Abstract

HD99458 was recently discovered to be a first object of its kind: a short-period eclipsing binary hosts a spotted, chemically peculiar A-type primary star that is a delta Scuti pulsator, and an M-dwarf secondary. These phenomena should not co-exist at the same time. Based on new photometric data we find that the previously published period of the main pulsation mode is a Nyquist alias of the true period (0.036 d, and not 0.052 d) given by the Kepler sampling.

食双星中第一颗类δ天蝎座脉动Ap星
HD99458最近被发现是第一个这样的天体:一个短周期的食双星拥有一颗有斑点的,化学上特殊的a型主星,它是一颗delta Scuti脉冲星,和一颗m矮星次级星。这些现象不应该同时存在。基于新的光度测量数据,我们发现先前公布的主脉动模式周期是开普勒采样给出的真实周期(0.036 d,而不是0.052 d)的奈奎斯特别名。
