Arnold, Forgan, and Korpela et al. 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 10 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 variability in depth… 

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 appreciate

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 for

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, rather than a natural cause such as cometary fragments in a highly elliptical orbit, we

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 bodies

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 the

Exoplanet transits as the foundation of an interstellar communications network

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.

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);

Possible Photometric Signatures of Moderately Advanced Civilizations: The Clarke Exobelt

This paper puts forward a possible new indicator of the presence of moderately advanced civilizations on transiting exoplanets. The idea is to examine the region of space around a planet where

A qualitative classification of extraterrestrial civilizations

A basic taxonomic approach to ETCs is taken and the implications of the new classification on E TCs observational patterns are investigated, including the existence of a Kardashev Type III ETC in the Milky Way and the weakens the Fermi paradox.

It is found that the maximum Galaxy colonization timescale is actually much shorter than previous work has found, and that many "sustainability" counter-arguments to Hart's thesis suffer from the monocultural fallacy.

Kepler planet candidate KOI-2700b (KIC 8639908b), with an orbital period of 21.84 hr, exhibits a distinctly asymmetric transit profile, likely indicative of the emission of dusty effluents, and

THE DETECTABILITY OF TRANSIT DEPTH VARIATIONS DUE TO EXOPLANETARY OBLATENESS AND SPIN PRECESSION

Knowledge of an exoplanet's oblateness and obliquity would give clues about its formation and internal structure. In principle, a light curve of a transiting planet bears information about the
