Questions & Answers

Q: What is the cause of the recent dip in brightness of Tabby's Star?

The current observations suggest that the dip in brightness is caused by dust, as it blocks certain frequencies more than others. This aligns with previous dimming events observed in the star.

Q: What is the long-term dimming trend of Tabby's Star, and why is it occurring?

Tabby's Star has been getting dimmer over the last century, but the cause remains unknown. Scientists are debating potential explanations for this long-term dimming trend.

Q: What is the significance of the nearby red dwarf in relation to Tabby's Star?

Recent research suggests that the red dwarf near Tabby's Star is not gravitationally bound to it. This finding has implications for the theory that the material blocking the light originated from the star's Oort cloud due to the red dwarf's disturbance.

Q: Are there any patterns or periodicity observed in the dimming events?

Some evidence points towards periodicity in the dimming events. In both Kepler data and photographic plates, there were dips separated by a 720-day period, suggesting the possibility of the same object passing in front of the star.

Summary & Key Takeaways

  • KIC 8462852, also known as Tabby's Star, has been quiet due to its position behind the sun during the winter but has recently started showing a significant dip in brightness.

  • Previous dimming events were believed to be caused by dust, and the current observations align with this explanation.

  • The star's overall dimming trend over the past century remains unexplained, and the presence of a nearby red dwarf raises questions about the origin of the material blocking the light.
