恒星光谱的信息量

On the Information Content of Stellar Spectra

Jesper Schou

摘要:

随着星震观测质量的不断提高,在模式参数估计中尽量减少随机误差和系统误差是很重要的。为此,重要的是要理解振荡如何与直接观察到的量(如强度和光谱)以及导出量(如多普勒速度)相关。在这里,我列出了一些我们需要考虑的影响,并展示了其中一些影响的例子。

英文摘要:

With the increasing quality of asteroseismic observations it is important to minimize the random and systematic errors in mode parameter estimates. To this end it is important to understand how the oscillations relate to the directly observed quantities, such as intensities and spectra, and to derived quantities, such as Doppler velocity. Here I list some of the effects we need to take into account and show an example of the impact of some of them.
