To quote Sherlock Holmes - "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." Obviously this dust is not going to simply disappear. Therefore, something happened during the 27 year period when we were not looking at TYC 8241 2652.

I am reminded of when Galileo first discovered Saturn's rings, even though he did not know what they were, he observed that they suddenly disappeared two years after discovering them. What he did not know is that the rings were still there, he was just seeing them edge-on, which made them appear to disappear.

Unfortunately, I am not able to find out any information about the star TYC 8241 2652. The search engines are saturated with the news of the missing dust. I did find one article from NASA describing TYC 8241 2652 as a "young sun-like star."

NASA - The Mysterious Case of the Disappearing Dust

Since this dust could not simply disappear there are only three possible explanations:
  1. The dust was consumed by the young star; or
  2. The dust was blown out, away from the young star; or
  3. The dust has not moved and the current information is somehow erroneous (like Galileo).
I wish I could find more information about the star itself, that could explain things. For example, when there is enough dust and gas to compress enough to reach two million degrees Kelvin it becomes a proto-star. When temperatures reach 18 million degrees Kelvin the proto-star becomes hot enough to fuse hydrogen, and a star is born. When nuclear fusion occurs solar winds are also created, and those solar winds could, theoretically, have blown out the extra gas and dust that did not comprise the star.

If there was gas and dust surrounding the young star in 1983, and it is suddenly missing since 2010, then there would be a noticeable increase in the star's apparent magnitude. Yet I can find nothing about the star's magnitude in any of the articles, before or since. It is like they are only focusing on the disappearance of the dust and gas, and are completely ignoring the most obvious culprit.
