AK Sco ubvy and Geneva differential photometry

We present an analysis of 32 high-resolution echelle spectra of the pre-main sequence spectroscopic binary AK Sco obtained during 1998 and 2000, as well as a total of 72...本研究对1998年与2000年间获取的主序前（pre-main sequence）分光双星AK天蝎座（AK Sco）的32条高分辨率阶梯光栅光谱（echelle spectra），以及总计72条……展开了分析。
