Inhomogeneous Stellar Atmospheres

Ayres，Thomas AST 96-18505 Ayres博士继续研究太阳和恒星大气中冷气体的存在。他将利用可用于红外成像和光谱分析的新仪器来1)探索动态的、不均匀的太阳表面的时间演变，2)在晚型恒星的调查中调查4.7微米处CO波段的行为作为Tef、logg、金属丰度和色球活动的函数，以及3)用3-D几何形状对太阳的不均匀外层大气进行建模，并将结果外推到恒星。***

Ayres, Thomas AST 96-18505 Dr. Ayres continues his program of research into the presence of cold gas in the solar and stellar atmospheres. He will take advantage of new instrumentation available for imaging and spectroscopy in the IR to 1) explore the temporal evolution of the dynamic, inhomogeneous solar surface, 2) investigate the behavior of CO bands at 4.7 microns as a function of Teff, log g, metallicity, and chromospheric activity in a survey of late-type stars, and 3) model the inhomogeneous outer atmosphere of the sun with 3-D geometries and extrapolate the results to stars. ***
