摘要

DECIGO 是日本未来的一个空间引力波探测项目。为了执行各种科学任务，包括以通过探测原始引力波验证宇宙膨胀为主要目标，DECIGO 被设计为在 0.1 到 10 Hz 的频带内具有高灵敏度，臂长为 1000 公里。此外，DECIGO 项目还在这些臂中使用了法布里-珀罗特腔。在本文中，我们仔细研究了法布里-珀罗腔对推动该项目的意义，重点是观测宇宙膨胀产生的引力波和双紧凑恒星系统作为指标的可能性。结果表明，使用法布里-珀罗腔对探测引力波极为有利，有望为引力波天文学打开一扇新窗口。

Significance of Fabry-Perot Cavities for Space Gravitational Wave Antenna DECIGO

DECIGO is a a future Japanese project for the detection of gravitational waves in space. To conduct various scientific missions, including the verification of cosmic inflation through the detection of primordial gravitational waves as the main objective, DECIGO is designed to have high sensitivity in the frequency band from 0.1 to 10 Hz, with arms of length 1000 km. Furthermore, the use of the Fabry-Perotcavity in these arms has been established for the DECIGO project. In this paper, we scrutinize the significance of the Fabry-Perot cavity for promoting this project, with a focus on the possibility of observing gravitational waves from cosmic inflation and binary compact star systems as indicators. The results show that using the Fabry-Perot cavity is extremely beneficial for detecting them, and it is anticipated to enable the opening of a new window in gravitational wave astronomy.
