On the detectability of light on Dyson Sphere around white dwarf stars

Dyson Sphere around white dwarf stars can be targets in the search for techno-signatures. Even if a technological civilization was short lived, it could have left behind a source of Dyson Sphere that is detectable with JWST. We model different scenarios and show their detectability with different JWST's instruments using different physical properties. The results suggest that it may be possible to detect the light on Dyson Sphere.
