Balachandran, Suchitra 96-18335 Dr. Balachandran will research stellar structure and chemical evolution using infrared echelle spectroscopy on several large telescopes. Carbon and Oxygen abundances will be measured for metal-poor dwarf stars and giants to examine their variation with metallicity. Iron and alpha process abundances will be determined in globular clusters in the Galactic Bulge. Several other stellar evolution studies will be conducted, based on the comparison of observed and predicted CNO abundances and isotopic ratios in giants. ***

Balachandran，Suchitra 96-18335 Balachandran博士将在几台大型望远镜上使用红外梯形光谱研究恒星结构和化学演化。将测量贫金属矮星和巨星的碳和氧丰度，以考察它们随金属丰度的变化。铁和阿尔法过程的丰度将在银河系凸起的球状星团中确定。基于观测和预测的巨星中CNO丰度和同位素比率的比较，还将进行其他几项恒星演化研究。***
