• Citizen Science: Amateur astronomers and citizen scientists have actively participated in monitoring Tabby's Star's dimming events.

• Exoplanet Hypothesis: One of the leading natural explanations for the dimming is the presence of a group of exoplanets with irregularly shaped orbits that occasionally pass in front of the star.

• Non-Uniform Dimming: The irregular dimming pattern makes it challenging to attribute the phenomenon to a single cause.

• Subsequent Observations: Tabby's Star continues to be a subject of ongoing research and observations to understand its unique behavior.

• The "Wow!" Signal: The star's unusual behavior has drawn comparisons to the famous "Wow!" signal, which was an intriguing radio signal detected in 1977.

• Solar Activity: Solar activity, similar to sunspots on our Sun, has been proposed as another potential cause of Tabby's Star's dimming.

• Comet Fragments: Researchers have suggested that the dimming could be due to the presence of comet fragments or irregularly shaped dust clouds.

• Rapid Rotator: Tabby's Star is known for its rapid rotation, completing one rotation in just 5.5 hours.

• Variability in Dimming: The star's dimming events can vary in duration and depth, making predictions and explanations more complex.

• Kepler Data Anomalies: Tabby's Star is not the only star to exhibit unusual dimming patterns in the Kepler dataset, but it is one of the most notable cases.

• Spectroscopy Studies: Spectroscopic analysis of the star's light provides insights into its composition, temperature, and chemical elements.

• Sun-like Nature: Despite its peculiar dimming behavior, Tabby's Star shares many characteristics with our Sun.

• Infrared Excess: Infrared observations have revealed an excess of infrared radiation, which could be attributed to dust or circumstellar material.

• Citizen Science Project: The Planet Hunters project allowed thousands of citizen scientists to participate in the analysis of Kepler data, leading to the discovery of Tabby's Star.

• Controversial Nature: Tabby's Star has been a topic of debate and controversy within the scientific community.

• Stellar Wind: One theory suggests that the star's unusual dimming could be caused by changes in its stellar wind.

• Multiple Hypotheses: Various hypotheses have been proposed to explain Tabby's Star's behavior, including the idea of a large group of comets passing in front of the star.

• Far-Infrared Data: Far-infrared data from the Herschel Space Observatory contributed to our understanding of the star's dust environment.

• Infrared Excess vs. Megastructure: The debate between the infrared excess and the megastructure hypothesis continues to be a point of contention.

• Non-Kepler Observations: Follow-up observations have been conducted with ground-based telescopes to study the star's dimming events.

• Dust Ring: Some research suggests the presence of a dust ring around Tabby's Star, potentially causing the dimming.

• Inconsistent Dimming: The star's dimming patterns are not always consistent in duration or depth, adding to the mystery.

• Natural or Artificial: The question of whether the dimming is natural or artificial remains unanswered.

• Light Travel Time: Due to its distance from Earth, the light we observe from Tabby's Star today actually left the star around the time the Roman Empire was at its height.

• Amateur Contributions: Amateurs have made significant contributions to understanding the star, demonstrating the power of citizen science.

• Hubble Observations: The Hubble Space Telescope has been employed to study Tabby's Star's properties and surroundings.
