来自两个类似盖亚的任务的外行星和土星
Exo-Jupiters and Saturns from two Gaia-like missions
摘要：
将通过两个类似盖亚的飞行任务进行天体测量，对周期长达40年左右的数千颗行星进行探测和轨道确定，这是任何其他计划中或拟议中的飞行任务都无法获得的结果。所有光谱类型的10亿颗恒星将被调查。对具有这些周期的重行星的全面了解，远远超出任何系统的雪线，将有助于更好地了解行星的形成和演化，也是在宜居带。
英文摘要：
Detection and orbit determination for thousands of planets with periods up to about 40 years would be obtained by astrometry from two Gaia-like missions, results which cannot be obtained by any other mission, planned or proposed. A billion stars of all spectral types will be surveyed. A comprehensive knowledge about heavy planets with these periods, reaching well beyond the snow line of any system, will lead to a better understanding of the formation and evolution of planets, also in the habitable zone.
