NASA’s Chandra Finds Source of Star’s Mysterious Outbursts

Astronomers utilizing NASA's Chandra X-ray Observatory have identified the cause behind recurring bursts emanating from a large, volatile star. The research, detailed in an article released on Monday within The Astrophysical Journal, reveals a previously undetected companion object responsible for this phenomenon. This companion actively draws matter away from the primary star during each orbital cycle lasting approximately 113 days. As the companion pulls material, it generates intense X-rays detectable by Chandra’s instruments. Scientists believe that this ongoing process is fueling the star’s repeated and dramatic outbursts, offering new insights into stellar behavior.
