Recent astrophysical research proposes a methodology for detecting Dyson swarms—engineered arrays of solar collectors—by analyzing anomalous infrared emissions and stellar temperature shifts.

最近的天體物理研究提出了一種方法，透過分析異常的紅外線發射與恆星溫度偏移，來偵測戴森球群（Dyson swarms）——即一種經過設計的太陽能收集陣列。

The theoretical framework for stellar energy capture, initially postulated by Freeman Dyson in 1960, has evolved from the concept of a solid shell to a 'swarm' of independent orbiting structures. This transition is necessitated by the prohibitive material requirements associated with solid spheres. Research conducted by Amirnezam Amiri of the University of Arkansas identifies red dwarfs and white dwarfs as optimal hosts for such structures. Red dwarfs are characterized by their ubiquity and extreme longevity, while white dwarfs offer high density and stable energy output, both of which minimize the requisite construction scale.

恆星能量捕捉的理論框架最初於 1960 年由 Freeman dyson 提出，已從實心殼的概念演變為由獨立軌道結構組成的「球群」。這種轉變是因為實心球體所需的材料要求過高而不可行。阿肯色大學的 amirnezam amiri 進行的研究指出，紅矮星與白矮星是此類結構最理想的宿主。紅矮星的特點是普遍存在且壽命極長，而白矮星則提供高密度與穩定的能量輸出，兩者均能將所需的建設規模降至最低。

Detection of these technosignatures relies upon the utilization of the Hertzsprung-Russell (H-R) diagram. A Dyson swarm would absorb visible radiation and re-emit it as infrared heat, resulting in a significant reduction in apparent surface temperature—potentially from 3,000K to 50K in the case of red dwarfs. Such a shift would place the object in a region of the H-R diagram devoid of naturally occurring stars. Furthermore, the absence of silicate emissions, typical of natural circumstellar dust disks, would indicate a 'clean' spectrum consistent with engineered radiator panels. Additionally, the orbital dynamics of a swarm would likely induce non-natural luminosity fluctuations.

偵測這些技術標誌依賴於赫羅圖（h-r diagram）的運用。戴森球群會吸收可見光輻射並將其重新發射為紅外線熱能，導致表面溫度顯著降低——以紅矮星為例，可能從 3,000k 降至 50k。這樣的偏移將使該天體處於赫羅圖中不存在天然恆星的區域。此外，若缺乏天然恆星周圍塵盤典型的矽酸鹽發射，將顯示出一個與人造輻射面板一致的「乾淨」光譜。此外，球群的軌道動力學可能會引起非自然的亮度波動。

Institutional efforts to identify these anomalies include the utilization of the James Webb Space Telescope and the Wide-field Infrared Survey Explorer (WISE). Project Hephaistos recently screened approximately five million stars, identifying seven initial candidates associated with red dwarfs. Following the discovery that one signal was the result of a background supermassive black hole, five candidates remain under investigation.

相關機構識別這些異常現象的努力包括利用詹姆斯·韋伯太空望遠鏡與廣域紅外線巡天探測器（wise）。hephaistos 計畫最近篩選了約五百萬顆恆星，識別出七個與紅矮星相關的初步候選對象。在發現其中一個訊號是由背景超大質量黑洞引起後，目前仍有五個候選對象在調查之中。

Current astronomical efforts are focused on differentiating these five remaining candidates from natural cosmic phenomena using infrared spectral analysis.

目前的天文研究重點在於利用紅外線光譜分析，將剩餘的五個候選對象與天然宇宙現象區分開來。
