摘要:

大质量恒星是那些初始质量超过太阳8倍的恒星,最终导致超新星形式的灾难性爆炸。它们代表了宇宙中最大质量和最明亮的恒星组成部分,是锻造大部分化学元素的坩埚。这些快速演化的恒星驱动着星系的化学、结构和演化,主导着宇宙的生态--不仅是超新星,而且在它们的整个生命周期中--具有深远的影响。虽然大质量恒星中磁场的存在已不再是问题,但我们对大质量恒星磁场的基本统计性质的了解还很不完整。大质量恒星的磁性(MiMeS)项目代表了一个由国际知名研究人员组成的团队的综合性,多学科的战略,以解决与大质量恒星的复杂和令人困惑的磁性有关的“大问题”。本文介绍了加拿大-法国-夏威夷望远镜的MiMeS大型计划的第一批结果。

英文摘要:

Massive stars are those stars with initial masses above about 8 times that of the sun, eventually leading to catastrophic explosions in the form of supernovae. These represent the most massive and luminous stellar component of the Universe, and are the crucibles in which the lion's share of the chemical elements are forged. These rapidly-evolving stars drive the chemistry, structure and evolution of galaxies, dominating the ecology of the Universe - not only as supernovae, but also during their entire lifetimes - with far-reaching consequences. Although the existence of magnetic fields in massive stars is no longer in question, our knowledge of the basic statistical properties of massive star magnetic fields is seriously incomplete. The Magnetism in Massive Stars (MiMeS) Project represents a comprehensive, multidisciplinary strategy by an international team of recognized researchers to address the "big questions" related to the complex and puzzling magnetism of massive stars. This paper present the first results of the MiMeS Large Program at the Canada-France-Hawaii Telescope.
