ArgusSpec将是一个快速响应、低分辨率的光谱跟踪系统。几乎完全由现成的组件制成，包括一个中等孔径（16英寸）。利用Ritchey-Chretien望远镜、低噪声CMOS探测器、低分辨率（R~100）摄谱仪和快速回转（50 deg/s）支架，ArgusSpec将在几十秒内开始观测明亮的瞬变事件（mV ≤ 13）。ArgusSpec将使用来自Evryscope、Argus Pathfinder和计划中的完整Argus阵列的全天瞬变警报;后两个系统提供迄今为止最快的光学瞬变警报。到目前为止，高节奏的天空在很大程度上是光谱学无法到达的。例如，来自活跃恒星的大耀斑对绕轨道运行的系外行星有巨大的影响，但由于其短时间尺度的演变，因此很难进行光谱跟踪。位于活跃恒星宜居带的行星将受到耀斑和超级耀斑（能量≥ 1033 erg）的影响，以及相关的高能粒子发射，这可能会剥夺行星的大气层并带来大量的紫外线通量;这可能会对行星表面的任何生命造成毁灭性的影响。目前还没有一个系统的光谱调查的能量耀斑事件在广泛的恒星质量;几乎所有的大型耀斑观测光谱已从一个小样本的活跃中M星通过凝视运动。ArgusSpec将首次建立一个来自整个夜空的超级耀斑光谱库，允许对其黑体演化和形态进行统计约束。在这里，我们介绍了ArgusSpec的设计，项目状态和科学驱动因素。
ArgusSpec will be a fast-response, low-resolution spectroscopic follow-up system. Built almost entirely from off-the-shelf components, including a medium-aperture (16-in.) Ritchey-Chretien telescope, a very-low-noise CMOS detector, a low-resolution (R~100) spectrograph, and a fast-slew (50 deg/s) mount, ArgusSpec will begin observations of bright transient events (mV ≤ 13) within tens of seconds of detection. ArgusSpec will use all-sky transient alerts from the Evryscope, the Argus Pathfinder, and the planned full Argus Array; the latter two systems giving the fastest alerts for optical transients to date. Until now, the high-cadence sky has been largely inaccessible for spectroscopy. For example, large flares from active stars have dramatic impacts on orbiting exoplanets, but are difficult targets for spectroscopic follow-up due to their short-timescale evolution. Planets in the active stars’ habitable zones will be impacted by flares and superflares (energies ≥ 1033 erg), and associated high-energy particle emissions, which could strip the planet of its atmosphere and impart massive amounts of ultraviolet flux; this could be devastating to any life on the planet’s surface. There has not been a systematic spectroscopic survey of energetic flaring events across a wide range of stellar masses; almost all large flares observed spectroscopically have been from a small sample of active mid-M stars through staring campaigns. For the first time, ArgusSpec will build a library of superflare spectra from across the night sky, allowing for statistical constraints to be placed on their blackbody evolution and morphology. Here we present the design, project status, and science drivers of ArgusSpec.
