Astronomers discovered a world with 3 suns, it was 4

Solar system The one we live in is unique from our point of view because life exists in this tiny part of the universe in the Milky Way Galaxy, supported by the existence of this life Sunday Around which all the planets revolve.

Imagine there is a solar system with four suns. The system was squeezed tightly together, and astronomers estimated that the system contained four stars until three other suns ate a quarter.

Astronomers have discovered for the first time a unique system in which two binary stars are orbiting each other and a larger star is orbiting both. This world they call HD 98800 is located 150 light years away in the constellation TW Hydra.

Binary stars orbit each other in a day, just like the Earth completes one revolution in 24 hours. The two suns combined, have a mass 12 times the mass Sunday We.

“As far as we know, this is the first of its kind ever detected. We know a lot about tertiary star systems, but they are usually much less massive. The mass in these triple systems But the stars are very close to each other. On the other hand, it is a compact system,” said Alejandro Vigna-Gómez of the Niels Bohr Institute at the University of Copenhagen. india today,

Alejandro is collaborating with his research colleague Bin Liu from China to find an answer to the question of how this unique combination of binary stars and massive rotating stars formed.

Researchers are baffled by the existence of a third star in this system, weighing 16 times the mass of our Sun, with an inner circular orbit that orbits the two stars six times each year.

This system, due to its high brightness, was first discovered by a community of amateur astronomers who took data from NASA’s Transiting Exoplanet Survey Satellite Observatory. At first, they thought it was an anomaly and cautious professional astronomers later confirmed that it was a unique triple star system.

The two researchers then coded the data and ran it 100,000 iterations on a supercomputer to assess the most likely outcome of this scenario.

“We now have a model of the most likely scenario for this unique system. But one model alone is not enough. And there are two ways to prove or elaborate on our theory of this formation. One is to study the system in detail and To do a statistical analysis of other stellar populations,” Alejandro said.

Alejandro explains, “If we go into the system in detail, we have to rely on the expertise of an astronomer. We’ve already made preliminary observations, but we still have to look at the data and make sure we get a good interpretation of it.” Do it.”

The two researchers are currently using telescopes and observatories around the world to observe this unique system.
