Astronomers Identify ASKAP J1745 as Key to Understanding Mysterious Cosmic Signals
Astronomers have identified a new source of repeating radio bursts, known as ASKAP J1745, which originates from a pair of stars spiraling around each other. This discovery is significant as it provides a clearer understanding of long-period transients, mysterious bursts of radio signals that have puzzled scientists for years. ASKAP J1745 is unique because it emits both radio and X-ray bursts with each orbit, a phenomenon observed using various telescopes. This new information is likened to the Rosetta stone, offering insights into the nature of these cosmic signals. The study, published in Nature Astronomy, suggests that ASKAP J1745 is a 'cataclysmic variable,' a system where a white dwarf star accretes material from a companion star, leading to the observed bursts.
