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目录中恒星的准确恒星参数和灭绝。学生将创建一个计算工具，将温度和光度分配给星星。该工具将使模型恒星大气与其他目录的距离距离和光度法拟合。由于中间的灰尘而导致的灭绝将得出。学生将使用此工具来获得跨天空区域的高分辨率灭绝曲线，以研究星际尘埃云的结构并搜索恒星簇。
