标题： Eclipse timing variations to detect possible Trojan planets in binary systems

摘要： 本文致力于研究借助掩食时间变化（ETVs）来探测密近双星系统中特洛伊行星的有利条件。 为了确定地面望远镜和空间望远镜（如过去的CoRoT和Kepler任务以及未来的Plato、Tess和Cheops任务）检测此类变化的可能性，我们研究了具有特洛伊运动行星的双星系统的动力学。 我们通过使用完整的三体问题作为动力学模型进行了数值模拟。 通过计算次级恒星和特洛伊行星不同质量下的稳定性/ETV图，我们研究了稳定性及ETVs。 此外，我们还改变了可能存在的特洛伊行星的偏心率。 借助摆动幅度$\sigma$，我们可以表明所有稳定物体是否都在摆动轨道上移动。 我们可以得出结论，许多ETVs振幅足够大，可以探测到双星系统中的类地特洛伊行星。 作为一个应用，我们准备了一份可能候选者的名单。 显示英文摘要

摘要： This paper is devoted to study the circumstances favourable to detect Trojan planets in close binary-star-systems by the help of eclipse timing variations (ETVs). To determine the probability of the detection of such variations with ground based telescopes and space telescopes (like former missions CoRoT and Kepler and future space missions like Plato, Tess and Cheops), we investigated the dynamics of binary star systems with a planet in tadpole motion. We did numerical simulations by using the full three-body problem as dynamical model. The stability and the ETVs are investigated by computing stability/ETV maps for different masses of the secondary star and the Trojan planet. In addition we changed the eccentricity of the possible Trojan planet. By the help of the libration amplitude $\sigma$ we could show whether or not all stable objects are moving in tadpole orbits. We can conclude that many amplitudes of ETVs are large enough to detect Earth-like Trojan planets in binary star systems. As an application, we prepared a list of possible candidates.
