摘要:

即将发射的詹姆斯·韦伯空间望远镜(JWST)与TRAPPIST-1行星系的独特特征相结合,应能使年轻的系外行星学领域进入温带地球大小的世界领域。事实上,该系统的接近度(12 pc)和它的主星的小尺寸(0.12 Rsun)和光度(0.05 Lsun)应该使它的七颗凌日行星的比较大气特征在一个雄心勃勃的JWST计划范围内。鉴于JWST的寿命有限,恒星的黄道位置将其能见度限制在每年100天,这项研究需要大量的观测时间,以及等待它的众多观测和理论挑战,它的全面成功将严重依赖于相关团队之间的协调和大型社区的支持。在这种情况下,我们在这里提出了一个社区倡议,旨在开发一个明确的顺序结构,用于JWST系统的研究,并在其准备和实施的各个方面进行协调,无论是在观测方面,(例如研究仪器的局限性、数据分析技术、天基和地基观测的互补性)和理论水平(例如模型开发和比较、检索技术、推断)。根据JWST第一阶段行星观测的结果,这一举措可能成为JWST致力于TRAPPIST-1研究的主要遗产计划的种子。

英文摘要:

The upcoming launch of the James Webb Space Telescope (JWST) combined with the unique features of the TRAPPIST-1 planetary system should enable the young field of exoplanetology to enter into the realm of temperate Earth-sized worlds. Indeed, the proximity of the system (12pc) and the small size (0.12 Rsun) and luminosity (0.05 Lsun) of its host star should make the comparative atmospheric characterization of its seven transiting planets within reach of an ambitious JWST program. Given the limited lifetime of JWST, the ecliptic location of the star that limits its visibility to 100d per year, the large number of observational time required by this study, and the numerous observational and theoretical challenges awaiting it, its full success will critically depend on a large level of coordination between the involved teams and on the support of a large community. In this context, we present here a community initiative aiming to develop a well-defined sequential structure for the study of the system with JWST and to coordinate on every aspect of its preparation and implementation, both on the observational (e.g. study of the instrumental limitations, data analysis techniques, complementary space-based and ground-based observations) and theoretical levels (e.g. model developments and comparison, retrieval techniques, inferences). Depending on the outcome of the first phase of JWST observations of the planets, this initiative could become the seed of a major JWST Legacy Program devoted to the study of TRAPPIST-1.
