Differential BVRI photometry of FI Boo

We present a detailed analysis of the interesting W UMa binary FI Boo in view of the spectroscopic signature of a third body through photometry, period variation, and a thorough...本研究针对颇具研究价值的大熊座W型（W UMa）密近双星牧夫座FI（FI Boo）展开详细分析，基于第三体的光谱特征，通过测光、周期变化以及全面的研究开展相关剖析
