In 2012, it was found that the brightness of this object was reduced by 95%.
Scientists have found a new star whose brightness varies in an unusual way. The most famous object is the so-called "Star Tabby", whose astronomers have explained the different hypotheses, up to the astro-engineering structures of extraterrestrials. The results are published on the preprints website arXiv.org.
This writes the Chronicle.info with reference to rambler.ru.
The "Kepler" space observatory, designed to search for exoplanets, has detected unusual fluctuations in the brightness of star KIC 8462852, more commonly known as "Star Tabby" – named after one of the discoverers, Tabitha Boyajian. This star and this hot sun, but above all interesting because of its radiance mysteriously changed: it faded and ignited without any regularity. Scientists have proposed many reasons for the phenomenon, including, for example, extraterrestrial megastructure, huge clouds of dust and huge swarms of comets.
In the new work, astronomers write about another star called VVV-W-07, whose brightness is also strange. Observations were made from 2010 to 2018, are not allowed to reveal some regularities of changes in brightness; however, it is sometimes reduced by 80%, while the Star Tabby is only 20%, which is however a lot for such projects. fixtures.
There is another star with an unusual brightness change – J1407, which is also called "an object of Mamaduka" on behalf of the discoverer Eric Mamajek. In 2012, it was found that the brightness of this object was reduced by 95%, but these changes can be attributed to the periodic pattern, which allowed to explain the presence of planets satellites or brown dwarfs with an incredibly extensive ring system. Hundreds of times larger than those of Saturn.
The discovery of several stars with unusual brightness variations suggests that they are relatively common. However, some astronomers doubt the true similarities VVV-W-07 and KIC 8462852. The fact that the Star Tabby is quite old and should not be a private activity, while the young VVV-W-07 and therefore of big changes in brightness can be related to internal processes. Along the line of sight of VVV-W-07, there is also much more galactic dust, which also creates a significant distortion in the world. The authors of this new publication hope to obtain observation time on large telescopes to obtain much more detailed information on radiation on the object.
