Arnold (2005), Forgan (2013), and Korpela et al. (2015) noted that planet-sized artificial structures could be discovered with Kepler as they transit their host star. We present a general discussion of transiting megastructures, and enumerate ten potential ways their anomalous silhouettes, orbits, and transmission properties would distinguish them from exoplanets. We also enumerate the natural sources of such signatures. Several anomalous objects, such as KIC 12557548 and CoRoT-29, have… Expand
A Cloaking Device for Transiting Planets
The transit method is presently the most successful planet discovery and characterization tool at our disposal. Other advanced civilizations would surely be aware of this technique and appreciateExpand
Optical SETI Observations of the Anomalous Star KIC 8462852
To explore the hypothesis that KIC 8462852's aperiodic dimming is caused by artificial megastructures in orbit (Wright et al. 2015), rather than a natural cause such as cometary fragments in a highlyExpand
Disrupted exoplanet systems in the SuperWASP Archive
The aim of this research project has been to search for disrupted or disintegrating exoplanets; this search has been carried out using archival data from the Super-WASP (Wide Angle Search forExpand
Possible Photometric Signatures of Moderately Advanced Civilizations: The Clarke Exobelt
This paper puts forward a possible new indicator for the presence of moderately advanced civilizations on transiting exoplanets. The idea is to examine the region of space around a planet whereExpand
Mysterious eclipses in the light-curve of KIC8462852: a possible explanation
Apart from thousands of `regular' exoplanet candidates, Kepler satellite has discovered a few stars exhibiting peculiar eclipse-like events. They are most probably caused by disintegrating bodiesExpand
Astroengineering, Dysonian SETI, and naturalism: A new Catch-22
Abstract A methodological problem is inherent in any discussion of extraterrestrial engineering and its detectability: how to distinguish detection signatures of such astroengineering from “natural”,Expand
Secular dimming of KIC 8462852 following its consumption of a planet
The Kepler-field star KIC 8462852, an otherwise apparently ordinary F3 main-sequence star, showed several highly unusual dimming events of variable depth and duration. Adding to the mystery was theExpand
Kepler: A Brief Discussion of the Mission and Exoplanet Results
INTRODUCTIONThe Kepler Mission was a PI-led NASA Discovery mission designed to determine the frequency of Earth-size and larger planets in the habitable zone (HZ) of other stars (i.e., exoplanets);Expand
Exoplanet transits as the foundation of an interstellar communications network

TLDR
Monte Carlo Realization simulations of the establishment and growth of a network of interconnected civilizations, and analyse its properties in the context of graph theory find that at any instant, only a few civilizations are correctly aligned to communicate via transits. Expand
The Search for Extraterrestrial Intelligence in Earth's Solar Transit Zone.
TLDR
This work explores Earth's transit zone (ETZ), the projection of a band around Earth's ecliptic onto the celestial plane, where observers can detect Earth transits across the Sun, and finds that about 10(5) K and G dwarf stars should reside within the rETZ. Expand
