“#New AI tool that detects star flares could help us find habitable planets<\/strong>”
\n<\/p>\n

\n A new AI system that detects flares erupting from stars could help astronomers find habitable planets, according to the tool\u2019s inventors.<\/p>\n

The\u00a0neural network\u00a0detects the light patterns of a stellar flare \u2014 which\u00a0can incinerate the atmospheres of planets forming nearby. The frequency and location of the flares can therefore indicate the best places to search for habitable planets.<\/p>\n

Astronomers normally look for the flares through a time-consuming process of analyzing measurements of star brightness by eye. The AI tool could make their\u00a0work faster and more effective.<\/p>\n

The researchers\u00a0trained the neural network on a dataset of identified flares and not-flares, and then app<\/a>lied it to a dataset of\u00a0more than 3,200 stars. It discovered more than 23,000 flares across thousands of young stars.<\/p>\n

The researchers\u00a0found that stars similar to our sun only have a few flares, which seem to decrease in number after around 50 million years.<\/p>\n

\u201cThis is good for fostering planetary atmospheres \u2013 a calmer stellar environment means the atmospheres have a better chance of surviving,\u201d said<\/a>\u00a0Adina Feinstein, a University of Chicago graduate student and first author on the paper.<\/p>\n

However, cooler stars called red dwarfs tended to have more frequent flares, which could make it hard for the planets they host to retain any atmosphere.<\/p>\n

The researchers now plan to modify the neural network so it can look for planets close to young stars.<\/p>\n

\u201cThis will hopefully lead to a \u2018rise of the machines\u2019 where we can apply machine learning algorithms to find a bunch of exciting new planets using the same methods,\u201d\u00a0said UNSW Sydney\u2019s Dr Ben Montet, co-author of the study.<\/p>\n
