Times of minima for 21 early-type SMC eccentric EBs

We present the apsidal motion and light-curve analyses of 21 eccentric eclipsing binaries located in the Small Magellanic Cloud. Most of these systems have never been studied...本研究针对位于小麦哲伦星系（Small Magellanic Cloud）中的21颗偏心食双星（eclipsing binaries）开展了拱线运动（apsidal motion）与光变曲线（light-curve）分析，其中绝大多数此类系统此前从未被研究过……
