355颗K2-C1天区变星校准的恒星参数
Listed in ScienceDB
Description
LAMOST是位于中国科学院国家天文台兴隆观测站的大视场多目标光谱望远镜，目前拥有世界上最大的低分辨率光谱数据库，其地理位置决定了它可观测到赤纬Dec -10度以上的天区，LAMOST为众多空间项目提供了地面支持，其中包括对K2-C1（Ra:11:35:46，Dec: 01:25:02）天区脉动变星和食双星的观测。本数据利用LAMOST第三次释放的恒星参数对K2-C1天区355颗有周期变化的脉动变星和食双星的基本恒星参数进行校准，校准后的巨星和矮星有效温度误差大约为131K和104K，表面重力加速度误差大约为0.19dex和0.16dex，金属丰度误差为0.15dex和0.10dex，此数据精度将对K2-C1天区变星的研究有推动作用。
