论文摘要
表明热和凉爽的恒星流出之间的联系对于正确预测所谓的配对超级新星(PISN)质量间隙以下最大的黑洞(BHS)的质量至关重要。 190521据称,引力波(GW)事件举办了85个太阳能团体的“不可能”的繁重的BH。在这里,我们展示了我们对金属性Z和温度依赖性质量损失的知识如何对于我们最初约有100个太阳能群星的低Z蓝色超巨人(BSG)祖细胞的进化场景至关重要。我们使用MESA恒星进化建模实验表明,只要我们可以将这样的恒星保持在8000 K以上的恒星以上,那么低Z BSG就可以避免强风,并在核心倒塌之前保持非常大的信封质量完整。这自然会导致宇宙时间依赖于PISN间隙的最大BH函数。
The link between hot and cool stellar outflows is shown to be critical for correctly predicting the masses of the most massive black holes (BHs) below the so-called pair-instability supernova (PISN) mass gap. Gravitational Wave (GW) event 190521 allegedly hosted an "impossibly" heavy BH of 85 Solar Masses. Here we show how our increased knowledge of both metallicity Z and temperature dependent mass loss is critical for our evolutionary scenario of a low-Z blue supergiant (BSG) progenitor of an initially approx 100 Solar Masses star to work. We show using MESA stellar evolution modelling experiments that as long as we can keep such stars above 8000 K such low-Z BSGs can avoid strong winds, and keep a very large envelope mass intact before core collapse. This naturally leads to the Cosmic Time dependent maximum BH function below the PISN gap.
