Anomalous Variability of Dyson Megastructures

Abstract

In the framework of the approach of Dyson megastructures, by assuming that a super-advanced civilization exists and is capable of constructing a ring-like megastructure around their host star, we have considered the observational signatures of cold (300 K) and hot (4000) K astro-engineering to answer the question: are the modern facilities capable to detect theoretically predicted fingerprints? By implying the spectral resolving power and the radial velocity methods it has been shown that the oscillation of the rings might be detected as anomalous variability of the megastructures.
