双星系统中的AM星

Am stars in binary systems

I. Iliev, J. Budaj

摘要:

有人认为,除了众所周知的依赖性的Am现象的质量,年龄(有效温度,重力)和旋转也有一个复杂的依赖性的轨道参数在二进制系统。这就是为什么需要重新审视普遍接受的假设,即Am星的旋转起着独特的作用,旋转,轨道周期和偏心率之间的强烈相关性需要得到适当的解决,并考虑到潮汐效应。本文综述了双星系统中Am星的最新观测结果。

英文摘要:

It is argued that apart from the well known dependence of the Am phenomenon on the mass, age (effective temperature, gravity) and rotation there is also a complex dependence on the orbital parameters in binary systems. This is why the generally accepted scenario in which the Am star rotation plays a unique role needs to be revisited, the strong correlations between the rotation, orbital period and eccentricity need to be properly addressed and tidal effects taken into account. Recent observations of Am stars in binary systems are reviewed.
