XTgrid Live:使用Tlusty模型进行在线光谱分析

XTgrid Live: Online spectral analyses with Tlusty models

Peter Nemeth

摘要:

非LTE模型大气是早期类型恒星定量光谱分析的前沿。然而,这种模型几乎没有用于大型调查,甚至用于单个系统。其主要原因可能是构建这种物理现实模型的极端计算要求。为了缓解这一问题,我们为光谱分析程序{ \sc XTgrid}开发了一个Web服务,这意味着它是{ \sc Tlusty}的一个方便界面。通过网络浏览器提供该程序,使光谱分析成为一项常规工作。

英文摘要:

Non-LTE model atmospheres are in the forefront of quantitative spectral analyses of early type stars. Yet, such models are barely used in large surveys or even for individual systems. The major reason for this is likely the extreme calculation requirements to construct such physically realistic models. To relieve this, we have developed a web-service for the spectral analysis program {\sc XTgrid}, which is meant to be a handy interface to {\sc Tlusty}. Having the procedure available from a web browser makes spectral analyses a routine.
