摘要:

与围绕单星运行的行星相比,围绕双星系统运行的行星相对未被充分探索。环双星行星及其行星系统的探测为我们理解环双星行星的形成和动力学演化提供了首个详细视角。BEBOP(Binaries Escorted by Orbiting Planets,由环绕行星伴随的双星)径向速度巡天在这一探索中扮演着特殊角色,因为它专注于食单线双星,其主星为FGK矮星、伴星为M矮星,从而能够利用HARPS和SOPHIE光谱仪实现最高的径向速度精度。我们为BEBOP巡天中的179个目标获取了4512条高分辨率光谱,并利用这些光谱通过等效宽度和光谱合成两种方法推导了恒星大气参数。此外,我们还推导了所有目标的质量、半径和年龄。通过这项工作,我们首次给出了这些食单线双星的精确恒星参数的均匀星表。

英文摘要:

Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed view into our understanding of circumbinary planet formation and dynamical evolution. The BEBOP (Binaries Escorted by Orbiting Planets) radial velocity survey plays a special role in this adventure as it focuses on eclipsing single-lined binaries with an FGK dwarf primary and M dwarf secondary allowing for the highest-radial velocity precision using the HARPS and SOPHIE spectrographs. We obtained 4512 high-resolution spectra for the 179 targets in the BEBOP survey which we used to derive the stellar atmospheric parameters using both equivalent widths and spectral synthesis. We furthermore derive stellar masses, radii, and ages for all targets. With this work, we present the first homogeneous catalogue of precise stellar parameters for these eclipsing single-lined binaries.
