该3.5米分段镜机器人空间望远镜核心任务为致密天体时域科学，采用不同分辨率光谱仪跟踪暂现源等，结合内外监测实现相关科学目标。
AI 中文摘要
孤立致密天体保留了天基无狭缝摄谱仪的点源分辨能力，基线波长范围为0.2--1.5μm。规划基线采用R≃1000用于宽且暗的暂现源光谱，并预留R≃5000的可选波段用于吸积盘轮廓、速度结构及精密线比率研究。原始R≃5000数据分箱至更低分辨率后可测量宽特征。快速响应光谱学从数小时到数天跟踪引力波对应体与千新星；对矮新星和致密双星的重复光谱观测追踪吸积状态与轨道相位，对白矮星的连续成像测量脉动频率。该项目结合任务内监测与外部警报，包括KGMT暂现源探测。仪器研究必须将校准后的通量保持至2.70μm，评估3.0μm的工作波段边缘，保留2.5μm作为正式工程退出行；中红外成像不纳入已采用的致密天体基线。
英文摘要
An isolated compact object retains the point-source resolving power of the space-based slitless spectrograph. The baseline wavelength range is 0.2--1.5 $μ$m. The planning baseline uses $R \simeq 1000$ for broad and faint transient spectra and reserves selectable bands at $R \simeq 5000$ for accretion-disk profiles, velocity structure, and precision line ratios. Broad features can be measured after binning the native $R \simeq 5000$ data to lower resolution. Rapid-response spectroscopy follows gravitational-wave counterparts and kilonovae from hours to days. Repeated spectra of dwarf novae and compact binaries trace accretion state and orbital phase, while uninterrupted imaging of white dwarfs measures pulsation frequencies. The program combines mission-based monitoring with external alerts, including KGMT transient detections. The instrument study must preserve calibrated throughput to 2.70 $μ$m and evaluate a 3.0 $μ$m operational band edge, with 2.5 $μ$m retained as the formal engineering off-ramp. Mid-infrared imaging is not part of the adopted compact-object baseline.
CommentsRevised to focus the compact-object program on repeated optical/NIR spectroscopy, R~5000 line-profile measurements, and white-dwarf pulsations, with clearer roles for external alerts and complementary data
