本文介绍VLTI上Asgard仪器套件(含HEIMDALLR、Baldr、BIFROST、NOTT)的集成进展,第一阶段已完成,旨在提升近红外高角分辨率与高对比度观测能力。
中文摘要 AI 辅助
ESO的VLTI在使用高角分辨率仪器进行天体物理学发现方面有着创纪录的历史。其最新的访客仪器——Asgard仪器套件,是进一步提升该设施潜力(尤其是在近红外波段)的关键之一。该套件包含四个原生协作的仪器:HEIMDALLR,一个K波段条纹跟踪器、波前校正器和K波段恒星干涉仪,三者共用同一套光学元件;Baldr,一个H波段泽尼克波前传感器;BIFROST,一个Y-J-H波段光子组合器,其主要科学目标是研究恒星和行星系统的形成过程与性质;以及NOTT,一个用于对年轻行星系统成像的L波段零差干涉仪。每台仪器都在其各自的科学目标上承诺了重大进展,这些进展与其技术挑战和技术创新规模相当。Asgard的集成计划分三个阶段进行。第一阶段(HEIMDALLR和Baldr的集成与调试)已成功完成。在本文中,我们展示了Asgard集成当前进展的概述、HEIMDALLR在天空调试的初步结果,以及Asgard为更广泛社区服务的未来步骤和观测政策。
英文摘要
ESO's VLTI has a history of record-breaking discoveries in astrophysics using high-angular resolution instrumentation. Its latest visitor instrument, the Asgard instrumental suite, is one key to further enhance the potential of the facility, particularly in the very near-infrared. It comprises four natively collaborating instruments: HEIMDALLR, a K-band fringe tracker, wavefront corrector and stellar interferometer in K band, with the same optics; Baldr, an H-band Zernike wavefront sensor; BIFROST, an Y-J-H-band photonic combiner whose main science case is studying the formation processes and properties of stellar and planetary systems; and NOTT, an L-band nulling interferometer for imaging young planetary systems. Each of these instruments promise significant advances in their respective science goals that scale with their technical challenges and technology innovations. The integration of Asgard is planned in three phases. The first one (integration, commissioning of HEIMDALLR and Baldr) is successfully done. In this paper, we show an overview of the current progress of the integration of Asgard, the first results of the on-sky commissioning of HEIMDALLR and the future steps and observing policies for Asgard to serve the broader community.
