What is TESS?
TESS, short for the Transiting Exoplanet Survey Satellite, is a NASA mission designed to monitor the brightness of stars and detect exoplanets as they pass in front of their host stars, causing periodic dimming. Launched in 2018, TESS has expanded our knowledge of distant worlds and complex star systems.
The Discovery of TIC 290061484
On October 2, 2024, NASA announced that TESS had discovered TIC 290061484, a tightly bound triple-star system unlike any previously observed. This discovery was made possible through the combined efforts of professional astronomers and dedicated citizen scientists.
Details of the Triple-Star System
Orbital Characteristics
The inner pair of stars in TIC 290061484 orbit each other every 18 Earth days, while the third star orbits this pair every 25 days. The entire system could fit comfortably within the orbit of Mercury around our Sun, making it exceptionally compact.
Stellar Composition
The system comprises two closely orbiting stars with a third star orbiting further out. The precise masses, sizes, and temperatures of these stars are still being studied, but their stable configuration offers a unique opportunity for astronomers to understand multi-star systems better.
Why This Discovery is Significant
This system’s tight orbit challenges previous models of star formation and stability. It suggests that such configurations may be more common than previously thought, offering new insights into the dynamics of multi-star systems.
The Role of Citizen Scientists
Citizen scientists played a crucial role in this discovery through the now-closed Planet Hunters project, which ran from 2010 to 2013. These amateur astronomers helped filter data and identify intriguing signals, showcasing the power of collaborative science.
How TESS Identified the System
TESS monitors the brightness of stars to detect periodic dips caused by transiting objects. In this case, the team used machine learning to analyze vast amounts of data and identify the strobing effect caused by the stars eclipsing each other.
Potential for Future Discoveries
The discovery suggests that many more such systems may exist across the Milky Way. With advancements in technology and future missions like the Nancy Grace Roman Space Telescope, we may uncover even more tightly bound star systems.
Implications for Exoplanet Research
Triple-star systems like TIC 290061484 present unique challenges for exoplanet detection due to their complex gravitational interactions. However, understanding these systems can provide valuable insights into planet formation and stability.
Challenges in Studying Triple-Star Systems
Studying such tightly bound star systems is challenging due to their complex gravitational interactions and the need for precise measurements of their orbits, masses, and compositions.
The Fate of TIC 290061484
The stability of TIC 290061484 won’t last forever. As the twin stars age and expand, they will eventually merge, triggering a supernova explosion in about 20 to 40 million years. This event will drastically alter the system’s dynamics.
The Promise of the Nancy Grace Roman Space Telescope
Set to launch in May 2027, the Nancy Grace Roman Space Telescope will provide high-resolution images of space, enabling detailed studies of tightly packed star systems like TIC 290061484. Its advanced capabilities will help us uncover new celestial phenomena.
Citizen Science and Machine Learning
The collaboration between citizen scientists and machine learning algorithms has proven invaluable in this discovery. By combining human intuition with advanced technology, we can analyze vast datasets more efficiently and uncover hidden patterns.
