The authors of the theory are Tabeta Boyajian, Jason T. Wright and Peter Fukal. So far, there are a huge number of versions on this score that have a scientific background, but require additional data in order to confirm them.
The scientific publication The Astrophyscal Jornal Lettr reports that aliens may be on the celestial body, which is in close proximity to the star KIC 8462852 from the Cygnus constellation. Thanks to the Kepler telescope, scientists were able to capture an unusual glow that can be identified as gas or cosmic dust. However, there is a point that refutes the fact of natural formation of glow around KIC 8462852. The thing is that the star is not young. Jason T. Wright of the Penn State University Center for Exoplanets and Habitable Worlds in an article titled "Boyajian et al." reports that the star KIC 8462852 is a real challenge for world science. Like a puzzle, its characteristics contradict each other, if we take into account the laws of astrophysics, known to world science today. As part of the Planet Hunters project, it was possible to establish that the F-star does not have an infrared excess and radiative velocity variation. At the same time, KIC 8462852 is characterized by photometric behavior.
“The first is a set of daytime blackout events ('dips') of varying depth and duration that occurred sporadically during the main Kepler mission, but increased significantly in the last season of the Cygnus Field telescope observation. They are not at all similar to the exoplanetary transits that Kepler records in almost all respects, including their absence of periodicity, great depth (up to 22%), significant duration and asymmetric forms, Jason T. Wright quotes The Astrophyscal Jornal Lettr.
KIC 8462852, or, as it is also called the Boyajian's star, has all the similar characteristics to the "dipteran" stars, but such a classification is inherent in young celestial bodies, whose near-Earth fractions have stellar disks. However, as reported by Tabeta Boyajian, Boyajian's star is not young, which negates Jason T. Wright's speculation.
There is another indicator, the so-called long-term eclipse. Thus, the American researchers Monte and Simon report that during the Kepler mission, the star KIC 8462852 decreased by 3%. The researchers suggest that Boyajian's was much brighter earlier. In 1890, its glow was 15% stronger than its present state. That is why brightness, in principle, cannot be a statistically characteristic of a celestial body. “The absence of both a close warm material and a dense binary companion seems to leave only unlikely scenarios as solutions. In this key question, Wright and his associates drew on evidence from earlier studies of the object in the SETI community. Specifically that Kepler will be able to detect and distinguish artificial planetary structures or stars orbiting their target stars,if they exist,”writes The Astrophyscal Jornal Lettr.

It is quite natural that a priori the possible habitability of a celestial body attracted the attention of the media, who began to look for confirmation of the words of the authors of the theory in other specialists in the field of astrophysics. However, Wright and Sigurdsson clarify that this is far from the only explanation of the cosmic phenomenon. The thing is that the nature of interstellar space depends on its structure and those space objects that fill it. "Makarov and Goldin reached a similar conclusion, based on an analysis of Kepler-level data at the pixel, which suggests that some of the dips and other characteristics of the Kepler light curves are due to light pollution from nearby stars," the study authors added.
Many experts from the Center for Exoplanets and Habitable Worlds at Penn State University believe that the star KIC 8462852 could represent a new kind of space object and really uncover the mystery of habitability, where the glow is an artificially created phenomenon. Their opponents suggest that this is an exoplanet, on which there are no signs of life. The glow, in turn, may indicate processes that are simply unknown to world science.
Researcher Petr Fukal, together with his team of experts, also began to study the issue of studying the star KIC 8462852, writes the scientific journal A. S. NOVA. For several years, the author of this theory observed the nature of the brightness of the celestial body and came to the conclusion that every year the Boyajian's star decays at a rate of 0.1-1%. The researcher explains this process as the magnetic activity of differential rotation (sporadic changes in the composition of the photosphere and just a random change in convective efficiency) or by the fact that the object is in the last stage of its convective life.
It is noteworthy that today the world community has not been able to find an analogue of KIC 8462852, which is why it is very difficult to study the nature of this phenomenon. However, scientists have high hopes for Boyajian's future science projects. “Perhaps our further observations will finally reveal the mystery about the habitability of Boyajian's star,” writes A. AS. NOVA.
