In this book, renowned scientists describe the various techniques used to detect and characterize extrasolar planets, or exoplanets, with a view to unveiling the “tricks of the trade” of planet detection to a wider community. The radial velocity method, transit method, microlensing method, and direct imaging method are all clearly explained, drawing attention to their advantages and limitations and highlighting the complementary roles that they can play in improving the characterization of exoplanets’ physical and orbital properties. By probing the planetary frequency at different distances and in different conditions, these techniques are helping astrophysicists to reconstruct the scenarios of planetary formation and to give robust scientific answers to questions regarding the frequency of potentially habitable worlds. Twenty years have passed since the discovery of a Jupiter-mass companion to a main sequence star other than the Sun, heralding the birth of extrasolar planetary research; this book fully conveys the exciting progress that has been achieved during the intervening period.

这本书中，著名科学家们描述了用于探测和表征系外行星的各种技术，旨在向更广泛的研究社区揭示“系外行星探测的招数”。文中详细解释了径向速度法、凌日法、引力透镜法以及直接成像法。它们的优势和局限性被凸显出来，并且强调这些方法在改善系外行星物理特性和轨道特性方面的互补作用。通过探索不同距离和不同条件下的行星频率，这些技术正在帮助天体物理学界重建行星形成的场景，并为有关宜居世界存在频率的科学问题提供坚实的解答。自20年前发现太阳系以外一颗除太阳外的主要序列恒星周围的木星质量伴星以来已经过去了二十年，这本手册全面传达了在这期间所取得的令人兴奋的进步。
