According to new information, what scientists assumed were planets are actually stars.

According to new research, scientists have identified at least three tiny stars masquerading as exoplanets.

NASA’s Kepler space telescope was the first to find the three, and maybe four, stars. They were categorized as outer planets at the time. According to a permit from the Massachusetts Institute of Technology (MIT), where most researchers are based, a new study reveals that its original classification may have been a case of misidentification.

Scientists have revised their estimates of the host planets’ stars. To determine the size of the potential exoplanets. This identified three questionable objects – known as Kepler-854b, Kepler-840b, and Kepler-699b – that are two to four times the size of Jupiter, making them too large to be planets. Instead, they should be categorized as tiny stars, according to the experts.

“The vast majority of exoplanets” Jupiter-sized or considerably smaller. In the announcement, Prajwal Niraula, the main author of the study and a graduate student in the Department of Earth, Atmospheric, and Planetary Sciences at MIT, said, “Twice the size of Jupiter seems suspicious.” “It couldn’t possibly be a bigger planet than that, which is what we discovered.”

The fourth hidden star, Kepler-747b, is approximately 1.8 times the size of Jupiter, making it equivalent to the largest confirmed exoplanet. However, because Kepler-747b is so far from its star, it seems unlikely that it will receive enough light to sustain itself as a planet of this size.

While this does not rule out Kepler 747b as a candidate exoplanet, scientists remain doubtful of its existence and planet categorization.

“Overall, this study adds to the current list of planets,” said Avi Shporer, co-author of the study and research scientist at MIT’s Kavli Institute for Astrophysics and Space Research, in a statement.

“People use this list to calculate the total number of planets. If you use a sample with a small number of intruders, your results may be erroneous. As a result, it is critical that the list of planets is not tainted.”

These stars’ true identities have been revealed as part of a bigger endeavor to find indicators of tidal distortion in exoplanet systems. The gravitational pull between two things can influence their forms.

When two objects are near together, their gravitational forces stretch the other into the shape of an egg or an ellipsoid.

The mass of the adjoining object determines the amount of distortion. According to the statement, researchers can tell whether they are looking at a binary star system or a star-planet system based on the strength of the tides detected.

When the scientists examined the most recent data from Kepler-854b, they discovered an elliptical signal that was too large to be created by a planet. Because the diameters of exoplanets are determined by comparing them to the size of the star they orbit, the scientists decided to examine data from the European Space Agency’s Space Star Mapping project, Jaya.

Indeed, Gaia data revealed that the star Kepler-854 is substantially larger than scientists had thought when a probable exoplanet was spotted. The astronomers recalculated and discovered that Kepler 854 b is three times the size of Jupiter. This suggests that Kepler-854b is a tiny star orbiting a larger host star, rather than an exoplanet.

Researchers have recalculated the size of other putative exoplanets circling stars whose estimations have altered drastically as a result of improved Gaia data.

“This was a massive scientific theory,” Niraula said in a statement. “We now have three bodies that aren’t planets, and the fourth is most likely not a planet.”

According to the statement, despite the fact that scientists have detected approximately 5,000 exoplanets so far, the team does not intend to make any further revisions to their existing exoplanet catalogs.

“This is a minor correction,” Sporer explained. “It stems from a better understanding of the stars, which is improving all the time.” As a result, the likelihood of the star’s radius being inaccurate is substantially lower. These misclassifications will not occur frequently.”
