标题： Bolometric Flux Estimation for Cool Evolved Stars

摘要： 光度通量（F_BOL）的估计是利用光学和近红外干涉测量法确定恒星有效温度的重要组成部分。 仅从宽波段K波段测光数据可靠估计F_BOL是在同时性和/或宽范围测光不可用的情况下，用于详细光谱能量分布（SED）拟合的有用工具，如Dyck等人在1974年所展示的。 使用现代SED拟合方法重新校准该研究中的固有F_BOL与观测F_2.2um关系，这些方法结合了INGS光谱库（Pickles 1998库的更新版）中显著非黑体的实测光谱模板和消光估计，有助于大大提高该关系的准确性和观测实用性。 我们发现预测的F_BOL值比Dyck等人（1974）预测的相应值大约低11%，这表明了SED吸收特征对光度通量曲线的影响。 显示英文摘要

摘要： Estimation of bolometric fluxes (F_BOL) is an essential component of stellar effective temperature determination with optical and near-infrared interferometry. Reliable estimation of F_BOL simply from broad-band K-band photometry data is a useful tool in those cases were contemporaneous and/or wide-range photometry is unavailable for a detailed spectral energy distribution (SED) fit, as was demonstrated in Dyck et al. (1974). Recalibrating the intrinsic F_BOL versus observed F_2.2um relationship of that study with modern SED fitting routines, which incorporate the significantly non-blackbody, empirical spectral templates of the INGS spectral library (an update of the library in Pickles 1998) and estimation of reddening, serves to greatly improve the accuracy and observational utility of this relationship. We find that F_BOL values predicted are roughly 11% less than the corresponding values predicted in Dyck et al. (1974), indicating the effects of SED absorption features across bolometric flux curves.
