Astronomers have made a groundbreaking discovery, uncovering an unusual star that cycles in radio wave intensity and X-rays every 44 minutes. The star, known as ASKAP J1832, is part of a class of long period radio transients discovered in 2022. Unlike pulsars, which exhibit rapid variations multiple times a second, ASKAP J1832’s changes occur over tens of minutes.
Using data from NASA’s Chandra X-ray Observatory and the Square Kilometer Array Pathfinder (ASKAP) radio telescope, the team analyzed the star’s behavior. They found that ASKAP J1832’s X-ray signal also varies in a regular 44-minute cycle, making it the first time such an X-ray signal has been detected in a long period radio transient. This discovery sheds new light on the mysterious universe, leaving scientists eager to unravel more secrets of the cosmos.
