A dead “vampire” star is feeding on a nearby companion and expelling cannonballs and its behaviour has left astronomers stunned. The dead star is located around 4,500 light-years away and, until now, has baffled astronomers with its unusual behaviour. It is a rapidly spinning neutron star, otherwise known as a pulsar, that has been given the name PSR J1023+0038, shortened to J1023. It emits radiation from both its poles that occasionally reach Earth and also appears to have two different “settings” of brightness. Initially, the behaviour of J1023 confused experts, but now they believe that the stark difference in brightness levels has to do with the star launching out matter over short spaces of time. Maria Cristina Baglio, leader of the research team and scientist at New York University, Abu Dhabi, said in a statement: “We have witnessed extraordinary cosmic events where enormous amounts of matter, similar to cosmic cannonballs, are launched into space within a very brief time span of tens of seconds from a small, dense celestial object rotating at incredibly high speeds.” In addition to the pulsar emitting matter, over the last 10 years, scientists have witnessed the star pulling material from its companion star. The material it is stealing forms a structure called an accretion disk that forms around the star itself. Since it began feeding, the star has been alternating between between “low” and “high” power modes. During moments of high power, the star shines brightly with a variation of X-rays, ultraviolet and visible light. During low power, it emits radio waves and appears much dimmer. In June 2021, experts witnessed a star shooting out hot, luminous matter that has been compared to a cosmic cannonball as the star continually switched modes. J1023 has fascinated experts, who have been able to explain the way the star behaves by observing it. Despite solving many of its mysteries, the scientists aren’t done with it yet. With the Extremely Large Telescope (ELT) in northern Chile currently under construction, it is hoped that when it is ready, scientists will once more be able to observe the pulsar. Sergio Campana, research co-author and Research Director at the Italian National Institute for Astrophysics Brera Observatory, said: “The ELT will allow us to gain key insights into how the abundance, distribution, dynamics and energetics of the inflowing matter around the pulsar are affected by the mode switching behavior.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
