2017 - 2027年用XMM-牛顿观测热大质量恒星的前景

Perspectives for observing hot massive stars with XMM-Newton in the years 2017 -- 2027

Gregor Rauw

摘要:

XMM-牛顿已经深刻地改变了我们对热的大质量恒星的X射线发射的看法。高分辨率的X射线光谱学以及对这些天体的监测帮助我们更深入地了解了有或没有磁场的大质量恒星的物理学,以及两颗恒星的恒星风相互作用的大质量双星系统。这些观测还揭示了许多以前意想不到的特征,这些特征挑战了我们对大质量恒星恒星风动力学的理解。我简要总结了过去15年取得的成果,并强调了未来十年的前景。预计协调(X射线和光学或紫外线)监测和对大质量单星或双星的时间要求严格的观测将成为未来几年这一领域最重要的课题。与现有或即将推出的X射线天文台(NuSTAR,Swift,eROSITA)的协同作用也将发挥重要作用,并将进一步增强XMM-牛顿在我们寻求理解热大质量恒星物理学方面的重要性。

英文摘要:

XMM-Newton has deeply changed our picture of X-ray emission of hot, massive stars. High-resolution X-ray spectroscopy as well as monitoring of these objects helped us gain a deeper insight into the physics of single massive stars with or without magnetic fields, as well as of massive binary systems, where the stellar winds of both stars interact. These observations also revealed a number of previously unexpected features that challenge our understanding of the dynamics of the stellar winds of massive stars. I briefly summarize the results obtained over the past 15 years and highlight the perspectives for the next decade. It is anticipated that coordinated (X-ray and optical or UV) monitoring and time-critical observations of either single or binary massive stars will become the most important topics in this field over the coming years. Synergies with existing or forthcoming X-ray observatories (NuSTAR, Swift, eROSITA) will also play a major role and will further enhance the importance of XMM-Newton in our quest for understanding the physics of hot, massive stars.
