摘要:

大质量恒星可以通过稳定的线驱动风、喷发外流或质量转移到联星伴星上来释放物质。在单颗恒星的情况下,质量被恒星风沉积到附近的环境中。在大质量恒星爆炸后,恒星喷出物与这种拱星物质(CSM)相互作用,经常导致从冲击加热的CSM和喷出物中发射出明亮的X射线线。原始物质的损失量、喷出物的质量及其能量都会影响这种X射线发射的整体光谱特性。在这里,我们提出了一个网格的核心坍缩超新星遗迹模型来自模型的大质量恒星的零年龄主序质量的$\sim$ 10 - 30 M $_\odot$从前主序阶段与风驱动的质量损失。进化是由软件包的多级管道处理的。首先,我们使用mesa(恒星天体物理学实验模块)将前主序星演化为铁核坍缩。然后,我们使用超新星爆炸代码(snec)爆炸的台面模型,并遵循他们的第一个100天后,核心崩溃。最后,我们将sNEC输出与台面质量损失率产生的CSM耦合到宇宙射线流体动力学代码(ChN)中,以模拟核心崩溃后7000年的残余阶段。在每个阶段结束时,我们将我们的输出与文献中发现的输出进行比较,并检查残留物的体积性质及其光谱的初始祖质量以及质量损失历史的基础上的任何定性和定量差异。

英文摘要:

Massive stars can shed material via steady, line-driven winds, eruptive outflows, or mass-transfer onto a binary companion. In the case of single stars, the mass is deposited by the stellar wind into the nearby environment. After the massive star explodes, the stellar ejecta interact with this circumstellar material (CSM), often-times resulting in bright X-ray line emission from both the shock-heated CSM and ejecta. The amount of material lost by the progenitor, the mass of ejecta, and its energetics all impact the bulk spectral characteristics of this X-ray emission. Here we present a grid of core-collapse supernova remnant models derived from models for massive stars with zero age main sequence masses of $\sim$ 10 - 30 M$_\odot$ evolved from the pre-main sequence stage with wind-driven mass-loss. Evolution is handled by a multi-stage pipeline of software packages. First, we use mesa (Modules for Experiments in Stellar Astrophysics) to evolve the progenitors from pre-main sequence to iron core collapse. We then use the Supernova Explosion Code (snec) to explode the mesa models, and follow them for the first 100 days following core-collapse. Finally, we couple the snec output, along with the CSM generated from mesa mass-loss rates, into the Cosmic-Ray Hydrodynamics code (ChN) to model the remnant phase to 7000 years post core-collapse. At the end of each stage, we compare our outputs with those found in the literature, and we examine any qualitative and quantitative differences in the bulk properties of the remnants and their spectra based on the initial progenitor mass, as well as mass-loss history.
