Tabby's Star Unusual Light Fluctuations

Tabby's star was observed to have unusual light fluctuations, and a dimming of 22 percent, according to data from the Kepler Space Telescope.
The fluctuations are unlike any other star observed in our galaxy.
This star is 50 percent larger than our sun and 1,000 degrees hotter. It is located 1,470 light years from Earth.
Tabby's star is classified as an F star, but it showcases a strange series of photometric dips, or fluctuations in intensity of light.
A scientific paper published by astronomer and professor Tabetha S. Boyajian, announced the discovery in 2015.
The star was first observed in 1890, but Boyajian first noticed the fluctuations in 2015.
Hypothesized causes of the dimming of Tabby's Star include:
A circumstellar dust ring
A cloud of disintegrating comets
It is a young star with coalescing material around it
A planetary debris field
Consumption of a planet by Tabby's star
A large planet with oscillating rings is dimming the light
The cooling of its photosphere
Chunks of an Exomoon's dusty outer layers of ice, gas, and rock dimming the view
Astronomers claim that Tabby's star is hundreds of millions of years old, and that surrounding dust could not have lasted that long.
Therefore, astronomers continue to propose causes of new dust and gas to block Tabby's star brightness.
However, in a young universe creationists model there is not so much of an issue, being only thousands of years old.
Tabby's star has been determined according to astronomical data to be dimming since 1890, which is over 100 years. Explanations of why it has been dimming for so long are difficult.
