We present a detailed study of M1-67, a well-known nebula around the population I Wolf-Rayet star WR 124 (WNh 8), based on datacubes obtained with the imaging Fourier transform spectrometer SITELLE at the Canada-France-Hawaii Telescope (CFHT). This allowed us to reconstruct detailed emission-line ratio maps that highlight clear orthogonal features from a chemical abundance point of view, a complete extinction map, as well as the electron density and temperature structures. In addition to this information, velocity maps were obtained shedding light on the bow shock structure due to the high velocity of WR124, qualified as a runaway star, which is about +190 km s−1 relative to the local ISM. Interaction between the latter structure and spherical and non-spherical outburst could explain the global morphology of M1-67.

SITELLE 对 WR 星云 M1-67 的新见解

我们根据加拿大-法国-夏威夷望远镜的成像傅里叶变换光谱仪 SITELLE 获得的数据立方体，对 M1-67 进行了详细研究，这是一个围绕 I Wolf-Rayet 星 WR 124 (WNh 8) 的著名星云。 CFHT）。这使我们能够重建详细的发射线比率图，从化学丰度的角度、完整的消光图以及电子密度和温度结构，突出显示清晰的正交特征。除了这些信息之外，由于 WR124 的高速度，获得了速度图，从而揭示了弓形激波结构，它是一颗失控的恒星，相对于当地的 ISM 大约是 +190 公里 s-1。后者结构与球形和非球形爆发之间的相互作用可以解释 M1-67 的整体形态。
