摘要:

紧三元系统的恒星呈等级结构,第三颗恒星绕着内部的双星运行,周期小于1000天。这样的系统对于理解多个系统中恒星的形成和演化非常重要。有一个分离的食双星(DEB)作为其组成部分之一,使我们能够获得这些系统的精确的恒星和轨道参数。我们讨论的过程中,以获得准确的参数,这些系统使用高分辨率光谱,径向速度测量,精确的天基测光。这使我们能够有一个三维几何图片,以及金属丰度,年龄和这些系统的进化状态。

英文摘要:

Tight Triple Systems have stars in a hierarchical configuration with a third star orbiting the inner binary with a period of fewer than 1000 days. Such systems are important for understanding the formation and evolution of stars in multiple systems. Having a detached eclipsing binary (DEB) as one of its components allows us to obtain precise stellar and orbital parameters of these systems. We discuss the process to obtain accurate parameters of these systems using high-resolution spectroscopy, radial velocity measurements, and precise space-based photometry. This enables us to have a 3D geometrical picture as well as the metallicity, age, and evolutionary status of these systems.
