Scientists have developed a new method that could revolutionize how we find and classify new planets that are very far from Earth. They detected exoplanets using machine learning, a field of artificial intelligence.
A recent study by a team of researchers at the University of Georgia showed that machine learning can examine protoplanetary disks, the gas around newly formed stars, to correctly determine whether exoplanets are present. rice field. The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.
“We used conventional methods to identify the planets, but our model told us to run those simulations and showed us exactly where the planets are,” the study said. Lead author Jason Terry said in a release.
“Applying the model to a series of older observations identified a disk that had already been analyzed but was not known to contain planets. As with previous discoveries, we performed simulations of the disk. and discovered that planets could re-form, making observations.”
According to Terry, the model suggests the presence of a planet, indicated by several images that strongly highlight certain regions of the disk that were found to have characteristic signatures of the planet – near the planet. Abnormal deviations in gas velocity.
“This is an incredibly exciting proof-of-concept. From previous work, we knew that machine learning could be used to find known forming exoplanets.” “Now we are confident that we can use it to make completely new discoveries.”
“This demonstrates the ability of our models, and machine learning in general, to quickly and accurately identify important information that people may miss. Subsequent theoretical insights can be dramatically sped up,” said Terry.
“It only took about an hour to analyze that entire catalog and find strong evidence of a new planet at a particular location, so as the dataset grows ever larger, more important locations for these types of techniques become apparent. I think there is.”
