论文摘要
可居住的系外行星天文台（HABEX）被设计为2030年代的伟大天文台。在人类历史上，技术已经足够成熟，以实现负担得起的空间望远镜任务，能够发现和表征与附近明亮的阳光恒星绕着绕着明亮的阳光般旋转的地球般的行星，以便寻找可居住性和生物签名的迹象。这样的任务还可以配备仪器，从而使当前或计划中的设施不可能实现广泛而令人兴奋的一般天体物理学和行星科学。 HABEX是一个空间望远镜，具有独特的成像和多对象光谱功能，其波长范围从紫外线（UV）到近IR。这些功能允许一系列引人入胜的科学套件，这些科学削减了整个NASA天体物理学作品集。 Habex有三个主要的科学目标：（1）寻找附近的世界并探索其宜居性； （2）绘制附近的行星系统，并了解它们所包含的世界的多样性； （3）通过扩展我们的紫外线覆盖范围，从我们自己的太阳系到外部星系进行新的探索，从我们自己的太阳系到外部星系。这项出色的天文台科学将通过竞争的GO计划选择，并将占HABEX主要任务的50％。首选的HABEX体系结构是4M，单轴离轴望远镜，在0.4微米处衍射限制，在L2轨道中。 Habex采用了两个星光抑制系统：一个冠状动脉和一个星际，每种都有自己的专用乐器。
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficiently to enable an affordable space-based telescope mission capable of discovering and characterizing Earthlike planets orbiting nearby bright sunlike stars in order to search for signs of habitability and biosignatures. Such a mission can also be equipped with instrumentation that will enable broad and exciting general astrophysics and planetary science not possible from current or planned facilities. HabEx is a space telescope with unique imaging and multi-object spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR. These capabilities allow for a broad suite of compelling science that cuts across the entire NASA astrophysics portfolio. HabEx has three primary science goals: (1) Seek out nearby worlds and explore their habitability; (2) Map out nearby planetary systems and understand the diversity of the worlds they contain; (3) Enable new explorations of astrophysical systems from our own solar system to external galaxies by extending our reach in the UV through near-IR. This Great Observatory science will be selected through a competed GO program, and will account for about 50% of the HabEx primary mission. The preferred HabEx architecture is a 4m, monolithic, off-axis telescope that is diffraction-limited at 0.4 microns and is in an L2 orbit. HabEx employs two starlight suppression systems: a coronagraph and a starshade, each with their own dedicated instrument.
