建了Ibc型超新星的最大数据样本。通过比较模拟和观测的结果，我们发现，一个三维的几何形状是常见的超新星。

We have developed a multi-dimensional radiative transfer code for supernova explosions including polarization, and simulated polarization spectra with various multi-dimensional ion distributions in supernova ejecta. We also performed spectropolarimetric observations of supernovae with Subaru telescope. Adding our new data to the existing datasets, we have constructed the largest data samples of Type Ibc supernovae. By comparing the results of simulations and observations, we showed that a three-dimensional geometry is common in supernovae.
