Record-Breaking Stellar Trio Discovered by NASA's TESS and AI

Discovery of TIC 290061484: A Record-Breaking Stellar Trio

In a groundbreaking collaboration between professional astronomers, amateur scientists, and artificial intelligence, a unique triple star system named TIC 290061484 has been discovered using NASA's Transiting Exoplanet Survey Satellite (TESS) 1

Unprecedented Orbital Configuration

The newly discovered system consists of two twin stars orbiting each other every 1.8 days, with a third star circling the pair every 24.5 days 3

3

. This configuration is remarkably compact, with all three stars fitting within an area smaller than Mercury's orbit around the Sun 4

. The previous record for the shortest outer orbital period in a triple star system was 33.02 days, making TIC 290061484 significantly faster 1

Collaborative Discovery Process

The discovery of TIC 290061484 was made possible through a unique combination of technologies and human expertise:

1. TESS satellite observations captured flickers of starlight caused by the stars eclipsing each other 1

Scientific Significance and Future Research

The discovery of TIC 290061484 offers valuable insights into stellar formation and evolution. Veselin Kostov, a research scientist at NASA's Goddard Space Flight Center, emphasized the importance of the system's edge-on configuration, which allows for precise measurements of the stars' orbits, masses, sizes, and temperatures 2

.

While the system is believed to be stable for millions of years due to its flat orbital plane, it is expected to undergo dramatic changes in the future. In approximately 20 to 40 million years, the inner stars are predicted to expand, merge, and trigger a supernova explosion 1

Future Exploration with the Nancy Grace Roman Space Telescope

Astronomers are eager to discover even more compact triple star systems, and the upcoming Nancy Grace Roman Space Telescope is expected to play a crucial role in this search 4

. The Roman telescope will provide much more detailed images than TESS, potentially revealing:

1. Triple star systems with even shorter orbital periods
2. Larger groups of eclipsing stars orbiting each other
3. Never-before-seen categories of stellar systems and objects 2
