Tabby’s Star(KIC 8462852)

Tabby’s Star or Boyajian’s Star or WTF(Where’s the Flux?) Star or KIC 8462852 these all are name of a single star approximately located 1,470 light years(450 pc) far from earth in the constellation cygnus between the bright stars Deneb and Delta Cygni as part of the Northern Cross under Kepler Mission.

Tabby’s Star is one of biggest conspiracy of the 21st century. Tabby’s Star is famous for it’s unusual dips(dimming in brightness) in brightness.

Kepler Mission

How they found Tabby’s Star and Why it is abnormal???

Tabetha Boyajian is an assistant professor of Physics and Astronomy at LSU and a new addition to LSU college of Science Faculty.

Tabby’s Star is named on her after 27 January 2016, when she firstly Published a Document under Planet Hunters Citizen Scientist Group. It was Research Paper of 4 Years duration research did by Citizen Scientist on KIC 8462852 also known as TYC 3162-665-1 and 2MASS J20061546+4427248.

Here is the 4 year research data of KIC 8462852…

Here is the Research Document Published by Tabetha Boyajian on 27th January 2016…

This document shows how the Scientist Citizen Group discovered irregularity in KIC 8462852, Tabetha Boyajian did significant for this research that’s why later this star named on her.

Dip in brightness of Star is more regular at certain level when it happens at specific time duration with specific lose in brightness. Like Scientist of Max Planck Institute revealed that the sunlight is reduced by five times in past 9000 years it is also reported by Kepler Space Telescope. But in the case of KIC 8462852 the dip is very irregular and the decrease in brightness is at large level like around of 20% to 24%.

All Light Curve Events…

What cause dimming(most popular and possible theories)…..

There are only 2(two) main possibilities which may cause dip events in Tabby’s Star.

1. Dust

Some new researches found that in 2007 and 2014 this star brightened quite a bit. NASA’s Jet Propulsion Laboratory presented new researches that cites Dust as a possible factor that causes dimming.

In supports of this research University of Arizona, Tucson also stated about possibilities of uneven orbiting dust cloud or “Smoking Gun“. They said that researchers found less dimming in Infrared light of star than Ultraviolet light. That means there must be small dust particles like objects because if the size is large than it will block large amount of both Infra and Ultraviolet light which is not happening here as stated.

If we take this concept as satisfactory reason for dimming of star then here is one question still remaining unanswered. The dust concept is enough for the long term dimming events of star but what about short term event??? Usually as we know belts of dust in universe are greatly longer they can dim light for long time duration but not short time… So the researchers are thinking that the belt of comets may be the answer still not have any clue…

This study were led by Carnegie researchers and here is the research paper…

Same reason “Dust” but New research team with new concepts…

A research did by American Astronomical Society in Denver also supports the Dusty theory but has slightly different way than Carnegie Research…

In April 2017 Students of Thacher School, Ojai, California did some observatory researches on star’s mysterious dips in brightness.

Their researches shows that not only Dust is the reason for the dips but their are different types of dust passing from the front of the Star. The senior of School Yao Yin told to AAS that there may be different independent phenomena working at same time and cause to different effect long term and short term dimming. She said that there could be different types of dust either in size or chemical composition.

According to Eva Bodman, post doctoral researcher of Arizona State University told to AAS that any dust cloud obscuring star is extremely complex, there may be amorphous cloud.Analysis of light data from Boyajian’s star reveals the presence of clouds of very fine dust passing in front of it. This dust is different than our house’s Dust.

Bodman says that any more fine-grained dust near the star would have to be newly created because small grain sizes would be blown away by its stellar wind relatively quickly. But the star is still mystery…..

2. Dyson Sphere(Alien Mega-structure)

Now see why this concept is also disputable. The Tabby’s Star shows two kinds of dip events Long Term and Short Term. If we consider Dyson Sphere as the reason for the dips and it is absorbing energy from that star than How would you explain Long Term and Short Term event???

Here are some Research papers on Dyson Sphere…

This one given below is of Stockholm University…..

In every Research Paper you can see same type of possible models of Dyson Sphere. Every model has Uniform architecture (clean uniform covering only). It can Satisfy Long Term dips but what about Short Term???Means structure is uniform so light will also decrease at uniform level but there is no any extension or any extra layer at any specific part of the Sphere so how would you explain short term events???

So there is no perfect and clear explanation of both events and we don’t no enough about Dyson Sphere. In brief you can say we now nothing about Dyson Sphere instead of the name…..

So It is very difficult to say anything about it…..

Dust is more satisfactory view and NASA is also supporting this view…Let’s wait and watch what future brings for us…….
