Astronomers discovered a star that was flooded with the Milky Way, at a speed of 2.5 million mph

Many stars sedate in the galaxies they inhabit, slowly circling around the galactic nucleus. However, it is not a star called the PSR J0002 + 6216. The PSR J0002 + 6216, discovered by astronomers, is rapidly moving along the Roman road and has absolutely incredible speeds.

Specifically, it travels from 1,130 kilometers per second (700 miles per second). It could have taken it from Earth to the Moon in 6 minutes. This is one of the fastest stars we've ever seen.

And boy, it's spectacular – reflects from the widespread cloud of the recent explosion of the supernova and leaves the trail by hitting it through the outer shell of the debris.

PSR J0002 + 6216 (in short, J0002, although preferred "Zoomy"), is a type of neutron star called the pulsar. A neutron star is the core of a star below a certain mass after the supernova has left.

Pulsars are highly magnetized neutron stars with extremely rapid braking rates that emit electromagnetic radiation when they rotate. If these jets are aligned correctly and rotate so that radiation on Earth flashes, we can see it – like a cosmic lighthouse.

"Thanks to a narrow tail, a similar arrow, and a random angle of view, we can follow this pulsar straight back to his birthplace," said astronomer Frank Schinzel of the National Radio Astronomical Observatory.

"Further study of this goal will help us better understand how these explosions can" kick "neutron stars at such high speeds."

Zoomy, which is approximately 6,500 light-years away (1,992 parsecs) in the constellation Cassiopeia, is approximately 53 light-years from the center of the bubble supernova, called CTB 1. The tail is observed in the radio spectrum, followed by 13 light years between the outer shell of the supernova particles and the star .

It acts like a kind of cosmic arrow that points directly to the birthplace of the pulsar.

"Measuring the pulse movement and tracking back indicates that he was born at the center of the remnant where the supernova explosion occurred," said Matthew Kerr of the Marine Research Laboratory, astrophysicist.

Researchers believe that the explosion of the supernova that created CTB 1 could be asymmetrical, somehow hitting the pulsar at high speed and sending it to space.

An explosion that the team could detect occurred about 10,000 years ago. Zoomy encountered the edge of the bubble supernova about 5000 years ago.

"The explosion particles in the supernova remain initially expanded faster than the pulse rate," said astronomer Dale Frail from the National Radio Astronomical Observatory. "However, the remains were slowed down due to his encounter with fragile material in the interstellar space, so that the pulsar could catch it and overtake it."

It moves so fast that it will eventually be able to escape from the Roman road and continue its speed through the intergalactic space.

Other neutron stars were also observed at these incredible speeds – the fastest was the RX J0822-4300, which traveled with an absolute jaw which fell to 1,500 kilometers per second.

Our friend Zoomy is still one of the fastest, although the average pulsar travels only about 240 kilometers per second. And it has the clearest signpost for the starting point. This is an incredible discovery, as it can help astronomers understand the dynamics that release these stars into space with such enormous speed.

One hypothesis is that instability in a fractured star could create an area of ​​a slowly moving substance that gravitatively pulls a neutron star against it, generates acceleration. It seems that Zoomy has been consistent with it so far – although of course more observations are needed.

"We still have a lot of work to fully understand what is happening with this pulsar, and it provides a great opportunity to improve our knowledge of supernova and pulsar explosions," Schinzel said.

Paper team was sent Astrophysics journals.
