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星表中恒星的精确参数和消光。学生将创建一个计算工具来分配恒星的温度和亮度。该工具将使模型恒星大气与GAIA的距离和其他星表的光度相匹配。由介入性尘埃引起的消光将被导出。该学生将使用该工具获得天空区域的高分辨率消光剖面，研究星际尘埃云的结构并搜索星团。
