从谱线轮廓函数分析出发,利用局部热动平衡状态Mime—Eddington近似和灰大气模型,讨论了恒星自转多卜勒成像.||主题词##4恒星;;恒星自转;;
We use the solutions of mllne-eddington approximation and the gray atmosphere model to discuss dottler imaging of rotating stellar basing on analsing function of spectral lines broadening . It is suggested that the local profile function cna be given by:Φ(γ,M,ψ)≡k(γ)* Gs(γ) here K(γ) is voigt function ;Gs(γ) is called the local rotation profile functlon Based on this, we gain the local line depth and perform.Doppler imaging proceture of starspots and abulldallce of the element.
