Abstract

We review the observational evidence for the empirical upper luminosity limit in the Hertzsprung-Russell Diagram. We discuss its impact on our understanding of the evolution of the most massive stars, the importance of the high mass loss events that shape the upper limit, and the instabilities that may tigger the eruptions in stars close to their Eddington Limit.

关于赫茨普龙-罗素图上端的思考

我们回顾了赫罗图中经验光度上限的观测证据。我们讨论了它对我们对大质量恒星演化的理解的影响，形成上限的高质量损失事件的重要性，以及可能引发接近爱丁顿极限的恒星爆发的不稳定性。

期刊介绍： Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered. The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing. Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
