The project will obtain accurate stellar parameters and extinction for stars in the GAIA DR3 catalogue. The student will create a computational tool to assign a temperature and luminosity to the stars. The tool will fit model stellar atmospheres to the GAIA distance and photometry from other catalogues. The extinction due to intervening dust will be derived. The student will use this tool to obtain high resolution extinction profiles across areas of the sky, to investigate the structure of the interstellar dust clouds and to search for stellar clusters.

该项目将获得 GAIA DR3 表中恒星的准确恒星参数和消光情况。学生将创建一个计算工具来为恒星分配温度和光度。该工具将把恒星大气模型与其他目录中的 GAIA 距离和光度测量相匹配。由于尘埃的介入而导致的消光将由此产生。学生将使用该工具获取整个天空区域的高分辨率消光剖面，研究星际尘埃云的结构并寻找恒星团。
