通过SPar方法获得的SMSS DR2中的恒星参数、消光和距离
Mingxu Sun
我们利用SPar算法为来自SkyMapper Southern Survey（SMSS）的1.41亿颗恒星提供了恒星参数，包括有效温度（Teff）、金属丰度（FeH）、绝对星等（M_{G}）、距离（d）和消光值（E_{G_{BP},G_{RP}}）。该算法采用拟合过程，通过匹配多波段的恒星测光数据，以个别恒星为基础推导出恒星参数（Teff、FeH、M_G、d和E_{G_{BP},G_{RP}}）。通过将研究范围扩展到高和低银纬的恒星，本研究成功地纠正了位于低银纬的恒星的消光效应，从而精确确定了它们的恒星参数。
