A star that is a mere 240 yrs . old has been discovered by astronomers after it discrete a mighty burst of X-rays. It is the youngest of its kind ever found, checking ways of better understanding how such stars are formed.
First acquired by NASA’s Neil Gehrels Swift Observatory on March 12, follow-up studies by the European Space Agency have revealed more of the neutron star’s physical faculties, including those used to estimate its age.
Dubbed Swift J1818.0-1607, the star is a very young magnetar, a rare variety with extreme magnetic fields.
It was formed round the time of the American War of Independence, and is approximately 16,000 light years from Earth, located within the constellation Sagittarius.
It can be an important discovery, as astronomers have to date only found 31 magnetars. This could be the first witnessed at this early point in its cycle.
Magnetars are even more dense than typical stars, and also a tablespoon of the substance contained within you might have quite a few over 100 million tons. They are “dead” stars, having exhausted their nuclear fuel.
Because of those intense conditions, weird phenomena occur. Magnetars generate magnetic fields 1,000 times stronger than regular neutron stars.
In contrast, you can find over 3,000 known neutron stars. Discoveries such as for instance Swift J1818.0-1607 may help us understand just why there is this type of disparity between your number of neutron stars and magnetars.
“This object is showing us an earlier time in a magnetar’s life than we’ve ever seen before, very shortly after its formation,” said Nanda Rea, an astronomer at the Institute of Space Sciences in Barcelona and co-author on the research.
