Time-series photometry of V391 Peg

V391 Peg (alias HS 2201+2610) is a subdwarf B (sdB) pulsating star that shows both p- and g-modes. By studying the arrival times of the p-mode maxima and minima through the O-C...V391 Peg（别名HS 2201+2610）是一颗同时存在p模式（p-mode）与g模式（g-mode）的脉动亚矮星B（subdwarf B，sdB）。本研究通过O-C（Observed minus Calculated，即观测时刻减计算时刻）方法分析p模式极大值与极小值的到达时间……
