活动恒星的磁多普勒成像

Magnetic Doppler Imaging of Active Stars

O. Kochukhov, N. Piskunov

摘要:

我们提出了一种新的实现磁多普勒成像技术,其目的是在自洽的温度和磁映射的表面结构在冷活跃的恒星。我们的磁成像程序是独一无二的,它的能力,在所有四个斯托克斯参数模型的个人光谱特征。我们讨论了新的磁多普勒成像方法的性能和固有的局限性。特别强调的是在光学和红外区域的磁敏感线的同时建模,并结合原子和分子光谱特征的信息。这两种技术可能是第一次给我们提供一种研究恒星黑子内部磁场的工具。

英文摘要:

We present a new implementation of the magnetic Doppler imaging technique, which aims at self-consistent temperature and magnetic mapping of the surface structures in cool active stars. Our magnetic imaging procedure is unique in its capability to model individual spectral features in all four Stokes parameters. We discuss performance and intrinsic limitations of the new magnetic Doppler imaging method. A special emphasis is given to the simultaneous modelling of the magnetically sensitive lines in the optical and infrared regions and to combining information from both atomic and molecular spectral features. These two techniques may, for the first time, give us a tool to study magnetic fields in the starspot interiors.
