A team of Chinese researchers discovered a stunning binary system In which the star object known as Pulsar’s orbit inside The outer layers of the star of her companion, which she cut off by removing her master’s inner inward and dispel them into space.
The conclusions that detailed in a A new study Published in the magazine Scienceis an incredibly rare example of a “cobweb star” Her companion, so named because of women’s arachnids, who swallow men after mating. And tediously that the gloomy scene is one of the best stars in the evolution phase called the common envelope phase that has never ever been Astronomers watched directly.
The Pulsars is quick to rotate the neutron stars – the incredibly dense stars core that remained after the supernova.
All about the eutricity of neutron stars – Most of their gravity. They are so firmly packed, they contain more mass than our sun -shaped, just a dozen miles that all their atoms and their components and electrons were crushed into neutrons, and only a teaspoon of this incredible matter weighs trillion pounds. Their powerful magnetic fields, billions of times stronger than Earth, are liberated by radio waves along their poles.
Next to beggars, some neutron stars become pulsaries that spin up to hundreds of times per second after the siphon of the star companion if it has. Their sweeping radiation fibers, like space beacons, look like a repetitive signal to observers.
The newly discovered Pulsar, the PSR J1928+1815, intrigued astronomers, as his radio impulses suggested that he was particularly close to his master, every 3.6 hours filling the orbit. They also noticed that sixths of the Pulsar orbit of the orbit would disappear, indicating that the host darkens it.
“It’s a big part of the orbit,” said Jin-Lin Han, co-owner of the National Astronomical Observatory. Gizmodo; “It’s weird, only a bigger companion can do it.”
Within four and a half years, the Han team watched the system closely using the five-hundred-meter aperture spherical radio telescope (FAST) in southern China, the most powerful disposable radio telescope in the world.
Their observations revealed that the star hostess was one to 1.6 times the mass of our sun, and the pulsar was more likely to be 1.4 stars. However, it took some extra sleep to determine the host’s star. Its strict orbit and the fact that it was found only in radio wavelengths, Giz markedRejected the fact that it is a sun -like star. And since it was big enough to darken the Pulsar, it had to be something bigger than the remains of the stars, such as another neutron star.
This pointed out something more impressive: a helium star, created after the Pulsar, when it was still commonly a neutron star, tore off her host layers and created a huge common envelope – a cloud of hydrogen gas that swallows both stars. In this case, the poor star in the offensive managed to stick to their evacuated internal inwardly only 1000 years – blinking in the life expectancy of the stars – against the whole, the powerful envelope collapsed. Proper as it was, its effect lasts: friction, which gas gradually gradually covered both stars closer.
Conventional envelopes are rare because the neutron stars that remove their companion, the process that causes it to rotate and end the pulse, usually leads to all the poor material. But if the companion is massive enough, most of it remains.
The discovery marks the first A spider star A Helle star was found. Although astronomers could not testify to the action envelope, these are some of the most convincing So far, evidence that this long -lasting stage of star evolution exists. In general, the team estimates that there are only 16-84 star systems throughout the bird trail – and despite all the chances, we had to see one.
