论文摘要
与其他类型相比,早期型恒星的生命短而稀缺。基于最大的Lamost光谱调查的最近发布的早期类型恒星目录,使用蓝边方法从紫外线到红外线的频带确定了恒星的固有颜色,其有效温度高达32,000 \。分析关系是针对\ emph {wise},2mass,\ emph {gaia},apass,sdss,pan-starrs1和\ emph {galex}频段的有效温度得出的固有颜色指数。结果通常与以前的工作一致。另外,大约估计了O型矮人和OB超级型的固有颜色。
Early-type stars are short lived and scarce in comparison with other types. Based on the recently released catalogs of early type stars from the largest LAMOST spectroscopic survey, the intrinsic colors of the stars with effective temperature up to 32,000\,K are determined for the bands from ultraviolet to infrared by using the blue-edge method. Analytic relations are derived for the intrinsic color index with the effective temperature for the \emph{WISE}, 2MASS, \emph{Gaia}, APASS, SDSS, Pan-STARRS1, and \emph{GALEX} bands. The results are generally consistent with previous works. In addition, the intrinsic colors of O-type dwarfs and OB supergiants are roughly estimated.
